Frigidaire Ovens & Ranges F10 Error Code (Runaway Temperature): How to Fix It Yourself
The F10 error on a Frigidaire oven means the control board detected a runaway oven temperature — the oven is either too hot or the sensor is giving a bad reading. This is a safety alert, so take it seriously. The good news is that 70% of the time it is just a bad temperature sensor (a cheap and easy fix). The other 30% of the time it is the control board.
⚠️ Safety First
- Turn off the oven at the circuit breaker immediately when you see the F10 error — the oven may be overheating.
- Do not use the oven until the problem is fixed — a runaway temperature is a fire risk.
- Let the oven cool completely before working on it.
- Electric ovens use 240 volts — always verify the breaker is off with a multimeter.

Step-by-Step Repair
- 1
Turn off the breaker immediately
Do not just press Cancel — turn off the circuit breaker for the oven. The F10 error means a potential overheat condition. Cutting power at the breaker ensures the heating elements cannot energize.
- 2
Let the oven cool and then reset
Wait 30 minutes for the oven to cool down completely. Turn the breaker back on. If the F10 error comes back immediately (even with the oven at room temperature), the temperature sensor is probably giving a false reading. If the error only appears when the oven is heating, the sensor or control board may be failing under heat.
- 3
Test the temperature sensor
Turn the breaker off. Find the temperature sensor — it is a thin metal probe sticking into the oven cavity from the back wall, near the top. Disconnect the wire harness at the back of the range. Set your multimeter to resistance (ohms) and measure across the two sensor terminals. At room temperature, it should read around 1080–1100 ohms. If you get an open circuit (no reading) or a wildly different number, the sensor is bad.

Replace the temperature sensor if faulty
With the breaker off, remove the mounting screw from the back of the range. Gently pull the old sensor out through the back wall. Disconnect the plug. Connect the new sensor, slide it into the oven cavity, and secure the screw. This takes about 5 minutes.
- 5
Test after replacing the sensor
Turn the breaker back on and set the oven to 350°F. Monitor it with an oven thermometer. If it heats normally and the F10 error does not return, you are done. Let it run for 15–20 minutes to be sure.
- 6
If the sensor was fine, check the control board
If the sensor tested at the correct resistance but the F10 error persists, the oven control board (EOC — Electronic Oven Control) is likely faulty. The control board is behind the control panel at the top of the range. Replacing it involves disconnecting several wire harnesses and swapping the board. Take photos of every connection before disconnecting.
- 7
Replace the control board (if needed)
Turn the breaker off. Remove the screws from the back cover of the control panel area. Carefully photograph all wire connections. Disconnect each harness from the old board. Remove the mounting screws. Install the new board, reconnect everything exactly as it was, and reassemble. Turn the breaker on and test.
If That Didn't Work
- Wiring issue between sensor and control board
- Relay stuck closed on the control board (sending continuous power to element)
- Intermittent sensor connection
When to Call a Professional
If the temperature sensor tests good, the control board is likely the issue. The control board is expensive ($80–$200) and if you install a new one and it was not the problem, you are stuck with it. A tech can diagnose which part has failed with certainty. Expect to pay $150–$350 for a tech to diagnose and replace the right part. Given that the F10 is a safety issue, do not use the oven until it is fixed.
