Frigidaire oven — Error Code F10
Runaway temperature detected by the Electronic Oven Control (EOC).
What it means
The F10 error code on a Frigidaire oven indicates a 'Runaway Temperature' condition. The Electronic Oven Control (EOC) continuously monitors the oven cavity temperature via the RTD (Resistance Temperature Detector) sensor probe. If the EOC detects a resistance reading from the sensor that correlates to an unsafely high temperature—typically exceeding 650°F during a standard bake cycle—it triggers the F10 fault, sounds an alarm, and attempts to shut down the heating elements. This code is a critical safety mechanism to prevent overheating and potential fire hazards. The fault originates either from a genuine runaway heat situation (usually caused by a stuck relay on the EOC board continuously supplying L1 voltage to the bake or broil element) or a false reading caused by a defective RTD sensor probe or a short in the sensor wiring harness.
Likely Causes
- 1 Stuck Relay on the EOCA relay contact on the Electronic Oven Control board welds closed, sending continuous 240V to the bake or broil element regardless of the target temperature.
- 2 Faulty RTD Temperature SensorThe sensor probe resistance drifts out of spec, sending an artificially high temperature reading to the control board even when the oven is cool.
- 3 Shorted Sensor WiringDamaged insulation or a pinched wire in the sensor harness lowers resistance, mimicking a runaway heat condition to the EOC.
How to clear / reset
Because F10 is a critical safety fault, you must immediately disconnect power to the oven by flipping the dual-pole circuit breaker. Leave the power off for at least 15 minutes to allow the control board to reset and the oven cavity to cool. Restore power and press the 'Clear/Off' button. If the F10 code returns immediately at room temperature, you likely have a bad RTD sensor or a shorted EOC board. If it only returns after initiating a bake cycle and the oven visibly overheats, the EOC relay is stuck. The code cannot be bypassed without replacing the faulty component.
Common replacement parts
When to call a pro
Call a professional if a hard reset does not clear the F10 code, as diagnosing this requires testing live 240V circuits and measuring RTD resistance (which should be ~1080 ohms at room temperature). Replacing an EOC board involves transferring delicate wiring harnesses and ensuring proper grounding. Axis Appliance Repair offers a $90 diagnostic (waived upon authorized repair) and backs all control board and sensor replacements with a 1-year parts and labor warranty.
FAQs
How much does it cost to fix an F10 code?
If it is just the temperature sensor, expect repairs to run $150-$200 including labor. If the EOC board needs replacement, the total cost typically ranges from $300 to $500 depending on the specific board's availability.
Can I still use the oven with an F10 code?
No. The F10 code is a hard lockout for safety. Continuing to supply power to an oven with a stuck relay can cause extreme overheating, damaging the cavity or causing a fire. Keep the breaker off until repaired.
How do I test the temperature sensor?
Disconnect power, remove the sensor from the back wall of the oven, and test it with a multimeter. At room temperature (75°F), it should read approximately 1080 to 1100 ohms. If it reads open or significantly out of range, it must be replaced.
Will the F10 code clear itself once the oven cools?
If the code was triggered by a temporary glitch, a power cycle after cooling might clear it. However, if a relay is welded shut or the sensor is permanently out of spec, the code will return immediately upon power-up or heating.
How long does this repair take?
A professional technician can usually diagnose the exact cause in under 30 minutes. Replacing a sensor takes 15 minutes, while swapping and programming an EOC board takes about 45 minutes.
