Common Symptoms
- Microwave does not start when the door is closed
- Microwave shuts off or loses power during door operation
- Household fuse or microwave fuse opens repeatedly when the door is operated
- Intermittent operation associated with door movement
Check Before Replacing
- Disconnect power before inspecting or testing the switch.
- Inspect the switch body, actuator, terminals, wiring, and included fuse for visible damage, looseness, scorching, or broken connections.
- With all switch wires disconnected and power removed, check continuity across the monitor-switch terminals in the door-open and door-closed positions according to the applicable Whirlpool service documentation.
- Verify that the door-interlock mechanism actuates the switch correctly; do not adjust the switch or operate the microwave with panels or safety components removed.
- If a fuse is open, inspect the complete door-interlock circuit and related switches before replacing the fuse or switch.
Pro Tip
Do not diagnose this part from a no-heat complaint alone. Confirm the monitor-switch continuity and door-interlock actuation with power disconnected, because other interlock switches and circuit components can produce similar symptoms.
