- Microwave operation may stop or fail to respond consistently when the door is moved.
Check Before Replacing
- With power disconnected, inspect the switch body, actuator, terminals, and mounting area for visible damage or looseness.
- Verify the switch identification and position against the model-specific service documentation before replacement.
- Electrical continuity testing should follow the applicable service manual because microwave interlock circuits and switch positions are model-specific.
Pro Tip
