Possible Causes
Failed or weak thermal fuse/thermostat, Severe grease buildup restricting airflow, Fan not running at full speed, Incorrect replacement heater assembly
How to Fix / Troubleshooting
Safety first: Unplug and allow the unit to cool completely before opening.
- Clean thoroughly: Remove basket and drawer. Clean the cavity, heater guard, and fan shroud of grease and carbonized food. Use a non‑caustic cleaner and avoid soaking electrical parts.
- Check fan operation: Start a short cycle and listen for strong airflow. If airflow is weak or intermittent, inspect and replace the convection fan motor if necessary.
- Inspect thermal device: Access the heater bracket and locate the thermal fuse or thermostat. If it has partially failed, it may open prematurely. Test continuity at room temperature and after gentle warming (within safe limits). Replace if unreliable.
- Verify correct parts: If the heater or thermostat was recently replaced, confirm that the correct Morphy Richards‑specified ratings were used. Incorrect parts can cause nuisance overheat trips.
