Troubleshooting and Testing
Procedure
Letter
DAMPER MOTOR TEST
P
1. Disconnect power supply cord, and remove outer case.
2. Open the door and block it open.
3. Discharge high voltage capacitor. (See Warnings and Instructions on page 3-1)
4. Remove the back plate from the oven.
5. Disconnect the leads to the primary of the power transformer.
6. Ensure that the leads remain isolated from other components and oven chassis by using
insulation tape.
7. Disconnect the wire leads of motor and connect the meter leads to the wire leads of main wire
harness.
8. Reconnect the power cord into the wall receptacle.
9. If 240 volts A.C. is indicated at the wire leads, replace the motor and if 240 volts A.C. is not
indicated, check the wire harness and control unit.
10. Disconnect the power supply cord.
11. Open the door and block it open.
12. Discharge high voltage capacitor.
13. Reconnect all leads removed from components during testing.
14. Reinstall the outer case (cabinet ) and the back plate.
15. Reconnect the power supply cord after the outer case and the back plate are installed.
16. Run the oven and check all functions.

DAMPER SWITCH TEST
1. Disconnect the power supply cord, and then remove outer case.
2. Open the door and block it open.
3. Discharge high voltage capacitor. (See Warnings and Instructions on page 3-1)
4. Disconnect the leads to the primary of the power transformer.
5. Ensure that the leads remain isolated from other components and oven chassis by using
insulation tape.
6. Disconnect the wire leads from the switch terminals and connect ohmmeter leads to the
common (COM.) and normally open (N.O.) terminals of the switch.
A. When switch actuator is pushed by the damper motor cam, the meter should be indicated a
B. When power cord is plugged into the wall receptacle, the damper motor operates and
