Possible Causes

Blocked airflow around magnetron, Failed magnetron cooling fan, Defective magnetron thermal cut-out, Overheating due to running empty

How to Fix / Troubleshooting

Safety: Unplug the microwave and allow it to cool for at least 30 minutes before inspection.

Steps:

  • 1. Avoid running empty: Never operate the microwave without food or liquid inside. Running empty can overheat the magnetron.
  • 2. Check ventilation: Ensure proper clearance around the unit and that vents are not blocked.
  • 3. Listen for cooling fan: During operation, you should hear the cooling fan. If not, the fan or its circuit may be faulty.
  • 4. Technician checks: A technician can test the magnetron thermal cut-out for continuity and inspect the fan and ducting for obstructions.

Resolution: Replace the magnetron thermal cut-out and/or cooling fan with the correct IKEA-compatible parts. If the magnetron has been repeatedly overheated, it may also need replacement.
