Kenmore Oven F10 Error Code — What It Means
The F10 error code indicates that your Kenmore oven’s electronic control has detected a runaway temperature condition. This means the oven is heating outside the expected range, typically either overheating or the control board is receiving incorrect temperature readings from the sensor. The control shuts down the oven as a safety measure to prevent damage or fire.
This fault is usually caused by a problem in the temperature sensing circuit rather than an actual dangerous overheat. The control board monitors the oven temperature sensor continuously, and if it sees readings that suggest the oven is out of control, it triggers the F10 code and stops heating.
Common Causes
- Failed oven temperature sensor The sensor probe (RTD) has drifted out of specification or failed open or shorted, sending incorrect resistance values to the control board.
- Faulty electronic oven control board A stuck relay or failed sensing circuit on the main control board misreads normal sensor signals as a runaway condition.
- Damaged wiring or loose connectors Frayed, burned, or corroded wires between the sensor and control board cause intermittent or incorrect readings.
- Poor ventilation or blocked airflow Obstructions around the oven or blocked vents can trap excessive heat and trigger an overheat reading.
- Oven door not closing properly A warped or misaligned door allows heat to escape unevenly or interferes with normal temperature regulation.
Step-by-Step Fix
- Press OFF/CANCEL and then unplug the range or turn off the circuit breaker for 1 to 2 minutes to reset the control board, then restore power and check if the F10 code returns.
- Inspect the oven cavity and door to verify nothing is blocking airflow, the area around the range is clear, and the door closes and seals completely.
- Disconnect power at the breaker and access the oven temperature sensor, usually a metal probe extending into the rear or side wall of the oven cavity.
- Remove the sensor connector and use a multimeter set to ohms to measure resistance across the sensor terminals at room temperature (it should read close to 1,100 Ω at about 75 °F, and you should replace it if it reads below 1,000 Ω, above 1,300 Ω, or open).
- Check the sensor wire harness for continuity from the sensor connector to the control board plug, and inspect all wires and terminals for damage, burns, or corrosion.
- Replace the oven temperature sensor if it is out of the acceptable resistance range or if the wiring is damaged, then restore power and test the oven through a bake cycle.
- Replace the electronic oven control board if the sensor and all wiring test good, because a faulty relay or sensing circuit inside the control is likely causing the false F10 reading.
Parts Often Needed
| Part | Notes |
|---|---|
| Oven temperature sensor (temperature probe) | Amazon | Match the sensor to your Kenmore model number (typically a two-wire RTD rated around 1,100 Ω at room temperature). |
| Electronic oven control board (EOC) | Amazon | Also called the main control or clock/timer board. Verify the exact board part number for your model before ordering. |
| Sensor wire harness | Amazon | Only needed if wiring between the sensor and control is visibly damaged or burned. |
When to Call a Pro
Call a professional if you are not comfortable working with live electrical circuits or removing the range’s rear panel to access components. Multimeter testing is straightforward, but replacing the control board involves disconnecting multiple wire harnesses and mounting screws, and any mistake can damage the new board or create a shock hazard. If the F10 code returns immediately after a sensor replacement and all wiring checks out, the control board is the likely culprit and a technician can confirm the diagnosis and install the correct replacement part for your model.
