Frigidaire Oven Error Codes: F10, F11, F30, F31, F90 — Causes & Fixes
Frigidaire ovens and ranges display F-series error codes that range from minor inconveniences to situations requiring immediate action. F10 — runaway temperature — is the most serious and requires turning off the circuit breaker immediately. This guide covers the five most common Frigidaire oven errors with exact diagnosis and repair instructions.

Common Symptoms
- F-series error code on the oven display with beeping
- Oven overheating or not heating at all
- Self-clean door locked and won't open
- Keypad buttons unresponsive
- Oven starting on its own or not turning off
Most Likely Causes
- 1
F10 — Runaway Temperature / Thermal Overload
The oven has exceeded its maximum temperature limit (typically above 600°F when not in self-clean mode). The most common cause is a failed temperature sensor (RTD probe) sending incorrect low-temperature readings, causing the bake element to run continuously. This requires immediate action.
- 2
F11 — Shorted Keypad Key
One or more keys on the control panel are stuck in the 'pressed' position. Can be caused by moisture under the keypad, physical damage, or wear-induced keypad membrane failure.
- 3
F30 — Low Voltage on RTD Sensor Circuit
The oven temperature sensor (RTD probe) is reading lower than the valid range — usually an open circuit caused by a disconnected or failed sensor probe.
- 4
F31 — High Voltage on RTD Sensor Circuit
The temperature sensor is reading higher than the valid range — usually a shorted sensor or a short in the sensor wiring harness.
- 5
F90 — Door Lock Failure
The self-clean cycle cannot lock or unlock the oven door. The door lock motor, wiring harness, or door lock switch may have failed.

Quick DIY Checks
If your Frigidaire oven shows F10, turn off the circuit breaker immediately. F10 means the oven may be running the bake element at full power with no temperature control — this can cause a fire if left unattended.
Never attempt to service any oven component while the circuit breaker is on. Always disconnect power and allow the oven to cool to room temperature before touching internal components.
- 1For F10 — IMMEDIATE ACTION: Turn off the oven's circuit breaker immediately. Do not attempt to use the oven until the temperature sensor has been tested and replaced if needed. Allow the oven to cool completely before any inspection.
- 2Test the temperature sensor (RTD probe) for all F10/F30/F31 codes: Locate the sensor inside the oven cavity (a thin metal rod at the back, usually mounted with 2 screws). With the breaker OFF, unplug the sensor connector and test resistance with a multimeter — it should read approximately 1,080–1,100 ohms at room temperature (70°F). Any reading near 0 or OL (open) indicates a failed sensor.
- 3Replace the sensor: The RTD probe is held by 2 Phillips screws. Remove the screws, pull the probe out slightly, unplug the 2-wire connector, and install the new sensor. This is a 15-minute repair that costs $15–$30.

- 5For F90: Let the oven cool fully. Press Clear/Off and attempt to open the door. If the door stays locked, turn off the breaker, locate the door lock motor on top of the oven cavity, and manually slide the latch to release. Then test the door lock motor and switch.

Repair vs Replace
F10 and F30/F31 are almost always caused by a $15–$30 temperature sensor replacement — one of the easiest appliance repairs possible. Even an F11 keypad replacement ($60–$130) is well worth it. Only consider replacement if the control board itself has failed ($200+) on a unit over 12 years old.
Est. Repair Cost
$15–$150 (temperature sensor, keypad, or door lock)
Est. Replacement Cost
$900–$2,500 for a new Frigidaire range
