[3] G: MONITOR SWITCH -1 AND/OR -2 TEST
1.Disconnect the power supply cord, and then remove outer case and rear cabinet.
2.Open the door full and block it open.
3.Wait for 60 seconds to discharge the high voltuge capacitor of the inverter unit.
4.Before performing this test, make sure that the interlock switches -1, -2 and the interlock relay RY1
are operating properly, according to the above Switch Test Procedure. Disconnect the wire lead from
the monitor switches -1, -2 (COM) terminals. Check the monitor switches -1, -2 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 screw driver through the upper 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 switches, reconnect the wire lead to the monitor switch (COM) terminals and
check the continuity of the 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 rear cover and the outer case are installed.
8. Run the oven and check all functions.
