Telefunken Inadequate Ventilation / Cooling Failure

Microwave exterior (top or sides) becomes excessively hot to the touch during normal 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 external vents, Failed cooling fan motor, Installation in confined cabinet without proper clearances, Dust buildup on vents and fan

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

Check clearances: Ensure the Telefunken microwave has the minimum space around it as specified in the manual.
Clean vents: Use a vacuum or soft brush to remove dust from all external vents.
Verify fan operation: During a short heating cycle, listen for the cooling fan. If it does not run, the fan motor or its wiring may be faulty and should be replaced.
Reinstall correctly: If built-in, confirm that the trim kit and cabinet cutout allow proper airflow.
