Frigidaire Oven F30 Error — Temperature Sensor Open

What it means

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.

Frequently Asked Questions

What is the difference between Frigidaire oven F10 and F30?

F10 means the sensor is shorted (reading falsely high — runaway temperature), while F30 means the sensor is open (disconnected or reading no signal at all). F10 is more dangerous; F30 simply prevents the oven from working.

How much does a Frigidaire oven sensor replacement cost?

Sensors typically cost $15–$40 and are one of the easiest DIY oven repairs. The sensor usually requires just one or two screws to remove from inside the cavity.
