Possible Causes
How to Fix / Troubleshooting
Safety: Excessive cabinet heating can be a fire risk. Stop using the microwave until installation is verified.
User checks:
- Review the SMEG installation manual to confirm that the correct cut-out dimensions and ventilation openings have been provided.
- Ensure that decorative panels or trim kits are correctly installed and not blocking vents.
- Check for items stored in adjacent cabinets that may be blocking airflow.
If installation appears incorrect, consult a professional installer or SMEG service to correct the cabinetry and ventilation. If installation is correct but heating persists, the internal cooling system should be checked by a technician.
