What does F30 mean on a Frigidaire oven?

F30 means: Temperature sensor open. The most likely parts involved are RTD probe.

How much does it cost to fix F30?

A typical temperature sensor (rtd) replacement costs about $100–$250 nationally, parts and labor included. This is a reference range, not a quote — local prices vary.

Can I still use my oven with an F30 code?

Usually not. The oven typically stops heating because it can't measure its temperature. The cooktop may still work on some models, but the oven itself needs the sensor fixed first.

Why did F30 show up after a self-clean cycle?

Self-clean runs the oven very hot, which can strain an aging sensor or loosen its wire connection. A weak sensor often fails during or right after a cleaning cycle.

Frigidaire Oven F30 Error Code

Temperature sensor open

What's going on

F30 on a Frigidaire oven means the control board sees an open circuit in the oven temperature sensor, also called the RTD probe. The oven can't read its own temperature, so it usually stops heating to stay safe. The most common fix is replacing the sensor or repairing a loose connection to it.

Your oven uses a temperature sensor, a thin metal probe inside the oven cavity, to tell the control board how hot it is. The sensor's electrical resistance changes as the oven heats up, and the board reads that change to turn the heating elements or burner on and off.

When the board sees no signal at all, as if a wire were cut, it reads the sensor as open and shows F30. Without a working sensor the oven could overheat or not heat at all, so it shuts down baking and broiling until the problem is fixed.

Fault codes can differ between model generations. Check your model number, usually on a tag near the oven door frame or behind the storage drawer, to confirm what F30 means on your oven.

Likely causes

RTD probe — The sensor can fail inside, or its wire or plug connection can come loose or break, which looks like an open circuit to the control board. Heat over time and cleaning cycles can wear out the sensor or its connector.

The same code can mean different things on different model generations. Check the model number on your oven's rating plate before ordering parts.

Can you fix it yourself?

Doable for an experienced DIYer with the right part, but many people still call a technician.

Safe things to check first

Turn the oven off at the breaker for about a minute, then turn it back on. If F30 clears and stays gone, it may have been a one-time glitch.
Once the oven is cool and the breaker is off, look at the sensor probe inside the oven, usually near the top back corner. Check whether it is bent, damaged, or touching the oven wall.
Note whether F30 appears right away or only after the oven heats up or runs a self-clean cycle. That detail helps a technician narrow down whether it's the sensor or its wiring.
Unplug the oven or switch off its breaker before touching anything inside it, and don't remove any panels.

When to call a technician

A handy owner can often replace the sensor with the correct part for their model, but call a qualified appliance technician if the code keeps returning after a new sensor, or if you aren't comfortable working with the power off and wiring connections.

What the repair usually costs

$100–$250

Temperature sensor (RTD) replacement, parts and labor — national reference range

Confidence: low (based on a single cost guide — treat as a rough guide). Plus a service call fee of about $50–$100, often credited toward the repair.

This is not a quote. Prices vary by region and by model.

Repair or replace?

Repair usually makes sense. Even the high end of this repair stays under $480, about half the price of a typical new oven.

A typical new oven costs about $600–$1,300.
