Third Door Switch And Monitor
Switch Removal
Removal
1. Disconnect the oven power supply cord and remove
outer case.
2. Open the door and block it open.
3. Discharge high voltage capacitor.
4. Disconnect the wire leads from the switch.
5. Remove two (2) screws holding latch hook to oven
flange.
6. Remove latch hook assembly from oven flange.
7. Push outward on the two (2) retaining tabs holding
switch in place.
8. Switch is now free. At this time switch lever will be
free, do not lose it.
Reinstall
1. Re-install each switch in its place. The third door
interlock/ monitor switches are in the lower position
and the door sensing switch is in the upper position.
2. Re-connect wire leads to each switch. Refer to
wiring
diagram.
3. Secure latch hook (with two (2) mounting screws) to
oven
flange.
4. Make sure that the monitor switch is operating
properly and check continuity of the monitor circuit.
Refer to “Test Procedure and Adjustment Procedure”
To discharge the high voltage capacitor, wait for 60
seconds and then short-circuit the connection of
the high-voltage capacitor (that is the connecting
lead of the high-voltage rectifier) against the
chassis with the use of an insulated screwdriver.

Third Door Switch And Monitor Switch
Adjustment
1. Disconnect the power supply cord, and then remove
outer
case.
2. Open the door and block it open.
3. Discharge high voltage capacitor.
If the door sensing switch, primary switch, secondary
switch and monitor switch do not operate properly due
to a misadjustment, the following adjustment should be
made.
4. Loosen the two (2) screws holding latch hook to the
oven cavity front flange.
5. With door closed, adjust latch hook by moving it back
and forth, and up and down. In and out play of the
door allowed by the upper and lower position of
the latch hook should be less than 0.5mm. The
vertical position of the latch hook should be adjusted
so that the door sensing switch, primary switch and
third door switch are activated with the door closed.
The horizontal position of the latch hook should be
adjusted so that the plunger of the monitor switch is
pressed with the door closed.
6. Secure the screws with washers firmly.
7. Check the operation of all switches. If each switch
has not activated with the door closed, loosen screw
and adjust the latch hook position.
