A GE oven F2 error means the unit is overheating or thinks it is overheating. In most service calls, this is caused by a faulty oven temperature sensor or a stuck relay on the electronic control board that prevents the heating element from turning off.
Look, F2 isn't a code you mess around with. It means your oven thinks it's on fire, basically. I've seen this come in right after self-clean cycles more times than I can count, and half the time the oven really is running way too hot because a relay on the board is welded shut. Don't just reset it and cross your fingers. Test the sensor, check the wiring, and if those pass, that board needs to come out.

What Does the F2 Code Mean?
OK so here's the deal with F2 on a GE oven. You're either looking at a $50 sensor fix or a $300 control board, and the only way to know which one is to actually test the sensor resistance with a multimeter. If you just ran self-clean, that probably tripped it. GE ovens are pretty well-built overall, but their RTD sensors don't love the 900-degree temps that self-clean hits, and the board relays aren't crazy about it either.

Symptoms You May Notice
The oven temp shoots way past your setpoint. You ask for 350 and an oven thermometer is reading 450, 500, still climbing.
The bake element or broil element glows red and stays glowing even after you push the off button, or stays on with the door open.
F2 flashes mid-cook with a loud alarm and the oven goes completely unresponsive until you cut the breaker.
You try to start the oven and it throws F2 within the first 30 seconds, before it's even had a chance to actually heat up.
After a self-clean cycle the oven locks up and displays F2 once it cools down, and it won't clear even after you cycle the power.
Can you reset a Ge oven to clear the F2 code?
Go to your electrical panel and flip the oven breaker to off. Don't just unplug it at the wall outlet if it's hardwired, you need the breaker. Leave it off for at least 5 minutes so the capacitors on the board fully discharge. Flip it back on, wait for the display to boot, then set a short 300-degree preheat and watch it for 10 minutes. If F2 comes back during that test preheat, there's a hardware failure that a reset won't fix.

Frequently Asked Questions
Can a self-clean cycle cause an F2 code?
Yeah, it's honestly the most common trigger I see. Self-clean runs the oven up to around 900 degrees for 3-4 hours straight, and that extreme heat stresses everything on the circuit. The RTD sensor probe can fail from the sustained heat, the solder joints on the relay contacts can reflow and fuse together, and the wire harness insulation sometimes cracks near the back wall where it's hottest. If your F2 showed up right after self-clean, check the sensor first. Odds are good it's either the sensor or a welded relay on the board.
Is it safe to keep using the oven if the F2 code only happened once?
Honestly, no. Don't do it. F2 means your oven either overheated or is about to, and an oven that overheats without shutting off is a real fire risk. I've seen situations where the thermal fuse was the only thing that finally cut power after a relay failed. That thermal fuse is a one-shot deal too, once it blows it's blown. At minimum, run the sensor resistance test before you use it again. Takes 10 minutes and tells you a lot.
How much does it cost to fix a GE F2 error?
If it's the sensor, you're looking at $40-90 for the part depending on your model, plus maybe an hour of your time. Super reasonable fix. If it's the main control board, budget $200-400 for the part alone, and installation can add another $100-150 if you're paying a tech. On older ovens worth $500 or less, a $350 board repair is a tough call. I usually tell customers if the oven is over 12 years old and needs a board, start shopping for a replacement.
Why does the F2 code appear when the oven isn't even on?
That's almost always a shorted temperature sensor or a short somewhere in the sensor wiring. Here's why: the control board monitors sensor resistance constantly, even with the oven off. A shorted sensor reads near zero ohms, and the board interprets that as a temperature way above the safe limit. So it fires the F2 alarm even at room temperature. Disconnect the sensor connector and check the resistance at room temp. If it reads a lot lower than 1080-1100 ohms, you found your problem.
What's the difference between F2 and F3 on a GE oven?
F2 means over-temperature, the oven is too hot or thinks it is. F3 is basically the opposite, it means the sensor is open circuit and the board can't get any reading at all. Both codes usually point to a bad temperature sensor, which is why I always test the sensor first on either code. The multimeter reading tells you which way it failed: too low resistance equals F2 territory, open circuit equals F3 territory. Same $50-90 part either way.
Can I replace just the relay instead of the whole control board?
Technically yes, if you're comfortable with a soldering iron and reading circuit board component specs. The relays are usually standard SPDT 30A relays you can find for a few dollars. But practically speaking, most homeowners shouldn't try it. If you desolder the relay wrong you can lift a pad and trash the board completely. Most techs just swap the whole board because it's faster and comes with a warranty. If you're handy with electronics though, it's absolutely a valid repair and saves real money.
