Kenmore F10 Error Code - Causes & Fix

Kenmore F10 Error Code — What It Means

The F10 code means the electronic oven control has detected a runaway temperature condition. The control believes the oven temperature has climbed above the setpoint in a way that signals an overtemperature fault, not just slow heating. This is a safety lockout to prevent actual overheating or fire risk.

In most cases the oven is not actually overheating. Instead, the control is seeing a faulty signal from the temperature sensor or a stuck relay inside the control board itself. The two most common root causes are a failed oven temperature sensor (probe) or a defective relay in the electronic oven control that is stuck closed and won’t stop sending power to the bake element.

Common Causes

• Failed oven temperature sensor The sensor resistance has drifted out of range or the probe has shorted, sending a false high-temperature signal to the control board.
• Stuck relay in the electronic oven control A relay on the control board has welded shut or failed closed, keeping power to the heating element even when the control tries to cycle it off.
• Damaged sensor wiring or connector The harness between the sensor and the control board has a short, open circuit, or corroded connector that creates an out-of-range resistance reading.
• Blocked oven ventilation Obstructed vents or a buildup of grease can cause genuine overheating, though this is less common than sensor or control faults.
• Defective electronic oven control board The main control board has failed internally, misreading sensor values or losing the ability to regulate temperature correctly.

Step-by-Step Fix

1. Disconnect power at the breaker or unplug the range, then wait at least 30 minutes for the oven cavity and all components to cool completely before you open any panels or touch wiring.
2. Inspect for obvious damage by looking at the oven temperature sensor probe (usually a metal tube mounted in the upper rear wall of the oven), its wiring, and all connectors for burn marks, melted insulation, or corrosion.
3. Test the temperature sensor resistance by unplugging the two-wire connector at the sensor, setting your multimeter to ohms, and measuring across the sensor terminals at room temperature (the sensor should read approximately 1,100 ohms at 70-75°F, with an acceptable range of roughly 1,080 to 1,100 ohms).
4. Replace the sensor if it reads below 1,000 ohms, above 1,300 ohms, open-line, or shows erratic jumps when you wiggle the probe or harness.
5. Check the sensor harness continuity if the sensor itself tests good by measuring from the sensor plug all the way to the control board connector to confirm the wires are intact and not shorted together.
6. Examine the control board for burnt relays, discolored solder joints, or heat damage around the oven relay positions, and replace the electronic oven control if the sensor and wiring both check out but the fault persists.
7. Restore power and test by running a bake cycle at a moderate temperature and watching for the F10 code to return or confirm that the oven now cycles normally.

Parts Often Needed

When to Call a Pro

Call a technician if you are not comfortable working with 240-volt appliance wiring or if you have already replaced the temperature sensor and the F10 fault returns immediately. Diagnosing a stuck relay or intermittent control-board fault often requires live voltage measurements and a clear understanding of the control circuit. A qualified appliance repair tech can also cross-reference your exact model and serial number to order the correct electronic control board the first time, since Kenmore ranges use many different board revisions and an incorrect replacement will not fit or communicate with your other components.
