How to fix it
- Open and close the door several times; listen for the click of the switch.
- Check that the oven light toggles with door movement — if not, the switch isn't actuating.
- Inspect hinges for sag; replace hinges if the door drops or rubs.
- Power off, pull the trim, and test the switch with a multimeter for continuity change when pressed.
- Replace the door switch if it fails the continuity test.
