Possible Causes
Stuck or misaligned door switch, Shorted door sensor wiring, Control board not detecting door closed state
How to Fix / Troubleshooting
Safety: Disconnect power before adjusting door components.
- Check door closure: Ensure the door closes firmly and evenly. Listen for the click of the door switch.
- Inspect switch: Locate the door switch (often near the top or side of the cavity) and check for physical damage or sticking.
- Switch test: With a multimeter, test the switch for proper open/closed operation as the door is moved.
- Adjust or replace: Adjust the switch position if misaligned, or replace if it fails continuity tests.
Note: If the switch is working but the light and fan remain on, the control board may have a stuck relay or logic fault.
