Oven overheats and burns food even at low temperature settings.
Safety Warning
This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.
If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.
Possible Causes
How to Fix / Troubleshooting
Safety first: Immediately switch off the oven and disconnect power. Do not continue using the oven until the fault is corrected.
Diagnosis:
- Test the temperature sensor for correct resistance; a very low resistance or short indicates failure—replace the sensor.
- Inspect the safety thermostat; if bypassed or incorrectly wired, restore proper wiring and replace any non-original parts.
- With power disconnected, inspect the control board for a welded heating relay; if suspected, replace the control module.
Because uncontrolled heating is a fire risk, if you cannot identify and correct the cause, contact a qualified technician before using the oven again.
