Possible Causes

How to Fix / Troubleshooting
Safety: Unplug the microwave before inspecting door switch wiring or the control board.
Steps:
- 1. Gentle operation: Avoid slamming the door. Close it gently and see if E10 clears after a power reset (unplug for 5 minutes).
- 2. Inspect door area: Check for visible damage around the door frame, hinges, and latch area.
- 3. Internal wiring check (advanced): Remove the outer cover and inspect the wiring harness from the door switches to the control PCB. Ensure all connectors are fully seated and wires are not pinched or broken.
- 4. PCB inspection: Examine the control PCB where the door switch harness connects. Look for cracked solder joints or burnt traces.
Resolution: Repair any broken wiring or replace the control PCB if the door sensing circuit is damaged.
