How to Fix / Troubleshooting

Safety first: Unplug the microwave.

User-level checks:

Open and close the door slowly while watching the display; if the interior light or display flickers, the door switches may be intermittent.
Ensure the door closes squarely and is not obstructed.

Technician-level checks:

Test all door switches with a multimeter for reliable operation through multiple open/close cycles.
Inspect switch wiring and terminals for looseness or heat damage.
Adjust or replace the switch bracket if the switches are not being fully actuated.
If switches and wiring are good, suspect the control PCB.

Note: Door sensing is a critical safety function; any repair must be verified with proper leakage and safety tests.
