Blue conductor is neutral.  
Green conductor is ground.  
CONTROL BOX AUTO  
COOL DOWN  
When the temperature in the control box reaches 120°F ± 3°F (48.9°C  
± 1.7°C), the cooling fan thermostat will switch power to the control  
box cooling fan. The thermostat will interrupt power to the cooling fan  
when the control box temperature falls to 100°F ± 3°F (37°C ± 1.7°C).  
Electrical power is permanently supplied through three 50 A fuses to  
the normally open contacts of the heat relay. Power is also supplied,  
through the 10 Amp motor and control fuse, through the normally  
closed control box hi-limit thermostat, to the normally open oven power  
switch. Power is also supplied to the control box cooling fan  
thermostat. Closing the oven power switch supplies line voltage to the  
main fan motor. Closing the oven power switch also supplies line  
voltage to the heat circuit and to the primary of the oven control  
transformer.  
MAIN FAN CIRCUIT  
HEAT CIRCUIT  
Closing the oven power switch supplies line voltage through the main  
fan air pressure switch, through the normally closed oven cavity hi-limit  
thermostat, to the oven control  
TEMPERATURE CONTROL Closing the oven power switch supplies line voltage to the primary of  
the control transformer and through the air pressure switch and oven  
cavity hi-limit, to the oven control. Secondary voltage, 24VAC, is  
supplied to the oven control. The oven control is set to desired  
temperature. The thermocouple will provide varying millivolts to the  
oven control. The oven control supplies line voltage to the heat  
contactor at intermittent intervals to maintain desired temperature. The  
display on the oven control will indicate when the heat contactor is  
energized.  
NOTE: The display also indicates oven temperature.  
CONVEYOR DRIVE  
Closing the oven power switch supplies line voltage to the conveyor  
motor and to the primary of the control transformer. Secondary  
voltage, 24VAC, is supplied to the oven control. Setting the oven  
control to the desired time outputs voltage, through a reversing switch,  
to the conveyor motor.  
NOTE: The conveyor system uses a hall effect sensor and magnet to  
prove operation of the conveyor motor. If the motor is not running,  
“BELT JAM” is indicated on the display.

voltage, but no secondary voltage, replace control  
transformer.  
Oven control  
Check for 24VAC supply to oven control. If no voltage is  
present, trace wiring back to control transformer. Check  
for supply voltage to oven control. If no voltage is  
present, trace wiring back to hi-limit thermostat. If  
voltage is present, check for a read-out on the display. If  
there is no read-out on the display, replace oven control.  
If there is a read-out on the display, set the oven control  
to maximum temperature (see installation operations  
manual for temperature adjustment). With the oven  
control at maximum temperature, check for supply  
voltage to the heat contactor. If there is voltage at the  
heat contactor, proceed to “Heat contactor “. If there is  
no voltage at the heat contactor, trace wiring back to the  
oven control. If there is no voltage output at the oven  
control, check the read-out on the oven control. If the  
oven control reads “PROBE FAIL” this indicates that the  
thermocouple has failed or become disconnected from  
the oven control  
Contactor, hi-limit (Model  
1421-000-E only)  
Check for supply voltage to contactor coil. If no voltage  
is present, trace wiring back to oven cavity hi-limit  
thermostat. If supply voltage is present at the coil, check  
to see that contacts are closed. If there is voltage to the  
coil and the contacts are not closed, replace contactor.  
Check to see that the thermocouple is securely  
connected to the oven control. If the thermocouple is  
connected to the oven control, and the display indicates  
“PROBE FAIL”, disconnect the thermocouple from the  
oven control and measure the resistance of the  
thermocouple. The thermocouple should read approx.  
11. If these readings are not achieved, replace the  
thermocouple. If these readings are correct, proceed.  
If the thermocouple checks good, but the oven control  
display indicates that there is a thermocouple failure,  
replace the oven control. If the oven control indicates a  
temperature reading, but the oven will not heat, proceed.

DC millivolt output of the thermocouple. Refer to the  
thermocouple chart (located in the “Removal” section of  
the manual) for proper millivolt readings. If these  
readings are not achieved, replace thermocouple.  
If the thermocouple checks good, but there is no supply  
voltage output to the temperature regulation valve,  
replace the oven control. If there is supply voltage output  
to the heat contactor, proceed.  
Check for supply voltage to the heat contactor. If voltage  
is present, listen for contacts to open and close. Also  
check for opens or shorts in the operating coil. Replace  
heat contactor as needed.

Intermittent heating  
Conveyor will not run  
Thermal/overload of main fan The main fan motor is equipped with internal thermal  
motor  
protection and will cease to operate if overheating  
occurs. As the motor overheats and cool, this will cause  
the heating system to cycle on and off intermittently.  
Improper ventilation or lack of preventive maintenance  
may cause this problem. Also most of the problems  
listed under “Oven will not heat” can cause intermittent  
failure.

Check for line voltage supplied to switch. If no voltage  
is present, trace wiring back to fuse holder. Check  
continuity between switch terminals. Replace switch as  
needed.  
Control transformer  
Conveyor motor  
Check for supply voltage to primary of control  
transformer. If no voltage is present, trace wiring back to  
oven power switch. If voltage is present, check for  
24VAC at transformer secondary. If there is primary  
voltage, but no secondary voltage, replace control  
transformer.  
Check for supply voltage to the conveyor motor at  
terminal #8 to neutral. If no voltage is present, trace  
wiring back to oven power switch. If voltage is present,  
but the motor will not run, check the motor windings for  
opens or shorts. If any of the above checks fail, replace  
conveyor motor.  
Capacitor, conveyor motor  
Check for shorts or grounds. Replace capacitor as  
needed.  
WARNING: Capacitor has a stored charge, discharge  
before testing.
