Frigidaire Oven F30 Error Code: Diagnostic and Repair Guide
Quick Answer
An F30 error means your Frigidaire oven has detected an open circuit in the temperature sensor. This usually happens because of a failed sensor probe or a loose wiring connection between the probe and the main control board.
Look, if you ignore this code and try to muscle through it somehow, you're flying completely blind. The oven literally can't tell if it's 200 degrees or 900 degrees in there, and that's how you get a fire. Nine times out of ten when I show up for this call, the sensor probe snapped internally from heat cycling and the fix takes about 20 minutes. Don't sit on this one.

What Does the F30 Code Mean?
Here's the deal with F30: it's basically your oven telling you it's lost contact with its own thermometer. The sensor probe costs $25-65 for most Frigidaire models, and swapping it out is honestly one of the easier appliance repairs you'll ever do. I've done probably 40 of these over the years. Cheap part, quick job, and 85% of the time the sensor itself is the culprit.
Most Likely Causes
Based on aggregated repair data, here is the probability breakdown for this error code:

Wiring harness or connector issues20%
Electronic control board failure5%
Symptoms You May Notice
F30 flashing on the display and it won't clear no matter how many times you hit Cancel.
Oven beeps repeatedly, usually three beeps at a time, like it's really trying to get your attention.
You set a bake temp, hit Start, and nothing happens. Oven just refuses to run.
It started a cycle, ran a few minutes, then shut itself off and threw the F30 code.
Code appeared right after a self-clean cycle finished or got interrupted mid-cycle and never went away.
Can you reset a Frigidaire oven to clear the F30 code?
Kill power at the breaker or unplug the range for a full 30 seconds. Plug it back in, then press Cancel or Off to clear the display. Set it to Bake at 350 to confirm it's working. If F30 comes right back, the board still can't see the sensor and something in the circuit is still open. Go back to step 3 and re-check your connections.

Frequently Asked Questions
What is an RTD sensor on a Frigidaire oven?
RTD stands for Resistance Temperature Detector. It's basically a precise thermometer that works by changing its electrical resistance as it heats up. At room temp it reads about 1080 ohms. At 350 degrees it reads higher, at 500 degrees even higher. The control board monitors that resistance constantly and uses it to decide when to cycle the heating elements on and off. When the sensor goes open circuit, the board has literally no idea what temperature the oven is, so it shuts everything down. Makes total sense when you think about it that way.
Can I still use my oven if the F30 code is flashing?
No, and don't try. The oven locks out the heating functions on purpose because without temperature feedback, the elements could just run full blast with no cutoff. That's how you start a fire. I know it's frustrating when you need to cook dinner, but this is one of those cases where the safety lockout is actually doing exactly what it's supposed to do. The fix is cheap and quick. Don't try to bypass it.
Why did my oven show F30 after a self-clean cycle?
Super common, I see this constantly. Self-clean runs at 900 to 960 degrees Fahrenheit, which is way hotter than any normal cooking temp and it's genuinely brutal on components. A sensor that was already getting weak might finally give up after that kind of heat. The plastic wiring connectors near the back can also melt or get brittle enough to crack. I always tell people: if you're going to run a self-clean, especially on an older oven, be mentally prepared for the possibility of a sensor replacement right after.
How much does it cost to fix an F30 error code?
DIY, you're looking at $25-65 for a replacement RTD sensor depending on your model. Pull your model number off the label inside the oven door frame and search for the specific part. Common part numbers across a lot of Frigidaire and Electrolux-built ranges include 316490000 and 316217002. If you hire a tech, budget $150-300 total for parts and labor. The job itself takes 20-30 minutes, so honestly you're mostly paying for the service call. It's a great DIY repair for a first-timer.
Is it possible the control board is causing the F30 code?
Yeah, it's possible, but it's maybe a 5% scenario. I've seen it twice in the last couple years, both times after power surges. Before you spend $150-200 on a control board, you need to confirm two things first: the sensor reads 1080-1100 ohms when tested directly, AND the wiring from the sensor all the way to the board connector is completely intact with no breaks or corrosion. Both of those need to check out clean before you point the finger at the board.
Can I test the sensor without fully removing it from the oven?
You can get a rough answer, yeah. Disconnect the sensor's wiring connector at the harness and put your meter leads on the sensor side pins while it's still mounted to the oven wall. You'll get a resistance reading that tells you if it's open or not. But honestly, pulling those two small screws to free it takes maybe 30 seconds and gives you a lot more to work with, including a visual check of the probe tip and the connector condition. Don't shortcut the visual inspection part.
