[20] MONITORED INTERLOCK SWITCH, DOOR SENSING SWITCH AND MONITOR SWITCH
ADJUSTMENT
If the monitored interlock switch, door sensing switch and monitor
switch do not operate properly due to a mis-adjustment, the following
adjustment should be made.
1. Adjustment
1. CARRY OUT 3D CHECKS.
2. Loosen the two (2) screws holding the latch hook to the oven cavity
front flange.
3. With the door closed, adjust the latch hook by moving it back and
forward or up and down. In and out play of the door allowed by the
latch hook should be less than 0.5mm. The horizontal position of
the latch hook should be placed where the monitor switch has acti-
vated with the door closed. The vertical position of the latch hook
should be placed where the monitored interlock switch and door
sensing switch have activated with the door closed.
4. Secure the screws with washers firmly.
5. Make sure of the all switches operation. If the latch head has not
pushed the plungers of the monitor switch with door closed, adjust
the latch hook position. At that time, the latch head should have
pushed the plungers of the monitored interlock switch and door
sensing switch. If the latch head has not pushed the plungers of the
monitored interlock switch and door sensing switch with door
closed, loose two (2) screws holding latch hook to oven cavity front
flange and adjust the latch hook position.
2. After adjustment, make sure of following:
1. In and out play of door remains less than 0.5mm when latched
position. First check the latch hook position, pushing and pulling
upper portion of the door toward the oven face. Then check the
lower latch hook position, pushing and pulling lower portion of the
door toward the oven face. Both results (play of the door) should be
less than 0.5mm.
2. The contacts (COM-NO) of the door sensing switch and the moni-
tored interlock switch open before door is opened.
3. When the door is closed, the contacts (COM-NO) of the door sens-
ing switch close.
4. When the door is closed, the contacts (COM-NC) of the monitor
switch and monitored interlock switch open. And the contacts
(COM-NO) of their switches close.
5. Reinstall outer case and check for microwave leakage around the
door with an approved microwave survey meter. (Refer to Micro-
wave Measurement Procedure.).
