Procedure

MONITOR SWITCH TEST
H
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 primary interlock
relay are operating properly, according to the Switch Test Procedure. Disconnect the wire lead
from monitor switch (COM) terminal. Check 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 the wire
lead to the monitor switch (COM)
terminal 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 outer case is installed.
8. Run the oven and check all functions.
I BLOWN MONITOR FUSE 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. If the monitor fuse is blown when the door is opened, check the secondary interlock switch,
primary interlock relay (RY2), relay (RY1) and monitor switch according to the "Test
Procedure" for those switches before replacing the blown monitor fuse.
Before replacing a blown monitor fuse, test the secondary interlock switch, primary
interlock relay, door sensing switch and monitor switch for proper operation.
If the monitor fuse is blown by improper switch operation, the monitor fuse and monitor switch
must be replaced with "monitor fuse and monitor switch assembly" even if the monitor switch
operates normally. The monitor fuse and monitor switch assembly is comprised of a 20
ampere fuse and 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.
