How to Fix / Troubleshooting

Safety: Unplug the microwave before any inspection. Do not operate the unit with suspected door switch faults.

Basic checks:

  • Open and close the door several times, listening for distinct clicks from the switches. A missing or weak click can indicate a faulty switch.
  • Check if the interior light turns off when the door is closed. If it stays on, a switch may be stuck.
  • Ensure the door is not warped or damaged.

Reset:

  • Unplug for 5–10 minutes, then plug back in and test. If E11 returns, a switch is likely defective.

Technician checks:

  • Test each door switch with a multimeter for proper open/closed operation.
  • Replace any switch with incorrect or intermittent readings.
  • Adjust the latch bracket so that switches actuate in the correct sequence.

Door switch replacement is moderately complex and should be done by someone familiar with microwave safety procedures.
