How to Fix / Troubleshooting

Safety: Unplug the microwave before accessing the fan area.

Steps:

  • 1. Listen to fan behavior: Note whether the fan never runs, runs all the time, or starts/stops erratically.
  • 2. Check vents: Ensure intake and exhaust vents are not blocked by cabinets, packaging, or grease buildup.
  • 3. Access fan (DIYers): Remove the outer cover and locate the cooling fan. Check that the blades spin freely and are not obstructed by insulation or wiring.
  • 4. Electrical test: With a multimeter, test the fan motor for continuity and verify that it receives voltage when the unit is running (for competent persons only).

Resolution: Replace the cooling fan motor if seized or open. If the motor is good but control is erratic, replace the main control PCB or fan relay with the correct IKEA-compatible parts.
