Frigidaire Oven Error F30: What It Means & How to Fix It
Quick answer: F30 on a Frigidaire oven means the control board is reading an open or shorted circuit from the temperature sensor — it can no longer trust the signal, so it stops the bake or broil function as a safeguard.
“Oven threw F30 and wouldn’t bake at all. Vlad tested the sensor with a meter right in the kitchen, confirmed it was reading open circuit, and swapped it from parts on the truck. Baking again same afternoon.”
Quick Answer
The oven’s RTD sensor reports cavity temperature continuously so the board can cycle the heating elements correctly. F30 specifically means the reported resistance value is outside any plausible real-world range — not just “too hot” or “too cold,” but electrically broken. That distinction matters because it almost always points to the sensor or its wiring, not the heating element itself.
What Does F30 Mean?
A sensor that’s failed internally, or a connector at the back of the oven cavity that’s come loose or corroded, both produce the same open-circuit signature the board interprets as F30. It’s one of the more straightforward oven fault codes to diagnose because the sensor is a single, testable component.
4 Steps to Diagnose F30
Power off at the breaker and let the oven cool.
The sensor probe sits inside the cavity, usually top rear — don’t touch it while hot.
Locate the sensor and inspect its connector.
A small round probe on a wire, plugged into the back wall of the oven cavity. Check for a loose or corroded connection.
Test sensor resistance with a multimeter.
Compare the reading to Frigidaire’s spec for your model — a reading of zero or infinite resistance confirms sensor failure.
Replace the sensor if it fails the resistance test.
It’s a plug-in part on most models, though a technician can also confirm the wiring harness itself isn’t the culprit.
Can You Fix This Yourself?
Testing sensor resistance with a multimeter is a reasonable DIY diagnostic if you’re comfortable with basic electrical testing on a powered-off appliance. Replacing the sensor itself is often simple too — it’s usually a plug-in connector. If the resistance test comes back normal but F30 persists, that points to the control board, which is technician territory.

Frequently Asked Questions
Can I still use the oven with F30 showing?
No — the board has stopped trusting its temperature readings, so bake and broil functions typically won’t run at all until it’s resolved.
Will resetting the breaker clear F30?
Temporarily, if you’re lucky, but a genuinely failed sensor will trip the code again as soon as you try to bake.
Is a sensor replacement expensive?
It’s one of the less expensive oven repairs — the part itself is inexpensive, though labour depends on access on your specific model.
Can I test the sensor myself?
Yes, with a multimeter and the oven powered off. It’s a good first step before booking a repair visit.
