INTERLOCK SWITCH SYSTEM

Oven door
status
Open
Close
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.
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 rupture. An 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
A
fter replacement of any part of the interlock and monitor circuit:
Check if the microswitches are turned ON and OFF by the latches as specified in the table
above.
Apply sealant to the screws and nuts of the door hinges.
Check microwave leakage.
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.
