Possible Causes
Open safety thermostat on top of oven cavity, Blown thermal fuse, Poor ventilation around built-in oven, Failed cooling fan causing overheating
How to Fix / Troubleshooting
Safety first: Disconnect power and wait until the oven is completely cool.
- Access the top of the oven: Remove the oven from the cabinet if necessary (support it properly). Remove the top cover to access the safety thermostat or thermal cut-out mounted on the top of the cavity.
- Check the safety thermostat: Many Candy ovens use a manual-reset thermostat (small button on top). Press the reset button firmly. If it clicks, it was tripped. Reassemble and test the oven.
- Test continuity: If there is no reset button, or it trips again, use a multimeter to check continuity across the thermostat or thermal fuse. Replace if open circuit.
- Inspect cooling fan operation: With the oven reassembled and power restored, start a low-temperature program and confirm that the tangential cooling fan (cabinet cooling fan) runs when the oven heats. If it does not run, check the fan motor and its wiring.
- Check ventilation: Ensure the oven has the clearances specified in the Candy installation manual. Blocked vents or tight cabinetry can cause repeated overheating.
If the thermostat continues to trip, there may be a deeper airflow or control issue that requires a technician.
