How to Fix / Troubleshooting

Safety first: Unplug the microwave and allow it to cool.

  • Check clearance: Ensure there is sufficient space around the Ambiano microwave as specified in the manual (typically several centimeters on all sides and top).
  • Clear vents: Remove any objects blocking the vents. Clean dust and grease from vent openings.
  • Inspect cooling fan: Remove the outer cover and verify the fan runs whenever the microwave is operating. Replace the fan motor if it does not run or is very weak.
  • Usage pattern: Avoid running the microwave continuously for long periods. Allow short cooling intervals between long cycles.
