L DAMPER MOTOR 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. When the power cord is plugged into the wall receptacle and 117 volts A.C. is supplied to the
damper motor, the motor operates until the damper is opened and the damper switch closes.
Then the damper motor stops operation.
If the damper motor does not operate, check for A.C. voltage with a voltmeter at the motor.
1. Disconnect the power cord from the wall receptacle.
2. Disconnect the wire leads of motor and connect the meter leads to the wire leads of main
3. Re-connect the power cord into the wall receptacle. If 117 volts A.C. is indicated at the
5. Reconnect all leads removed from components during testing.
6. Reinstall the outer case (cabinet).
7. Reconnect the power supply cord after the outer case is installed.
8. 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 wire leads from the switch terminals and connect ohmmeter leads to the
common (COM.) and normally open (N.O.) terminals of the switch.
1. When switch actuator is pushed by the damper motor cam, the meter should be indicated a
closed circuit.
2. When power cord is plugged into the wall receptacle, the damper motor operates and
damper cam will start to rotate. When the switch actuator is released, the meter should be
indicated an open circuit. If improper operation is indicated, replace the damper switch.
5. Reconnect all leads removed from components during testing.
6. Reinstall the outer case (cabinet).
7. Reconnect the power supply cord after the outer case is installed.
8. Run the oven and check all functions.

CHECKING TEMPERATURE IN THE CONVECTION MODE
It is difficult to measure the exact temperature in the convection oven. An accurate thermocouple
type temperature tester must be used. A low priced bi-metal type thermometer is not reliable or
accurate. The temperature should be checked with outer case cabinet installed, approximately 5
minutes after preheat temperature is reached (audible signal sounds four times). The temperature
experienced may be approx. 30°F more or less than indicated on the display, however, in most
cases the food cooking results will be satisfactory.
Difference in power supply voltage will also affect the oven temperature. The Household power
supply voltage may sometimes become lower than the rated voltage (117 V) and cause
under-cooking. If the power supply voltage is 10% lower than the rated voltage, longer cooking time
is required by 10% to 20%.

wire leads, replace the motor and if 117 volts A.C. is not indicated, check the wire
harness and control unit.
