L. INTERLOCK SYSTEM
1)INTERLOCK MECHANISM
The door lock mechanism is a device which has been specially designed to eliminate completely microwave activity when the door is opened during cooking and thus to prevent the danger resulting from the microwave leakage.

2)MOUNTING OF THE PRIMARY/MONITOR/ SECONDARY SWITCHES TO THE LATCH BOARD
3)INSTALLATION AND ADJUSTMENT OF THE LATCH BOARD TO THE OVEN ASSEMBLY
•Mount the latch board to the oven assembly.
•Adjust the latch board in the arrow direction so that oven door will not have any play in it when the door is closed.
•Tighten the mounting screw.
•Check for play in the door by pushing the door release button. Door movement should be less than 0.5 mm. (1/64 inch)
Don't push the door release button while making this adjustment. Make sure that the latch moves smoothly after adjustment is completed and that the screws are tight. Make sure the primary, monitor, and secondary switches operate properly by following the continuity test procedure.
