AEG Inadequate Ventilation or Cooling

Microwave exterior or control panel becomes very hot to touch during use.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Blocked ventilation openings, Failed cooling fan, Incorrect built-in installation, Continuous high-power operation

Safety warning: Excessive external temperature can damage electronics and cabinets.

Step 1 – Clear space: Ensure the microwave has the minimum clearance specified by AEG on all sides and top.
Step 2 – Check vents: Clean dust and grease from intake and exhaust vents.
Step 3 – Fan operation: Listen for the cooling fan during and after cooking. If silent, the fan motor may have failed and should be replaced.
