The control panel light switch assembly and when the thermostat is set to a cooking temperature, one set of contacts is all to the controls of the oven.

The second switch contact of this

With the power switch On (illuminated) power is directly supplied to the 60 minute bake timer, steam (water injection) switch, door microswitch, light switch, and the temperature control circuit. Accordingly the oven switched on from the oven thermostat.

Accordingly only the top outer element and the bottom element are used when a cooking circulation fan will operate when the door is closed, and with door open the oven light will switch assembly remains open in this setting and isolates power from the top element inner coil. The top element outer coil is directly temperature is selected. The control panel indicator light above the thermostat knob cycles On and Off with the thermostat to indicate when the elements are on and the oven is heating. will turn the oven light on when the door is

When the thermostat control is set to the Grill

The 60 minute timer is a mechanical timer and can therefore be operated with the oven’s capillary type thermostat which can be set to a position the first switch contact opens and the second switch contact closes. This arrangement allows power to be provided to power switch On or Off. However, only with the top element inner coil when the thermostat the oven’s power switch On will the switch is On, and isolates power from going to the contacts of the 60 minute timer turn on the bottom heating element. The top element time-up buzzer and illuminate the time-up outer coil which is directly fed from the oven indicator on the control panel. The buzzer thermostat switch is therefore On in and time-up indicator provide indication that conjunction with the top element inner coil the time setting has run down to zero and at when the thermostat is set to the Grill position. this point will remain On continuously until the

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 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. thermostat is factory set to 75°C (167°F) and will directly supply power to the bottom heating element as required to maintain its preset temperature.

If the main thermostat is turned On, power will also be supplied to the top outer element coil through the first switch contact of the thermostat front switch assembly. In this case 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.

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 turns off the contactor which removes power from the 3 hour timer and closes the contactor pole on the contactor that feeds the main oven thermostat.

The factory preset hold thermostat can be adjusted as required to change the holding temperature if necessary. Refer Service section for this procedure.

With a cold oven (ie room temperature) check that the top outer and bottom oven elements only are heating. Test the voltage across the bottom element and top element terminals at the rear of oven. If the voltage is correct then refer Fault: Bottom element not working

(trouble shooting section).

NOTE: If the main thermostat is set to off

(vertical) position and ‘Roast ‘n Hold’ mode is selected, then only the bottom element will heat.

If there is no voltage at the element terminals, check the voltage at terminal 2 (top) of the hold thermostat at bottom rear of control panel

(fig 6.3.12). If there is no voltage then check wiring.

If the voltage is correct, and the thermostat is adjusted above oven temperature, then check for output voltage at terminal 1 (bottom). If there is no voltage and the thermostat will not switch on then the thermostat is faulty— replace.
