Possible Causes
Blown thermal cut-out (safety thermostat), Open main oven element, Faulty selector switch, Failed main relay on control board
How to Fix / Troubleshooting
Safety first: Turn off the oven at the mains and allow it to cool completely.
Step-by-step checks:
- 1. Verify mode selection: Ensure a valid cooking mode and temperature are selected and that the door is fully closed.
- 2. Check thermal cut-out: Access the rear or top of the oven to locate the safety thermostat. Test for continuity. If open and non-resettable, replace it with a genuine Hotpoint-Ariston safety thermostat.
- 3. Test main elements: Measure resistance of the lower and circular elements. Replace any open elements.
- 4. Inspect selector switch (if mechanical): Check for burnt contacts or loose spindles. Replace the function selector switch if contacts are damaged.
- 5. If all above are OK: Suspect a faulty main relay or control board and replace the main power module.
