Kenmore Oven F10 Error: Runaway Oven Temperature (Thermal Runaway)
The kenmore oven f10 error is a fault signal from the control board — this guide walks through what it means, common causes, and safe diagnostic steps. What Does Kenmore Wall Oven Error Code F10 Mean? F10 on a Kenmore 790-series wall oven (Frigidaire/Electrolux platform) means the oven has detected a thermal runaway condition — […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
No. F10 is a thermal runaway safety fault. Do not operate the Kenmore wall oven until the cause has been identified and repaired. A shorted relay will re-engage the heating element immediately on the next use, creating a fire hazard.
Can I reset the code?
No. Pressing Cancel or cycling the breaker may clear the F10 display temporarily, but if the bake relay is shorted or the RTD sensor is defective, the fault returns — and the underlying runaway condition continues to exist. F10 requires hardware repair before the oven is safe to use.
When to stop immediately?
Stop if you notice: F10 returns within one bake cycle after any reset, Oven exterior glass reaches a temperature that is uncomfortable to briefly touch during normal baking.
Symptoms You May Notice
Oven becomes excessively hot well above the set temperature
The oven interior climbs far beyond the temperature selected on the control panel — a 350°F bake setting may produce 500°F or higher inside the cavity — because the relay controlling the bake element has stuck closed, continuously powering the element without control board authorization.
F10 displayed on the control panel with an audible alarm
The Kenmore 790 control board sounds a continuous alarm tone and illuminates F10 on the display simultaneously with the safety shutoff, alerting the user that a thermal runaway event has been detected and stopped.
Oven door is hot to the touch on the exterior glass panel
Because the oven interior reached an abnormally high temperature before the board intervened, the outer door surface becomes warm or uncomfortably hot — a sign the cavity temperature far exceeded normal operating range.
Smoke or burning smell comes from the oven cavity
Before or alongside the F10 alarm, residue on oven walls begins to smoke and a burnt odor escapes around the door gasket, because the cavity has reached self-clean-level temperatures during a normal bake cycle.
Possible Causes
Shorted bake or broil element relay on the electronic oven control board
The relay on the ERC (electronic range control) that energizes the bake or broil element has failed in the closed position, allowing 240 V to continuously flow to the element even when the board has not commanded heating. This is the most common hardware cause of F10 on Frigidaire-platform Kenmore wall ovens.
Requires ProfessionalFailed oven temperature sensor (RTD probe) reading too low
If the RTD temperature sensor reports a resistance value significantly lower than actual oven temperature, the control board believes the oven is cooler than it is and continues heating. The board eventually detects the discrepancy via the safety limit and sets F10.
DIY PossibleFaulty electronic oven control (ERC) board
Internal failures of the ERC microcontroller or its relay driver circuitry can result in uncontrolled element activation that triggers F10 even when the RTD sensor is reading correctly.
Requires ProfessionalSafe Checks You Can Do

1
Cut power immediately and allow the oven to cool completely
If F10 appears while the oven is in use, turn the control knob or press Cancel/Off on the Kenmore 790 control panel. If the oven does not respond, turn off the wall oven circuit breaker in the home electrical panel. Do not open the oven door while the cavity is above-normal temperature — let it cool for at least 30 minutes with the breaker off before approaching.
Never leave a wall oven displaying F10 unattended even after pressing Cancel. The relay fault that caused runaway can re-engage the element immediately when power is restored if the relay remains shorted. Keep the breaker off until the cause is diagnosed.

Test the oven temperature sensor resistance at room temperature
Once the oven is completely cool and the breaker is off, locate the RTD temperature sensor — a slender metal probe inside the upper rear of the oven cavity, typically secured by two screws and connected to the control board via a two-wire harness. Disconnect the harness and measure resistance across the two sensor wires with a multimeter. At room temperature (approximately 70°F / 21°C), the RTD on Frigidaire-platform Kenmore 790 ovens should read approximately 1,080 to 1,100 ohms. A reading significantly lower than this range indicates a shorted sensor that could cause the board to over-heat the oven.
The RTD sensor for Kenmore 790 wall ovens is a standard Frigidaire part (most commonly 316217002 or equivalent). Sensor replacement is a safe DIY repair that clears F10 if the sensor is confirmed faulty — it does not require accessing the control board.
Tools required
When to Call a Professional
Contact a qualified technician if:
- RTD sensor resistance is within specification but F10 still sets during normal preheat — indicating a shorted relay on the ERC board
- F10 sets immediately when the oven is powered, before any bake command is issued — confirming the relay is stuck closed
- ERC board shows visible burn marks or failed relay solder joints on the rear of the board
