GENERAL INFORMATION  
RECEIVING  
soon as cool enough using dry cloth. If not cleaned,  
there may be noticeable smoke, odor, or visible dirt  
the next time the unit is used.  
Inspect unit thoroughly at time of delivery. Report any  
visible damage to the carrier immediately. If the damage  
is "concealed" and not discovered until after delivery has  
been accepted, make a "concealed damage report" to the  
carrier. "Concealed damage report" forms may be ob-  
tained from the carrier's agent.  
3. Crazing - Craze is the name given to the small hair  
line marks which are sometimes found in enameled  
surfaces after use. They look like little cracks, but  
they are not. The enamel around them will never chip  
or peel off due to these marks. As we cannot  
guarantee enamel against crazing or discoloration,  
thecustomershouldbeinformedastothepropercare  
of enamel.  
This procedure must be followed: All shipments, i.e.,  
complete range or parts, are shipped at the buyer's risk.  
Manufacturer's responsibility ends when the consignment  
is accepted by the carrier in "good order". Manufacturer  
will give every assistance on damage claims by supplying  
any necessary supporting papers, such as invoices or bills  
of lading. It must be understood that this assistance does  
not imply acceptance of responsibility for settlement of  
such claims. Claims for loss or damage cannot be de-  
ducted from the invoice or payment of the invoice cannot  
be withheld pending adjustment of claims. Do not return  
any unit or parts for credit without written consent.  
To the customer, any mark is a defect, as they do not  
understand enamel. They are afraid the enamel will  
peel or crack off leaving a rusty spot. This is not true  
as craze marks will never peel or crack. A craze mark  
is simply a place where the outer coat of enamel has  
separated. The dark color that appears in the crack  
is dust that catches in the opening.  
To service a craze complaint, it is best to use the  
following: Explain crazing to the customer using as  
an illustration the effect of hot water in a cold glass -  
it cracks. Compare it to the hairlines in dishes and  
cups due to continued heating and cooling. If the  
customer can be made to understand that the enamel  
will never come off, the customer will be satisfied.  
CARE AND HANDLING OF PORCELAIN ENAMEL  
1. Porcelain enamel is glass that has been fused onto a  
metal surface. Because it is glass, however, it cannot  
be guaranteed.  
It is impossible to make perfect color match in com-  
mercial enamel, and occasional variations must be  
expected. Minor imperfections are not just causes for  
complaint or rejection.  
One point to remember with service calls on crazing  
is to take care of it immediately. The longer the  
customer has to wait, the worse it appears to her.  
While this is true of all service work, it is especially  
true of crazing complaints. Make it a point to go out  
the same day the complaint is received.  
Porcelain will not stand heavy, sharp blows from  
cooking utensils or any other object.  
In cleaning enamel, soap and water will usually  
suffice. Remove any discoloration promptly, but do  
not apply cold water to a hot surface.  
CARE AND HANDLING OF CHROME, GLASS, OR  
METAL FINISH  
To keep the stainless, chrome, or glass finishes "looking  
new"washwithsoapandwater, rinse, thendrywithaclean  
cloth. If a polish is necessary, only the highest quality  
chrome cleaning compounds are recommended.  
Fruit juices, vegetable acids, sour milk, or strong  
mineral acids may discolor or etch enamel.  
2. Cleaning Broiler Pan  
Finger marks and smears may easily be removed with a  
mild cleaner such as glass wax and simonize cleaner.  
Suchagentsshouldbeusedsparingly. Neveruseordinary  
steel wool as it may leave a film of iron which will rust and  
discolor creating the illusion that the finish is rusting.  
For simplest method of cleaning, it is recommended  
that broiler pan be submerged in warm water imme-  
diately after use. Use a stiff brush, if necessary.  
Reheating broiler pan after it has been used without  
cleaning will result in fats and greases burning on and  
becoming much more difficult to remove.  
Never use harsh, gritty cleaners which can "age" or dam-  
age the porcelain and/or polished metal trim.  
NOTE: After the food has been removed from the  
ovenorbroiler, andtheunithasbeenturnedoff, leave  
theovenandbroilerdooropenforafewminutestodry  
outtheinterior. If foodhascookedoverorgreasehas  
spattered the interior, clean the parts thoroughly as  
Never use strong chemical oven cleaners in a self-clean  
oven. They are unnecessary and their residues can  
produce noxious odors during self-clean, with oven tem-  
peratures of 900°F. or more.

