Possible Causes
Open thermal fuse or high-limit thermostat, failed electronic oven control relay, missing L2 leg of power, burnt wire at terminal block
How to Fix / Troubleshooting
Safety: Disconnect power before testing continuity or removing panels.
- Check power: Verify 240 VAC at the terminal block. If only 120 VAC is present, one leg is missing and must be corrected at the breaker or supply.
- Test thermal devices: Locate any thermal fuse or high-limit thermostat in series with the elements. Test for continuity and replace any open device.
- Inspect wiring: Look for burnt or broken wires between the control and elements, especially near high-heat areas.
- Check control output: If power and safety devices are good, the control board may not be sending power to the elements and will need replacement.
