Princess Insufficient Cooling Airflow

Microwave runs but the fan seems weak and the exterior becomes very hot to the touch.

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

Partially blocked vents, Failing cooling fan motor, Dust buildup on fan blades and air channels, Incorrect installation with inadequate clearance

Safety: Unplug and allow the unit to cool before handling.

Clear surroundings: Ensure there is adequate space around the microwave as specified in the Princess manual (typically several centimeters on each side and above).
Clean vents: Vacuum or brush dust and grease from all external vents.
Listen to fan: During operation, you should hear a steady airflow. If the fan is very quiet or rattling, it may be failing.
Service: A technician may need to replace the cooling fan motor or clean internal ducts.