INSTALLATION INSTRUCTIONS  
INSTALLATION  
Location  
The location of the range should be selected so proper  
illumination, freedom from drafts, and convenience to  
other appliances in the kitchen are obtained. Carefully  
level the range, using the leveling legs provided. The  
range must be level in order to assure uniform cooking and  
baking. A level or a large pan of water placed on an oven  
rack or on top of range can be used to level the unit. The  
range is to be installed flush to rear wall, and may be  
installed flush to side base cabinets. Spacing to vertical  
side wall above cooking surface 3" (as shown in Figure 2),  
6" (as shown in Figure 3), for ranges with elevated ovens.  
Minimumdistancetohorizontalcombustiblesurfaceabove  
cooking surface is 30" and must be the width of the range.  
Maximum depth of cabinets installed above the range is  
13".  
Ranges With Elevated Ovens  
Figure 5  
It is the responsibility of the installer to comply with the  
installation clearances specified on the rating plate  
attached to the appliance.  
NOTE: Clearance specified to combustible construction  
(walls and materials) are based on a temperature rise of  
woodstructuresresultingfromapplianceoperation. These  
clearances are suitable for walls of studding, lath and  
plaster, or other types of combustible materials which have  
a density of 20 pounds per cubic foot or more. No  
evaluation of the clearances required has been made for  
installations adjacent to low density cellulose, fiber board,  
and similar materials which have a density of less than 20  
pounds per cubic foot; nor to plastic tiles, or sheeting.  
SECURE RANGE TO HOUSE STRUCTURE  
For safety consideration means have been provided for  
this range, except one having an elevated oven, to be  
secured to th house wall behind the range, METHOD 1#  
(see Figure 5A). If the wall behind the range is solid wood  
or a vertical stud is available, a wood screw or lag bolt of  
sufficient length may be employed to secure the range. If  
the wall behind the range is not solid such as paneling or  
dry wall (sheet rock) construction use of a Molly Bolt is  
required. The anchor portion of the Molly Bolt should be of  
sufficient lenght to hold it securely to the building material.  
The thicker the material, the longer the anchor portion  
must be.

INSTALLATION INSTRUCTIONS  
Where local codes permit, a TEMPORARY CONNEC-  
TION may be made to properly ground a two-prong wall  
receptacle by the use of an adaptor which is available at  
most local hardware stores.  
An adaptor plug can temporarily be used (see Figure 4)  
preferably with polarized male blades. If an unpolarized  
adaptor plug must be used, determine which is the "hot"  
side and ground. Place an identifying mark on the adaptor  
to assure proper polarization in the future.

Operating and Testing Procedures.  
UNIVERSAL GAS ORIFICES  
With the exception of the Broiler Burner and Sealed Top  
Burner, orifices for these models are of the coaxial type.  
They contain a double coaxial orifice hood and universal  
pin. The hood orifice is sized for Natural Gas (6 inches  
water column pressure). The pin orifice is sized for LP Gas  
(11 inches water column pressure).  
When making any temperature adjustments, a reliable test  
instrument should be used to accurately determine the  
oven temperature.  
A reliable test instrument of the thermocouple type is  
preferred which will allow temperature readings with the  
door closed.  
The orifice is adjusted for Natural gas as shipped from the  
factory. It must be adjusted for use on LP gas. This  
requires that the orifice hood be screwed or turned down  
approximately two (2) turns onto the pin. The hood should  
be turned down snug but not tight to the point where it  
damages or distorts the pin. (See Figure 19.)  
Position the thermocouple clip of the test instrument on the  
centeroftheovenrackthatispositionedinthecenterofthe  
oven cavity. The thermocouple of the test instrument  
shouldbe"weighted"or"loaded"inordertorepresentmore  
closely the average cooking temperature of the oven  
versus the on-off cycling of the thermostat with the full rate  
gas valve. The procedure for loading a thermocouple is  
illustrated in Figure 20.  
When set up for Natural Gas, gas flows around the pin and  
through the orifice of the hood which is sized for Natural  
Gas. When the hood is screwed down for LP gas, the gas

