Kenmore Oven F30 Error Code: Lower Oven Sensor Open

Quick Answer

Kenmore F30 is specific to double oven models manufactured by Frigidaire (790-prefix Kenmore). It means the LOWER oven temperature sensor has an open circuit. The upper oven has its own sensor with a different code (F3).

This one catches people off guard because most Kenmore owners don't know they've got a Frigidaire inside. If you ignore F30, the lower oven stays locked out completely. Can't bake, can't broil. I've seen folks wait thinking it'll clear itself and it never does. The board needs a live resistance reading from that lower sensor to run. No signal, no heat. Usually a $20 fix if you catch it early.

What Does the F30 Code Mean?

Here's the deal with this code: Kenmore doesn't actually make ovens. Your 790-prefix model was built by Frigidaire, and F30 is straight out of their playbook. The lower oven's temperature sensor has gone open circuit, meaning the board's sending out a signal and getting nothing back. It's a safety thing. The oven won't run blind. I've fixed probably a dozen of these. Usually a sensor swap and you're done in under an hour.

Symptoms You May Notice

F30 flashing or solid on the display with an alarm beeping, usually the second you try to start a bake cycle in the lower oven.
Lower oven completely dead and won't heat at all, even though the upper oven on your double oven works just fine.
The oven starts preheating, then suddenly cuts off and throws the code mid-cycle before it ever hits your target temp.
Clock and display still work, controls respond, but you literally cannot get the lower cavity to do anything.

Can you reset a Kenmore oven to clear the F30 code?

Kill power at the breaker for a full 60 seconds. Don't cheat and just flip the oven's control off. After 60 seconds, flip the breaker back on and try a bake cycle. If F30 comes right back, the board's confirmed something's physically broken in that sensor circuit and a reset won't fix it. But if it was a one-time voltage blip, it'll clear and you're done.

Frequently Asked Questions

Is my Kenmore oven made by Frigidaire or Whirlpool?

Easiest way to tell is the first three digits of your model number. A 790 prefix means it was manufactured by Frigidaire (sold under the Electrolux umbrella), which is exactly where the F30 code comes from. If you see 665 or 106, that's a Whirlpool-built unit. Knowing this upfront is the whole ballgame because it tells you which wiring diagram to pull and which parts actually fit your oven.

How much does fixing a Kenmore F30 usually cost?

If you're doing it yourself, a new lower sensor usually runs $20 to $50 depending on your model. If you're calling a pro, expect a diagnostic fee plus labor, which typically lands somewhere between $175 and $275 all-in. Honestly it's almost always worth fixing. These 790-series Kenmores are workhorses. I've got customers still running them after 20 years with nothing more than a sensor here and a bake element there.

Can I use Frigidaire parts in my Kenmore 790 oven?

Yeah, absolutely. Because Frigidaire built these units for Kenmore, the parts are identical. If you order an OEM Kenmore sensor, it'll often arrive in an Electrolux or Frigidaire branded bag anyway. Just match the part number to your specific 790-prefix model number to make sure you get the right harness length. The sensor element itself is usually the same across a wide range, but the connector pigtail length can vary a couple inches between generations.

Can I still use the upper oven while F30 is showing?

Yeah, on most 790-series double ovens you can. F30 is specifically the lower cavity sensor, so the upper oven should still function normally. The two cavities have separate sensors and separate control circuits. I'd still get the lower one fixed soon though, don't let it sit for months because moisture can keep working its way into a damaged connector and make the repair messier. But if you need to cook dinner tonight, the upper oven's fair game.

What's the part number for the lower oven sensor on a 790 Kenmore?

The most common replacement is Frigidaire part 316490001. That fits a huge range of 790-series Kenmore double ovens. Before you order, search your full model number on a parts site to confirm, because the wire harness length can vary slightly between generations and you don't want to come up two inches short. I've ordered the wrong harness length exactly once. The sensor probe itself is almost always the same, but always verify before you hit buy.
