Refer to the illustrations on the next page.
When the unit is plugged in and line voltage is
applied to the electronic oven control, the
following keyboard actions are used to set the
BAKE function:
• The clock is set to the time-of-day.
• The BAKE keypad is selected.
• The BAKE temperature is selected.
When the preceding events occur, the BAKE
relay energizes, and its contacts close. This
provides an electrical circuit through the BAKE
element and the thermal fuse to the neutral
side of the line*.
THE BAKE FUNCTION
2-2
As electrical current flows through the BAKE
element, it heats up. The temperature in the
oven is regulated by the temperature sensor.
If the temperature at the back of the oven
exceeds 360˚F, the thermal fuse will open,
and terminate the BAKE function.
The BROIL relay will also close to provide top
heat during the BAKE cycle. The BROIL relay
will cycle on approximately 20% of the bake
operation time.
To preheat the oven before a BAKE cycle, the
BAKE relay is closed for 100% of the preheat
time, and the BROIL relay closes for approxi-
mately 40% of the preheat time.
