Oven displays F31 and will not heat correctly.

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

Shorted oven temperature sensor, Sensor wiring shorted to chassis, Melted harness near hot surfaces, Failed control board sensor circuit

Safety first: Turn off power at the breaker before servicing.

Measure sensor resistance: Disconnect the sensor and measure resistance. A very low reading (near 0 Ω) indicates a shorted sensor; replace it.
Inspect harness: Look for melted or pinched wires between the sensor and control board. Repair or replace as needed.
Check at control: If the sensor is disconnected and the control still reads a short, the board is likely faulty and must be replaced.

Warning: Shorted sensor circuits can cause overheating; do not use the oven until repaired.
