Section 3 Troubleshooting and Testing

Component Test
MONITOR 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. Before performing this test, make sure that the secondary interlock switch and the primary
interlock relay are operating properly, according to the above Switch Test Procedure. Disconnect
the wire lead from the monitor switch (COM) terminal. Check the monitor switch operation by
using the ohmmeter as follows. When the door is open, the meter should indicate a closed
circuit. When the monitor switch actuator is pushed by a screwdriver through the lower latch
hole on the front plate of the oven cavity with the door opened (in this condition the plunger of
the monitor switch is pushed in), the meter should indicate an open circuit. If improper
operation is indicated, the switch may be defective. After testing the monitor switch, reconnect
wire lead to monitor switch (COM) terminal and check continuity of monitor circuit.
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.
HOOD THERMAL CUT-OUT 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. A continuity check across the thermal cut-out terminals should indicate an open circuit unless
the temperature of the thermal cut-out reaches approximately 158°F (70°C) or more. At that
temperature, the contacts will close. The thermal cut-out opens automatically at approximately
104°F (40°C).
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.
