The temperature control of this oven is with a  
capillary type thermostat which can be set to a  
required cooking temperature.  
3.2 EXPLANATION OF CONTROL  
SYSTEM  
The thermostat switch has a separate switch  
body assembled onto the front from the shaft  
assembly and when the thermostat is set to a  
cooking temperature, the switch contacts turn  
on the oven fan. The switch is closed (fan on)  
whenever the thermostat is not in the Off  
(vertical) position. The control panel indicator  
light to the right of the thermostat knob cycles  
On and Off with the thermostat to indicate  
when the elements are on and the oven is  
heating.  
The E1100 Turbofan convection oven  
features multi-function operator controls for  
which  
a
correct understanding of their  
operation is required before carrying out any  
service or fault repair work. The control  
device functions are explained as follows:  
A power switch on the control panel isolates  
all to the controls of the oven. With the power  
switch Off all functions of the oven are  
inoperable.  
The E1100 Turbofan convection oven has 9.9  
kW of electric heating elements, comprising of  
three 3.3kW elements at the rear of the oven.  
The elements are switched on and off by the  
main oven thermostat or hold thermostat via a  
four-pole 25 Amp contactor located inside the  
control housing. Only three poles of the  
contactor are used, one for each element coil.  
With the power switch On (indicator  
illuminated) power is directly supplied to the  
60 minute bake timer, steam (water injection)  
switch, light switch, and the temperature  
control circuit. The oven circulation fan will  
operate only when the thermostat is turned on  
and the oven door is closed. The control  
panel light switch will turn the oven lights on  
when the door is closed only when the light  
The E1100 Turbofan convection oven  
features a Roast-and-Hold system which can  
be used to automatically set the oven to a  
fixed holding temperature at the end of a  
timed cooking period. When the Roast-and-  
Hold switch is turned On the switch will  
illuminate and switch the power from the  
thermostat to the 3 hour roast timer.  
switch is held in.  
With the thermostat  
switched on, the oven lights will come on  
automatically when the door is opened, as this  
is controlled by the door microswitch.  
The 60 minute timer is a mechanical timer and  
can therefore be operated with the oven’s  
power switch On or Off. However, only with  
the oven’s power switch On will the switch  
contacts of the 60 minute timer turn on the  
time-up buzzer and illuminate the time-up  
indicator on the control panel. The buzzer  
and time-up indicator provide indication that  
the time setting has run down to zero and at  
this point will remain On continuously until the  
60 minute timer has been manually set back  
to the Off (vertical) position. The 60 minute  
timer does not control any other part of the  
oven’s operating system as this timer is  
independent of the temperature control and  
heating system.  
If the roast timer is in the Hold (vertical)  
position the timer switch contacts will be in  
their normally closed position and supply  
power directly to the Hold thermostat located  
behind the control panel.  
The Hold  
thermostat is factory set to 75°C and will  
supply power to the heating contactor as  
required to maintain its preset temperature.  
The thermostat heating light will also cycle  
On/Off as the Hold thermostat maintains  
temperature.  
In the Roast-and Hold mode the 3 hour timer  
can be set to a selected roasting time. During  
this time period the normally open switch  
contacts of the timer are closed. The timer  
has two change over switches and in this  
position one is used to supply power to its  
timing motor and the other is used to switch  
power directly to the main oven thermostat.  
During the 3 hour timer run-down period the  
oven temperature will be controlled by the  
main oven thermostat to the set temperature  
and operate as previously described.  
The steam (water injection) switch on the  
control panel can be operated whenever the  
power switch is On. The switch is momentary  
like the light switch and when depressed, will  
operate the electric solenoid valve at the rear  
of the oven and inject water across the oven  
fan from the flat spray (vertical) nozzle  
positioned at the rear of the oven. Releasing  
the steam button will close the solenoid valve.  
This feature is used to instantaneously add  
steam into the oven.  
Revision 4/F3591