OVEN THERMOSTAT KNOB ADJUSTMENT  
Models without electronic Range Control (ERC)  
Figure 32 - "Loading" A Thermocouple  
An 8 1/2 x 11-inch piece of aluminum foil should be folded  
five (5) times, doubling the thickness with each fold. After  
the fifth fold, place the thermocouple in the center of the  
aluminum piece as shown and fold once more. Finally, fold  
the sides so the foil clings to the thermocouple. The loaded  
thermocouple will then provide temperature readings on  
the thermometer that more closely resemble the mean or  
average temperature of the oven as it cycles on and off  
above and below the temperature setting.  
Cooking recipes are written to take into consideration that  
oven thermostats have manufacturing tolerances, and  
may not provide an average temperature exactly on the  
thermostat setting. If the temperature average reading is  
beyond the ±25° tolerance range, a limited adjustment can  
be made with the adjustable skirt on the knob. The  
adjusting screw on the thermostat is sealed and no adjust-  
ment can or should be attempted. The rear of the adjust-  
able skirt shown here is self-explanatory.  
With all the controls properly set for "Bake", turn the oven  
thermostat to 350°.

temperature that the oven cycles ON and OFF. For  
example, at 350° setting the oven cycles between 335° and  
355°. This provides a mean or average temperature of  
345°F., well within the ±25°F specification.  
GAS PRESSURE  
Correct ignition and operation of the burners are dependent  
upon adequate gas pressure. The regulator is designed to  
provide pressure of approximately six (6) inches water  
column pressure (WCP) for natural gas and approximately  
eleven (11) inches for WCP for liquid propane (LP) gas,  
provided the universal type gas regulator and gas valves  
have been correctly set up for the type gas employed.  
Thesepressuresthereforerequirethattheminimumsupply  
pressure to the regulator must be at least six (6) inches  
WCP for natural gas and eleven (11) inches WCP for LP  
gas, with maximum pressure not to exceed fourteen (14)  
inches WCP.

MEASURING GAS PRESSURE  
Equipment for measurement of gas pressure varies from  
pressure meters and gauges to the relatively simply and

A manometer is simply a U-shaped tube of clear plastic or

support against the atmospheric pressure on top of the  
water column. The manometer therefore indicates gas  
pressure in inches water column. This conforms with the  
gas specifications for gas appliances which are given as  
inches WCP or inches water column pressure.  
USING THE MANOMETER  
The usual procedure for taking the pressure reading is to  
connect the tubing to one of the gas valve orifice hoods and  
turn on the valve. A full load reading should be taken by  
turning on all of the top burners and the oven burner to  
assure that the pressure under a full load is adequate.

are easily hit. UTENSIL HANDLES SHOULD BE  
TURNED INWARD AND NOT EXTEND OVER AD-  
JACENT SURFACE BURNERS to minimize burns,  
ignition of flammable materials, and spillage due to  
unintentional contact with the utensil.  
SAFETY PRECAUTIONS READ BEFORE OPERATING  
THE RANGE.  
12. Neverleaverangeburnersathighheatsettings. Boil-  
over causes smoking and greasy spillovers that may  
ignite.  
Accidents are always tragic, especially because so many  
of them could have been prevented with a little care and  
judgement. Here are some basic good practices to follow  
for safe use of the gas range.  
13. Clean range with caution. If a wet sponge or cloth is  
used to wipe spills on a hot cooking area, be careful  
to avoid steam burns. Some cleansers can produce  
noxious fumes if applied to hot surfaces.  
1. Be sure the range is installed by a qualified technician  
and is properly grounded.  
2. Never use the range for warming or heating the room.  
This warning is based on safety considerations.  
14. Do not touch surface area near burner units and  
burner caps. During and after use, these areas may  
be hot enough to cause burns. Avoid contact with  
these areas by clothing or other flammable materials  
until they have had sufficient time to cool.  
3. Wear proper apparel  
-
loose fitting or hanging  
garments should never be worn when operating the  
range.  
15. Do not heat unopened food containers - build-up of  
pressure may cause container to burst and result in  
injury.  
4. Do not repair or replace any part unless specifically  
recommended in the manual. All other servicing  
should be referred to a qualified service technician.  
5. Flammable materials should not be stored near the  
range.  
6. Do not use water on grease fires. Smother fire or 16. Do not store items of interest to children in

