Frigidaire oven — Error Code F10
The Electronic Oven Control (EOC) has identified a runaway temperature condition.
What it means
An F10 error on your Frigidaire unit signals a 'Runaway Temperature' issue. The Electronic Oven Control (EOC) keeps a constant watch on your oven's interior heat by reading data from the RTD (Resistance Temperature Detector) sensor probe. If the EOC interprets the resistance data as a temperature exceeding safe limits—usually over 650°F during standard operation—it throws the F10 code, triggers a warning tone, and attempts to cut power to the heating elements. This is a vital safety feature designed to prevent fire or extreme heat damage. The fault is usually triggered by an actual overheating event caused by a welded relay on the EOC board that keeps the bake or broil element powered, or by an inaccurate signal from a failing RTD sensor or damaged wiring.
Likely Causes
- 1 Stuck Relay on the EOCA relay on the Electronic Oven Control board has fused shut, causing a constant 240V supply to the bake or broil element regardless of the selected temperature.
- 2 Faulty RTD Temperature SensorThe resistance in the sensor probe has drifted, causing it to report an inaccurately high heat level to the control panel even when the oven is cold.
- 3 Shorted Sensor WiringA pinched wire or damaged insulation within the sensor harness drops the resistance, which tricks the EOC into thinking the oven is in a runaway heat state.
How to clear / reset
Because the F10 code is a safety lockout, you must immediately kill power to the appliance by flipping the dedicated dual-pole circuit breaker. Keep the power off for at least 15 minutes to let the control board reset and the oven interior to reach a safe temperature. Once you flip the breaker back on, hit the 'Clear/Off' button. If the F10 code reappears while the oven is cold, the RTD sensor or the EOC board is likely faulty. If the code only pops up after you start a bake cycle and the oven begins to overheat, the EOC relay is stuck. You cannot bypass this code; the broken part must be replaced.

When to call a pro
Reach out to us if a hard reset fails to clear the F10 alert. Diagnosing this requires checking live 240V circuits and verifying RTD resistance, which should be roughly 1080 ohms at ambient temperature. Swapping an EOC board requires careful handling of sensitive wiring and ensuring proper grounding. A-Fix Service provides a $90 diagnostic fee (waived if you proceed with the repair) and guarantees all control board and sensor replacements with a 1-year parts and labor warranty.
FAQs
What is the typical cost to repair an F10 error?
For a simple temperature sensor replacement, expect to pay between $150 and $200 including labor. If the EOC board requires swapping, the total cost usually lands between $300 and $500, depending on the specific part availability.
Can I keep using my oven while the F10 code is active?
No. The F10 is a hard safety lockout. Using an oven with a stuck relay is dangerous, as it can lead to severe overheating, damage to the oven cavity, or a fire. Leave the breaker off until a professional can fix it.
What is the procedure for testing the temperature sensor?
Shut off the power, detach the sensor from the back of the oven interior, and measure it with a multimeter. At room temperature (75°F), the reading should be about 1080 to 1100 ohms. If it shows an open circuit or is way off that range, you need a new one.
Will the F10 code reset once the oven cools down?
If the error was caused by a minor glitch, a power cycle after cooling might work. However, if a relay has welded shut or the sensor is permanently damaged, the error will return as soon as you restore power or try to heat the oven.
How much time is required for this repair?
A qualified technician can usually pinpoint the issue in less than 30 minutes. Replacing a sensor takes roughly 15 minutes, while swapping and configuring an EOC board takes around 45 minutes.
