Possible Causes
Open bake element, Open broil element, Tripped thermal fuse or high-limit thermostat, Failed electronic oven control relay
How to Fix / Troubleshooting
Safety First: Turn off power at the breaker before testing elements or fuses.
- Test bake element: Remove the rear panel or access from inside the cavity. Disconnect the bake element leads and measure resistance (typically 15–40 Ω). Replace if open.
- Test broil element: Perform the same test on the broil element. Replace if open.
- Check thermal fuse: Locate the thermal fuse / high-limit thermostat on the rear of the oven cavity. Test for continuity; if open, replace and investigate causes of overheating (blocked vents, failed cooling fan).
- Control board: If all elements and fuses test good, the heating relays on the electronic oven control board may have failed and the board should be replaced.