handled carefully. Never leave any cooking opera-  
tion unattended. Let fat cool before attempting to  
handle it. Wipe spillovers immediately.  
8. Children should not be left alone or unattended in  
area when the range is in use. They should never be  
allowed to sit or stand on any part of the range.  
18. Burner flame should be adjusted so that they do not  
extend beyond the edge of the utensil. This warning  
is based on safety considerations.  
9. Select utensils large enough to properly contain food  
and avoid boil-overs or spillovers. This will both save  
cleaning and prevent hazardous accumulations of 19. Never sit, step, or stand on any part of the range or

injury may result.  
10. TYPE OF UTENSILS - Avoid pans that are unstable  
and easily tipped. In choosing pans, look for easily  
grasped handles that will stay cool. Pans that are too  
heavy when filled with food can also be a hazard. If  
pan handles twist and cannot be tightened, discard  
the pan.  
11. HANDLES - Always turn pan handles to the side or  
back of the range - not out into the room where they

cycle the burner will cycle on and off. For programming

Control.  
SAFETY TIPS  
Some "common sense" rules to remember:  
Things to Remember:  
·
Always be certain that the oven parts are cool before  
touching them when hands are not protected by a  
potholder.  
CLOSE THE DOOR COMPLETELY FOR ALL BROILING.  
·
·
Always use a dry potholder, never a moist one, nor a  
trailing cloth, to avoid possible burns from steam.  
Pulling out oven racks is a convenience when lifting  
heavy foods, but caution should be used against  
possible burns from touching hot surface.  
For your safety, never use the range as a space  
heater.  
Do not heat unopened containers such as jars, cans,  
etc., in the oven. The build-up of pressure may cause  
thecontainertoburstandcancauseseriouspersonal  
harm or damage the range.  
Do not use aluminum foil on the racks or oven bottom.  
This will hinder heat circulation.  
Do not use aluminum foil on the racks or oven bottom  
when cleaning. The self-cleaning feature makes this  
unnecessary.  
Do not attempt to clean the oven or broiler burner  
ignitor assembly. The ignitors are electrically oper-  
ated and the danger of electric shock is present.  
Do not place baking utensils directly on the oven  
bottom.  
Do not use disposable or substitute broiler pans. The  
broiler pan and grid provided with the range have  
been scientifically designed to keep drippings cool so  
they will not become hot enough to ignite.  
Always remove the broiler pan and grid from the oven  
when baking and roasting. A possible fire hazard  
could exist if a soiled pan and grid are left in the oven.  
Also, any drippings on the grid will become baked on  
and will be very difficult to remove.  
Never cover the broiler grid with aluminum foil. It may  
trap grease and cause it to smoke. If desired, place  
a sheet of aluminum foil to line the broiler pan  
underneath the broiler grid to ease clean up. (A cup  
of water placed in the broiler pan will also minimize  
clean up.)  
Ultra-Ray® consumes most smoke and spatter. Kitchen  
stays cleaner, cooler.  
DO NOT PRE-HEAT THE BROILER BEFORE USING.  
·
·
BAKING  
For best results preheat the oven first. Turn the selector  
dial to "Manual" and the thermostat dial to the desired  
temperature. The oven will light automatically. Allow the  
oven to heat to temperature, approximately fifteen (15)  
minutes. For programming information on models with the  
Electronic Range Control, see Section III, Operation and  
Troubleshooting, ERC Control.  
·
·
The range is equipped with tilt proof oven racks with  
automatic stops. The oven racks are removable and can  
be inserted at various levels. They can be pulled to the  
"STOP" position without danger of tipping. To remove the  
racks, pull to the stop position, raise the forward edge, and  
lift. Reverse the procedure to install racks. One or both  
oven racks can be used during baking.  
·
·
·
Always keep in mind that heated air in the oven must be  
allowed to circulate freely. Leave at least 1 1/2" between  
utensils and between utensils and the oven walls. For  
example, never place one cake layer directly over another  
- stagger them within the oven.  
·
·
·
·
Never use the range as storage space.  
Never store flammable items in the storage drawer.

