How to Fix / Troubleshooting
Safety warning: Unplug the microwave and do not operate with covers removed. Internal components can be hazardous.
- Check airflow: Ensure that intake and exhaust vents are not blocked by cabinets, wall, or debris. Clean any dust buildup on external vents.
- Listen for fan: When starting a cook cycle, you should normally hear the internal cooling fan. If it is silent or unusually loud before the error appears, the fan may be failing.
- Clean filters: On OTR models, remove and clean the grease filters. A clogged filter can reduce airflow and cause overheating.
- Professional inspection: Accessing the internal cooling fan requires removing the outer cabinet. The fan motor, wiring, and control board should be tested and replaced by a qualified technician if defective.
