Possible Causes
How to Fix / Troubleshooting
Safety: Unplug the microwave before inspection. Do not attempt to bypass door switches.
User-level steps:
- 1. Check interior light behavior: Open and close the door and observe the interior light. It should turn off when the door is closed (depending on model). If it stays on or behaves inconsistently, a switch may be stuck.
- 2. Clean door area: Wipe the door frame and latch area to remove sticky residue or food that might prevent proper switch actuation.
- 3. Operate door gently: Open and close the door several times, listening for distinct clicks from the switches. If clicks are weak or absent, a switch may be faulty.
- 4. Power reset: After cleaning and exercising the door, unplug for 5 minutes, then plug back in and test.
If E15 remains, the door switch assembly should be tested and replaced by a professional, as incorrect handling can defeat safety interlocks.
