How to Fix / Troubleshooting

Danger: A microwave that runs with the door open is unsafe. Unplug it immediately and do not use it until repaired.

Steps (for experienced DIYers):

  • 1. Inspect door switches: With the unit unplugged, remove the outer cover and control panel to access the door switch cluster. Check for burned or melted switches.
  • 2. Check alignment: Ensure the latch bracket is not bent and that the door hooks fully actuate the switches.
  • 3. Replace switches: Replace any switch that appears damaged or tests incorrectly with a multimeter.

If you are not experienced with appliance repair, have a technician correct the door interlock system. Do not operate the microwave until this is fixed.
