Possible Causes
Shorted temperature sensor, Stuck heating relay on main control board, Miswired power connection, Failed high-limit thermostat not opening at design temperature
How to Fix / Troubleshooting
Safety first: Turn off power immediately if the oven overheats. Do not continue using the oven until the fault is corrected.
- Test temperature sensor: Measure resistance at room temperature. A significantly low reading indicates a shorted sensor; replace it.
- Check control relays: With power disconnected, inspect the main control board for welded or burned relays. Replace the board if any relay appears damaged.
- Verify wiring: Ensure that the oven is wired according to the installation diagram, with correct line and neutral connections. Incorrect wiring can bypass control circuits.
- High-limit thermostat: Test the high-limit thermostat for proper operation. If it remains closed even at excessive temperatures, replace it.
