Oven displays F31; may occur intermittently with temperature swings.

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 insulation, Failed EOC sensor circuit

Safety First: Disconnect power at the breaker.

Inspect sensor and harness: Access the oven sensor and wiring. Look for melted insulation or wires touching metal.
Measure sensor resistance: At room temperature, the sensor should be ~1050–1100 Ω. A very low reading indicates a shorted sensor; replace it.
Check for shorts: With sensor disconnected, check each sensor lead to chassis ground with a multimeter. There should be no continuity. Repair any shorted wiring.
Control board: If sensor and wiring are good, replace the EOC.
