Understanding the sequence of operation is necessary in properly trouble-shooting this appliance. In this section the sequence of operation will be covered first, as well as calibration and operation of components, and basic trouble shooting techniques for that specific model. Follow each sequence carefully, and get to understand its operation before moving on to trouble shooting.

MANUAL CONTROLS - "M"

Sequence of Operation (Starting with the oven doors in closed position.)

1.Turn the Mode Switch to the “Cook” position. This sends line voltage to the timer. And with the doors closed, line voltage is sent via the door switch to the thermostat and the Hi/Lo Fan switch.

2.Select Hi or Lo speed, the motor will now be operational.

3.Rotate the temperature dial to desired temperature. The thermostat will now call for heat sending line voltage to the 24 volt transformer. With the motor operating, the centrifugal switch is closed, completing the neutral circuit to the transformer.

4.The 24v transformer now sends 24 volts to the ignition module.
