How to Fix / Troubleshooting
Safety first: Unplug the microwave and let it cool completely.
- Check installation: Ensure the Telefunken combination microwave has the clearances specified in the manual, especially at the rear and top.
- Inspect convection fan: Remove the rear or top cover to access the convection fan. Check that it spins freely and is not obstructed by foil, packaging, or debris.
- Test thermal cutouts: Locate the thermal cutouts near the grill and convection heater. With power disconnected, test for continuity. Replace any open (non-resettable) cutouts with identical-rated parts.
- Replace fan motor if needed: If the fan does not run during a convection cycle, test and replace the fan motor.
