Kenmore Shorted Oven Temperature Sensor Circuit

Oven displays F4; may 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, Failed EOC sensor input

Safety first: Turn off power at the breaker.

Measure sensor resistance: Disconnect the oven temperature sensor and test with a multimeter. A very low resistance (near 0 Ω) indicates a shorted sensor; replace the oven temperature sensor.
Inspect wiring: Look for melted insulation or wires touching metal. Repair or replace damaged harness sections.
Replace EOC if needed: If sensor and wiring are good but F4 persists, replace the electronic oven control.
