How to Fix / Troubleshooting
Safety: Unplug the microwave before accessing the door switch area.
Basic checks:
- 1. Check door operation: Open and close the door slowly. The interior light should turn on when the door is opened. If it does not, or if E11 appears, the door sensing circuit is suspect.
- 2. Inspect latch area: Look for broken plastic around the latch hooks or frame that might prevent the switch from actuating.
Advanced steps:
- 3. Access door switches: Remove the outer cabinet and control panel to reach the door switch assembly. Identify the door sensing switch (often separate from the primary interlock).
- 4. Test switch: Use a multimeter to check continuity as the door is opened and closed. Replace the switch if it does not change state reliably.
- 5. Check wiring and board input: Verify that the switch wires are secure and that the control board connector is firmly seated.