The Tri-Set valves are equipped with metered, fixed  
orifices, and the low setting cannot be adjusted. As there  
are air shutters, the burner flames can be adjusted in  
accordance with the Adjustment and Calibration Instruc-  
tions.  
The HI-LOW valves on other models are similar but  
without the "click" stops.  
TOP BURNERS  
The top burners consists of a burner and integral cap, a  
flash tube and support, a gas delivery tube including  
venturi and an adjustment air shutter. These burners are  
designed for trouble free operation with a minimum of  
parts.  
MODELS WITH SEALED BURNERS  
The top burners of these models are equipped with Tri-Set  
top burner valves. These valves provide flame adjustment  
for any size flame which is desired as well as "click"  
positions for "LO", "MED", and "HI" settings.  
Whenever a top burner gas valve knob is depressed and  
turned fully counterclockwise, the electrode built into the  
burner cap will start sparking and continue as long as the  
knob is held in this position. After the burner lights, move  
the knob to the "HI" position of the valve. At this time the  
sparking will cease. There are no standing pilots that have  
to be lighted or adjusted.

segments are lit. Following the lighting of all of the  
segments, the display will go through a "SALES

tions. The "SALES DEMONSTRATION" mode will  
show: (1) "BROIL", three (3) horizontal segments and  
the degree symbol, (2) "OVEN" "TIME" and ":00" , (3)  
"CLEAN", "TIME" and "3:00" (4) "TIMER" and ":00",  
(5) time of day, (6) all segments, and (7) "BAKE",  
three(3)horizontalsegmentsandthedegreesymbol.  
The program will continue to repeat until the "CAN-  
CEL" button is pressed. The time of day should then  
be displayed.  
The ERC has eight (8) function buttons to control minute  
timer, clock, stop time, bake, timed bake, broil, clean and  
set/cancel operations, and a rotary dial to set time and  
temperature.  
The ERC display consists of two (2) digital readouts which  
display the time of day, cooking time, cleaning time,  
minute timer time, stop time, baking temperature, lo/hi  
broil and failure codes as well as several indicators to show  
which function the ERC is controlling.  
The relay/power supply circuit board consists of two (2)  
relays for bake and broil operations which are controlled by RELAY/POWER SUPPLY CIRCUIT BOARD TESTING

tance change to a corresponding temperature readout.  
The ERC then cycles the bake/broil relays to maintain the  
desired temperature setting.  
Also remove the wire leads from the circuit board  
terminals E1 through E7. Using an ohmmeter, check  
for the following readings in Table 1 below. Refer to  
Figure 22 for correct terminal/pin location. Figure 23  
shows the relay/power supply circuit board sche-  
matic.  
The ERC is also capable of sensing certain failure condi-  
tions which can occur in the temperature sensor, the self-  
clean latch switch or the ERC itself. If the ERC senses a  
failure, power will be removed from the bake/broil relays,  
an alarm will sound, and a failure code will be displayed.  
Each major component of the Electric Range Control  
System (ERC, temperature sensor, or relay/power supply  
circuit board) is serviced as a separate part. However,  
each component and related wire harness must be tested  
prior to replacing an individual component.

