1.
The interlock and monitor switches positions are not service adjustable.
If the screws on the hinges of the oven door are loosen, the door may not
be in a correct position. In this case, the interlock switches cannot be
operated by the latch pins of the door when the door is shut. To repair the
door, remount the door and fasten the screws on the door hinges.
2.
The monitor switch is provided to monitor the operation of the primary
interlock switch. If the primary switch fails to operate when the door is
open, the monitor switch will form a short circuit across the supply and the
fuse in the oven will blow. Electric arc may form across the switch
contacts of the primary interlock switch, the secondary switch and the
monitor switch. The switches may then be damaged. If the fuse is
blown due to the failure of the primary interlock, repair the failed
mechanical parts and replace all the interlock switches.
IMPORTANT
After replacement of any part of the interlock and monitor circuit:
1.
Check if the microswitches are turned ON and OFF by the latches as
specified in the table above.
2.
Apply sealant to the screws and nuts of the door hinges.
3.
Check microwave leakage.
4.
Check if the oven will turn off instantly when the door button is pushed to
the position where the door latches leave the interlock switches.
