Frigidaire Oven: error code
What is this symptom?
If your Frigidaire oven displays an error code like F1, F2, or F3, it indicates an internal malfunction. These alphanumeric codes point to specific issues such as a faulty temperature sensor, a malfunctioning electronic control board, or communication errors between components. Understanding these codes can help you diagnose and address the problem effectively.
Important Tips for Frigidaire Models
- Frigidaire oven error codes follow consistent patterns where F3 typically means an open temperature sensor and F4 means a shorted temperature sensor. F1/F0/F5 indicate control board issues. Refer to model-specific technical sheets for exact ranges. (Frigidaire Appliance Support
Possible Causes
Temperature sensor (RTD) open or shorted
How to Identify: Error codes like F3 (open sensor or F4 (shorted sensor indicate the oven’s internal thermistor is not sending valid resistance data to the control board, often accompanied by incorrect temperature regulation. (frigidaireappliance.support
Part: Oven temperature sensor (RTD)
Electronic Oven Control (EOC) failure
How to Identify: Codes such as F0, F1, F5, and F6 often point to failed controls where resetting power does not clear the code. (frigidaireappliance.support
Part: Electronic Oven Control (EOC) / main control board
High oven temperature (thermal runaway)
How to Identify: F2 or F10 codes suggest the oven has exceeded safe temperature thresholds or detected runaway heating. (Frigidaire Owner Center
Part: Temperature control circuit / sensor
Door lock mechanism failure
How to Identify: Error codes in the F7–F9 or F90–F94 range often indicate problems during self-clean cycles where door lock operations fail. (Frigidaire Owner Center
Part: Oven door lock assembly or related switches
Communication error between components
How to Identify: Codes like F20 or combined F3/F20 indicate wiring or communication faults between sensor and control board. (Frigidaire Owner Center
Part: Control wiring / harness / interface connections
DIY Solutions
Inspect and Replace Temperature Sensor (RTD)
- Disconnect oven power at the breaker.
- Remove the rear panel to access the oven cavity sensor wiring.
- Visually inspect wiring to the sensor for damage and confirm connections are secure.
- Test RTD resistance with a multimeter.
- Replace the sensor if resistance is outside normal range and reconnect wiring.
Power Reset to Clear Transient Errors
- Turn off the oven at the circuit breaker.
- Wait 5–10 minutes to allow capacitors to discharge.
- Turn power back on and check if error code clears.
Next step

User Suggested Solutions
-
Check and replace the temperature sensor. First, unplug the oven. Locate the temperature sensor inside the oven, usually at the back wall. Disconnect it and use a multimeter to test for continuity. If faulty, replace it with a new one.
-
Inspect and replace the control board. Unplug the oven and remove the back panel to access the control board. Check for any visible damage or burnt components. If necessary, replace the control board with a compatible part.
-
Examine wiring and connections. Unplug the oven and check all wiring connections leading to the temperature sensor and control board. Look for any loose or damaged wires and repair or replace as needed.
