Possible Causes
Defective high-limit thermostat, Faulty cavity temperature sensor, Loose sensor wiring, Control board misreading sensor
How to Fix / Troubleshooting
Safety first: Disconnect power before accessing internal components.
- Locate high-limit thermostat: Typically mounted on the oven cavity or rear panel. Test for continuity at room temperature; it should be closed. Replace if open.
- Check cavity sensor: Test the oven temperature sensor resistance (~1080–1100 Ω at room temperature). Replace if out of spec.
- Inspect wiring: Ensure all sensor and thermostat connections are secure and wires are not damaged.
- Control board: If all sensors and thermostats test good, the control board may be faulty and require replacement.
