Possible Causes
Misaligned door latch, failed door switch, bent door hinges, broken wiring to door switch
How to Fix / Troubleshooting
Safety first: Disconnect power before adjusting hinges or accessing internal switches.
- Check door closure: Close the door firmly and check that it is flush with the cabinet on both sides. If it sags, hinges may be bent.
- Latch inspection: Open the door and inspect the latch strike on the oven frame. Ensure it is not loose or deformed.
- Switch test: Locate the door switch (usually behind the front frame). With power off, remove the front trim and test the switch with a multimeter for continuity when pressed and released.
- Adjust or replace: Adjust the latch position if possible so that the switch is fully actuated when the door closes. Replace a faulty door switch or door latch assembly if it does not operate correctly.
- Hinge replacement: If the door does not align properly, replace the oven door hinges as a set.
Tip: Do not slam the door; repeated impact can damage the latch and switch.