approximately 108-132 VAC should be indicated. If  
a low voltage or no reading is indicated, check for  
loose connections or broken wiring.  
6. To check the bake relay contacts, shut off power to  
the range and attach your AC voltmeter leads to the  
relay board terminals E6 and E7 and turn on power to  
the range. A voltage reading of approximately 120  
VAC should be indicated. Program the ERC for a  
bake operation.  
2. To check the transformer secondary winding output  
(filament) voltage, shut off power to the range and  
insert your AC voltmeter leads into the J1 connector  
at pins J1-7 and J1-8 and turn on power to the  
appliance. A voltage reading of approximately 3.2  
VAC should be indicated. If no voltage is indicated,  
recheck primary input voltage (Step 1). If primary  
input voltage checks good, replace the relay/power  
supply board.  
When the ERC initiates the bake function, the voltage  
reading should drop to zero (0) VAC. If the voltage  
does not drop to zero (0) VAC, the relay is not being  
energized or the relay is defective.  
7. To check the broil relay contacts, shut off power to the  
range and attach your AC voltmeter leads to the relay  
board terminals E4 and E5 and turn on power to the  
range. A voltage reading of approximately 120 VAC  
should be indicated. Program the ERC for a broil  
operation. When the ERC initiates the broil function,  
thevoltagereadingshoulddroptozero(0)VAC. Ifthe  
voltage does not drop to zero (0) VAC, the relay is not  
being energized or the relay is defective.  
3. To check the transformer secondary winding output  
voltage (used to drive relays), shut off power to the  
range and insert your AC voltmeter leads into the J1  
connector at pins J1-6 and J1-5 and turn on power to  
the appliance. A voltage reading of approximately  
20.3 VAC should be indicated. If no voltage is  
indicated, recheck primary input voltage (Step 1). If  
primary input voltage checks good, replace the relay/  
power supply board.  
ERC OVEN TEMPERATURE SENSOR  
4. To check the bake relay drive voltage supplied to the  
relay/power supply board from the ERC, shut off  
powertotherangeandinsertyourACvoltmeterleads  
into the J1 connector at pins J1-2 and J1-1 and turn  
on power to the range. With no bake operation  
programmed into the ERC, zero (0) VDC should be  
indicated. Program the ERC for a bake operation.  
When the ERC initiates the bake program, a voltage  
reading of approximately 24 VDC should be indi-  
cated. If no voltage is indicated, check for loose  
connections or broken wiring, and also for drive  
voltage at the ERC J1 connector at pins J1-9 and J1-  
5.  
The oven temperature sensor is mounted in the oven  
cavity and electrically connected to the J2 connector, pins  
1 and 3 on the rear of the ERC. The sensor resistance  
changes with temperature changes inside the oven cavity  
and the ERC controls the oven temperature by reacting to  
the sensor resistance changes.  
The sensor resistance can be checked by removing the  
sensorinterconnectharnessplugfromtheERCJ2connec-  
tor and inserting the ohmmeter leads into the harness  
connector plug. A resistance reading of 1091 ± 5.5 ohms  
should be indicated at ambient room temperature (75°F.)

BAKE AND BROIL IGNITORS  
TO AVOID THE RISK OF ELECTRICAL SHOCK,  
PERSONALINJURYORDEATH DISCONNECTPOWER  
BEFORE SERVICING, UNLESS TESTING REQUIRES  
IT.  
The bake and broil ignitors are mounted to the bake and  
broil burners and ignite the gas flowing into the burner.  
During a broil or manual bake operation, current flows  
through the ignitor, gas valve, selector switch, and thermo-  
stat to neutral. As the ignitor starts heating up and glowing,  
its internal resistance decreases allowing more current to  
flow through the bake or broil circuit. When the circuit  
current reaches approximately 3.2 - 3.6 amps, the bi-metal  
arm in the gas valve flexes, opening the valve, allowing  
gas to flow to the burner where it is ignited by the glowing  
ignitor. The ignitors will glow anytime the bake or broil  
burners are in operation and cycle on and off with the  
thermostat cycling contacts.  
Figure 63 - Cook And Off Timer - Rear View - Partial  
The operation of the OVEN/BROILER "ELECTRIC IGNI-  
TOR" can be checked by using a VOLT/OHMMETER as  
follows: NOTE: This check must be made while the ignitor  
is at ambient room temperature.  
1. Disconnect electricity.  
2. Set the volt/ohmmeter on the RX1K ohms scale.  
(Zero the meter.)  
3. Remove ignitor from burner.  
4. Remove ignitor lead wire nuts and disconnect ignitor  
leads from range wiring.  
5. Connect ohmmeter leads to ignitor wire leads.  
6. If the meter indicates continuity (a low resistance  
reading), the ignitor is operative. NOTE: The cold  
resistance measurement can vary several hundred  
ohms. However, this test is for continuity without a  
dead short (zero ohms).

