Frigidaire Oven F10 Error: What It Means & What to Do
F10 is the one Frigidaire code you shouldn't shrug at. Frigidaire's own label for it is thermal runaway: the electronic oven control believes the oven is heating past its set point and has stepped in.
Sometimes the oven really is overheating. Sometimes a temperature sensor is lying to the board. Either way, don't cook on it until it's sorted.
If F10 shows up while the oven is on
Turn the oven off at the controls. If the controls won't respond, or you can feel it still heating, shut it off at the breaker. A relay on the control board can weld closed and keep the bake element powered no matter what the display says, which is exactly the situation F10 exists to catch.
Frigidaire's first step for an F10 is a reset: cut power for about 30 seconds by unplugging the range or flipping the breaker off and back on. If the code returns, or shows up while the oven is off and just displaying the clock, Frigidaire's guidance is to book service (or go back to your installer if the range is under 30 days old).
What causes it
- The oven temperature sensor (an RTD probe at the back of the cavity) has drifted out of range. This is the most common cause.
- A wiring harness or connector between the sensor and the control has corroded, chafed, or come loose.
- The electronic oven control (EOC) itself has failed, or its bake relay has stuck closed so the element never cycles off.
How it's diagnosed
The sensor has a known resistance. On Frigidaire and Electrolux ranges it reads roughly 1080 to 1100 ohms at room temperature and climbs as the oven heats. A technician measures it first at the control board connector. If the number is wrong there, they measure again right at the sensor. The same wrong reading at both ends means the sensor is done. A correct reading at the sensor but a wrong one at the board means the harness between them is the problem. Correct readings at both ends with the oven still running away points at the control.
A real example of why that order matters: one owner reported a sensor that read a healthy 1080 ohms at the probe but nonsense at the control plug. The sensor and board were fine. The harness had failed, and splicing in high-temperature wire fixed it.
One more clue: if F10 appears with the oven off and the display just showing the time of day, the control board is the usual culprit, because nothing else is running.
Repair or replace
A sensor is an inexpensive part and a quick job. A harness repair is similar. An electronic oven control on an older range can cost a meaningful fraction of a new stove, and on some discontinued models the board is no longer available.
