F30
Frigidaire Oven
Severity: ModerateWhat Does This Error Mean?
F30 means the oven temperature sensor has an open circuit — it is either disconnected or has failed. The oven will not heat until the sensor is reconnected or replaced.
Affected Models
- Frigidaire Electric Range
- Frigidaire Gas Range
- Frigidaire Gallery Range
- Frigidaire Professional Range
- Frigidaire FGEF Series
Common Causes
- Open or failed oven temperature sensor (RTD probe)
- Disconnected or broken sensor wire connector
- Damaged sensor wire from heat or physical contact
- Control board unable to receive any signal from the sensor
How to Fix It
-
Reset the oven.
Turn off the circuit breaker for 5 minutes. If a loose connector was temporarily disturbed and reseated itself, the reset may clear F30.
-
Check the sensor wire connector.
The sensor probe is mounted inside the upper-rear corner of the oven cavity. Pull the range away from the wall and check the sensor wire connector at the back. Reseat it firmly.
-
Test the temperature sensor with a multimeter.
Disconnect the sensor and test resistance. At room temperature, Frigidaire sensors typically read around 1,100 ohms. A reading of infinite resistance (open) confirms the sensor has failed — replace it.
When to Call a Professional
Testing and replacing a Frigidaire oven sensor is a straightforward DIY repair. If F30 returns after a new sensor, a technician should check the wiring harness and control board.