valve is operative.  
6. Reattach the two (2) wire terminals removed from  
Point A or Point B on the gas valve.  
Figure 65  
The ignitor may still be defective even though conti-  
nuity is indicated and it glows when the oven is set for  
bake, broil, or clean function. A more exact test can  
be made to measure the ignitor current with the oven  
operating. An ammeter should be inserted in series  
with one (1) lead of the ignitor or an amprobe can be  
attached to the lead to check the amount of current  
flowing through the ignitor circuit. With the oven  
turned on and the ignitor glowing red, a current  
reading of approximately 3.2 - 3.6 amps should be  
indicated. The ignitor can also be removed and  
bench tested, using the current test method and an  
AC jumper or test cord connected to the ignitor leads.  
Figure 66  
SELECTOR SWITCH  
The selector switch is a two (2) position switch used for  
"MANUAL" or "AUTOMATIC" bake operation. The selec-  
tor switch contacts can be checked for continuity by using  
a continuity tester or an ohmmeter set to the low ohms  
range and following the selector switch contact chart.  
Power to the oven must be turned off and the selector  
switch wiring removed when checking the contacts for  
continuity. Access to the selector switch contacts can be  
made by removing the control panel. NOTE: The selector  
switch is not found on models with the ERC.  
ELECTRIC GAS VALVE  
The bake and broil dual gas valve supplies the gas flow to  
the bake or broil burners. The valve contains bi-metalic  
arms attached to the valve seats and are wound with a  
small electric heater coil. When a current range of  
approximately 3.2 - 3.6 amps flows through the bake or  
broil circuit, the bi-metalic arm is heated causing it to flex  
orbend, allowinggastoflowtotheburnerwhereitisignited

Baking or roasting in automatic time cook mode provides  
the option of cooking for a specific time period starting  
immediately or delaying the start to a later time. For timed  
cook, starting immediately, push in the bake button and  
enter the cooking time period. The relay switches will  
close, the indicator arrow will be lit to indicate that the oven  
is on (thermostat must be set to a temperature setting and

is programmed either for timed cook or for the self-clean  
the indicator arrows will flash slowly to indicate a program  
is in operation. When a program is in operation, the time  
of day cannot be changed, only the program time can be  
advanced or reduced. If it is desired to stop a program  
before completion, turn the thermostat and selector to  
OFF. This will stop oven operation but not the clock timer

OPERATIONAL TEST  
5. Push self-clean button in. The following should take  
place immediately - three (3) hours (3:00) should  
appear in the display, the letter "C" should appear on  
the left side of the display, the oven-on symbol should  
also appear on the left and both switches should be  
closed. Manually, with "Time Set" control, turn the  
digital display down to one (1) minute. Allow the timer  
to countdown to 0:00 - display should return to time-  
of-day and the switches open.  
This test procedure requires power applied (120 VAC)  
either in the range or with 120 VAC line cord connected to  
terminals 1 and 2 for bench test. An ohmmeter or continu-  
ity tester should be alternately connected across switch  
terminals 11 to 12 and 13 to 14. Selector switch must be  
in "OFF" position and latch in open position (non self-  
clean). NOTE: With selector switch in "OFF" position and  
latch in open position, the timer switch terminals are  
disconnected from circuit power sources which could  
damage the ohmmeter.  
NOTE: A slight "click" can be heard whenever the  
relay switches open or close.

