Possible Causes
Blown non-resettable safety thermostat, Repeated overheating due to blocked vents, Failed cooling fan causing high cabinet temperature, Loose connection on thermostat terminals.
How to Fix / Troubleshooting
Safety first: Disconnect the oven from the mains power supply. Surfaces may still be hot.
Steps:
- Check ventilation and fan: Ensure all vents are clear and the cooling fan operates when the oven is on.
- Locate safety thermostat: This is typically mounted on the top or rear of the oven casing, separate from the cavity thermostat.
- Test continuity: Disconnect the wires and test with a multimeter. An open circuit reading indicates it has blown.
- Replace thermostat: If it's a non-resettable type, replace the high-limit safety thermostat with the exact Morphy Richards-specified part.
- Investigate cause: Check for a failed cooling fan or blocked vents that may have caused the overheating.
Warning: Never bypass or short-circuit the safety thermostat; this is a critical safety device.
