A Kenmore oven displaying F30 typically has a failed temperature sensor probe or a broken wire in the sensor harness. In most service calls, replacing the oven sensor located in the back of the oven cavity fixes the problem immediately.
I've probably seen this code 200 times in the field. It's almost always a hardware failure, not a software glitch. The F30 means the control board can't see the temperature sensor at all, so the oven locks out completely until you fix it. Good news though: most of the time you're looking at a $20 sensor swap that takes maybe 20 minutes, and you're done.

What Does the F30 Code Mean?
OK so here's the deal with F30. Nine times out of ten it's just the sensor probe that's given up after years of heat cycles. A bad control board can technically cause this too, but I'd say I actually replace boards for F30 maybe once out of every fifteen calls. Always start with the sensor. It's cheap, it's easy, and you'll know within five minutes if that's your problem.

Symptoms You May Notice
F30 flashes on the display and the oven won't let you start any cook cycle at all, bake or broil, doesn't matter which you try.
You set the temperature, hit start, the oven just beeps at you and throws the code instead of preheating like it should.
Oven actually starts to preheat, gets maybe 50-100 degrees in, then shuts off and displays F30.
You unplug it, plug it back in, the code clears for about 30 seconds, then comes right back.
Intermittent F30 for a few weeks before it fails completely, usually a sign the sensor wiring is cracked and making contact sometimes but not others.
Can you reset a Kenmore oven to clear the F30 code?
Flip the breaker off and leave it for a full 5 minutes. Don't cheat and do 30 seconds. The control board has capacitors that need real time to fully discharge. Flip the breaker back on, wait for the display to come back up, and try starting a bake cycle. If F30 comes right back within a few seconds, the board's still seeing an open sensor circuit and you've got a physical repair to do.

Frequently Asked Questions
Can I still use the oven if it shows F30?
No, it won't let you. The board locks out bake and broil completely when it can't read the sensor. And honestly that's the right call, because without temperature feedback the oven has no idea how hot it's getting. It could run the element full blast and never know when to shut off. So it just locks down instead. You've got to fix the sensor before it'll let you cook anything.
Does an F30 error mean I need a new control board?
Almost never. I've been doing this 15 years and I'd say maybe 1 in 15 F30 calls actually ends up being a board. The sensor is the culprit almost every time. Buy the sensor first, it's like $20. If you put in a brand new sensor, verified all the wiring between the sensor and the board is intact, and you're still getting F30, then start thinking about the board. But don't jump to a $200 board when a $20 sensor is almost certainly your problem.
Why did my Kenmore oven sensor fail?
Heat stress, basically. Every time you turn the oven on and off, that sensor expands and contracts. Do that thousands of times over 7-10 years and the ceramic element inside the probe eventually cracks. Self-clean cycles are especially rough because they push temps up to 850-900°F. If your sensor died right after a self-clean, that's probably what finished it off. It's not a manufacturing defect, it's just wear. These sensors have a lifespan and yours hit it.
What should the resistance reading be on a Kenmore oven sensor?
Around 1080 ohms at room temperature. The full spec range is 1050 to 1100 ohms. If you're reading OL, meaning infinite resistance, the sensor is definitely dead. If you're reading something way below 1000 ohms, like 500 or less, that's a short and the sensor is also dead, just in a different way. Anything outside that 1050-1100 range and you need a new sensor. Don't overthink the measurement, it's either in range or it isn't.
Is the F30 error common on Kenmore Elite models?
Super common. A lot of the Elite line was manufactured by Frigidaire under the Kenmore badge, and they use the same sensor platform across a huge number of models. That sensor design is solid for about 7 years of normal use and then you start seeing them fail. I've had weeks where I replaced four or five of these on Kenmore Elite ranges in a row. It's not a lemon situation, it's just what happens when the sensor reaches end of life on a very popular platform.
How much does it cost to fix a Kenmore oven F30 error?
If you do it yourself, probably $20-35 for the sensor. Takes maybe 20-30 minutes once you've done it once. If you call a tech, figure $150-250 total with parts and labor. The part's cheap, the labor is what gets you. Honestly this is one of the better DIY appliance repairs out there because the sensor is so accessible and the test is simple. Meter reads OL, buy the sensor, swap it, you're done.
What part number do I need for the Kenmore oven temperature sensor?
Most Kenmore ranges on the Frigidaire platform use part number 316217002. But pull your model number first before ordering. It's usually on a label inside the oven door frame or on the storage drawer frame. Plug that model number into any appliance parts site and it'll confirm the right sensor for your specific unit. There are a few different connector styles and probe lengths out there, so don't assume the common part fits without checking.