with one (1) lead of the ignitor or an amprobe can be  
BAKE AND BROIL IGNITORS  
attached to the lead to check the amount of current  
flowing through the ignitor circuit. With the oven  
turned on and the ignitor glowing red, a current  
reading of approximately 3.2 - 3.6 amps should be  
indicated. The ignitor can also be removed and  
bench tested, using the current test method and an  
AC jumper or test cord connected to the ignitor leads.  
The bake and broil ignitors are mounted to the bake and  
broil burners and ignite the gas flowing into the burner.  
During a broil or manual bake operation, current flows  
through the ignitor, gas valve, selector switch, and thermo-  
stat to neutral. As the ignitor starts heating up and glowing,  
its internal resistance decreases allowing more current to  
flow through the bake or broil circuit. When the circuit  
current reaches approximately 3.2 - 3.6 amps, the bi-metal  
arm in the gas valve flexes, opening the valve, allowing  
gas to flow to the burner where it is ignited by the glowing  
ignitor. The ignitors will glow anytime the bake or broil  
burners are in operation and cycle on and off with the  
thermostat cycling contacts.  
ELECTRIC GAS VALVE  
The bake and broil dual gas valve supplies the gas flow to  
the bake or broil burners. The valve contains be-metallic  
arms attached to the valve seats and are wound with a  
small electric heater coil. When a current range of  
approximately 3.2 - 3.6 amps flow through the bake or broil  
circuit, the bi-metallic arm is heated causing it to flex or  
bend, allowing gas to flow to the burner where it is ignited  
by the burner ignitor. The gas valve is located behind the  
storage drawer.  
The operation of the OVEN/BROILER "ELECTRIC IGNI-  
TOR" can be checked by using a VOLT/OHMMETER as  
follows: NOTE: This check must be made while the ignitor  
is at ambient room temperature.

The ignitor may still be defective even though conti-  
nuity is indicated and it glows when the oven is set for

be made to measure the ignitor current with the oven  
operating. An ammeter should be inserted in series

ROCKER SWITCH TESTING  
DOOR LATCH MECHANISM  
The rocker type switch on these models is a single pole,  
double throw switch used to control the oven light. The  
rocker switch contacts can be checked for continuity by  
using an ohmmeter set to the RX1 scale or a continuity  
tester. Set the switch to the position as shown in Figure 31  
and connect the meter or tester leads to terminals 2 - 3 and  
then to terminals 1 - 2. Continuity should be indicated  
across terminals 2 - 3 and open contacts should be  
indicated across terminals 1 - 2.  
Set the rocker switch to the position as shown in Figure 32.  
Continuity should be indicated across terminals 1 - 2 and

fails either test, it should be replaced.  
The door latch mechanism is used to insure the oven door  
is sealed tightly against the chassis during the clean cycle.  
The latch cannot be moved to the "CLEAN" position unless  
the door is closed. A thermal safety "jams" the lock  
mechanism during the clean cycle to prevent accidental  
opening of the door latch during cleaning. When the latch  
is jammed the latch cannot be moved to the "COOK"  
position.  
After the cleaning is completed and the oven cools, the  
latch is released and can be moved again to the "COOK"  
position.

The HI-LOW valves on other models are similar but  
without the "click" stops.  
TOP BURNER  
The top burners consist of a burner and intergral cap, a  
flash tube and support, a gas delivery tube including  
venturi and an adjustment air shutter. These burners are  
designed for trouble free operation with a minimum of  
parts.  
INDICATOR LIGHT TESTING  
If the oven (bake, broil, clean) operates normally but the  
indicator lights do not glow, check for voltage at the  
indicator light terminals. If voltage is present at the  
Figure 76  
indicatorterminalsandtheindicatordoesnotglow, replace  
the indicator light. If no voltage is present at the indicator  
terminals, check for loose connectors, broken wiring, or  
other defective components (thermostat, ignitor, etc.).  
NOTE: The oven indicator light and the clean indicator  
light operates on 120 VAC. Use caution when checking for  
indicator light voltages.  
OVEN LIGHT SWITCH  
The oven light switch can be tested using the same  
procedure as the fluorescent light switch.  
The fluorescent light components, oven light switch and  
indicator lights are located behind the backguard glass  
mounted to the backguard control panel.
