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
adjustment. Make sure that the latch moves
smoothly after adjustment are completed and that
the screws are tight. Make sure the primary,
monitor, and secondary switches operate properly
by following the continuity test procedure.
