ELECTRONIC CONTROLS - “E”
Sequence of Operation (With the Oven Doors Closed)
1. Line Voltage is supplied to the Mode Switch, Door Switch and the Momentary Light
Switch.
2. Set Mode Switch to COOK and close the oven doors. Line Voltage is sent from Mode
Switch to power up the Controller and to the AUX relay on the controller. With the
oven doors closed Line Voltage is sent to the 24 volt transformer.
3. Set desired temperature. The controller’s relays now close.
4. The AUX relay sends Line Voltage to the motor relay coil, closing the circuit to the
Hi/Lo Fan Switch. The motor now operational causes the centrifugal switch to close
and send the Neutral Voltage to the 24 Volt Transformer.
5. The bake relay completes the circuit from the 24 volt transformer to the ignition
module and *ignition occurs, heating the oven.