-11-  
When the 3 hour timer has run down and  
reached the Hold position the two switch  
contacts change over to their normally closed  
position which isolates power from the timer  
motor and the oven thermostat. It also  
switches power back to the oven hold  
thermostat. At this point the temperature  
control is now maintained by the hold  
thermostat as previously described.  
To  
cancel the hold circuit the Roast-and-Hold  
switch is turned Off. This removes power  
from the 3 hour timer and restores the feed to  
the main oven thermostat. The Hold indicator  
light below the 3 Hour timer will illuminate  
whenever the oven is operating in hold mode  
(Roast ‘n Hold selected, and 3 Hour timer at  
zero position).  
The factory preset hold thermostat can be  
adjusted as required to change the holding  
temperature if necessary. Refer Service  
section for this procedure.  
The Troubleshooting Guide (Section 5) should  
be used to identify any incorrect oven  
operation. On correct identification of the  
operating fault the Troubleshooting Guide will  
make reference to the corrective action  
required, or refer to the Fault Diagnosis  
section and/or Service section to assist in  
correction of the fault.

Fan motor faulty  
6.1 FAULT DIAGNOSIS  
Check the supply voltage across motor termi-  
nals. If there is no voltage then check the  
electrical connections of wiring.  
6.1.1 OVEN DOES NOT OPERATE / START  
Incorrect electrical supply  
If voltage is correct then check the oven fan  
for free rotation. Remove any obstruction.  
Check that the voltage across phase and  
neutral (L1 and L2) terminals of terminal block  
is the voltage as stated on the unit’s electrical  
rating plate.  
If fan is free to spin and the voltage at motor  
terminals is correct, then the motor is faulty—  
replace.  
If incorrect, check electrical connection of  
supply wiring and / or check electrical supply.  
6.1.3 NO HEAT / ELEMENTS NOT  
WORKING (FAN OPERATES BUT NO  
HEATING INDICATOR)  
Power switch faulty  
With switch on, check voltage at terminal 1 of  
switch. If there is no voltage, check for fault in  
wiring. Check voltage at terminal 2. If there is  
no voltage then the switch is faulty - replace.  
No power to thermostat  
With the thermostat ON and the roast switch  
OFF, check for power at terminal 1 of the  
thermostat. If no power then check that  
power is being supplied to the roast switch  
(terminal 2).

on) then the thermostat if faulty - replace.  
thermostat switched on and door closed,  
check voltage to terminal com of microswitch.  
If no voltage check wiring to thermostat.  
If voltage correct then check voltage at  
terminal n.c. If no voltage then manually  
activate microswitch by bending the activator  
arm. If microswitch cannot be activated then  
it is faulty - replace. If the microswitch can be  
manually activated then it should be adjusted.

ON)  
n.c.  
Faulty contactor  
Microswitch  
With the thermostat on check that the coil of  
the heating contactor is energised (voltage  
between terminals A1 and A2). Check for  
output voltage from the contactor (terminals 1,  
3 and 5). If no output voltage (and input to  
terminals 2, 4 and 6 is correct) then the  
contactor is faulty - replace.

approximately three minutes below zero.  
Buzzer and time up indicator will continue until  
the timer is manually switched off (to vertical  
position).  
Fault with water valve  
Check voltage supply across the water valve  
solenoid coil with the steam switch depressed.  
If there is no power supply then check the  
control panel steam switch.  
6.1.9 NO TEMPERATURE CONTROL  
(TEMPERATURE OVERRUN)  
If power supply to the coil is correct,  
disconnect wiring to coil and check the  
resistance of the coil windings.  
Thermostat faulty  
Set thermostat to 50°C. Check voltage at  
terminal 2 on the thermostat. As the oven  
heats up, the thermostat contacts should  
open, cutting power to terminal 2 of the  
thermostat. If not then the thermostat is faulty  
- replace.  
Correct coil resistance: 2500 ohms  
NOTE: If open circuit / high resistance, then  
the coil is faulty—replace.  
If coil resistance is correct, rewire and listen  
for an audible solenoid click when the steam  
switch is depressed.  
If solenoid can be heard functioning, and oven  
water nozzle is not blocked, then remove  
water solenoid and fittings and check for  
blockages.
