GE Oven Error Codes: F3 and Other F-Codes Explained

GE oven error codes, the F-codes you see on a GE range or wall oven, are fault codes from the electronic oven control, and according to GE, F3 usually means the oven sensor needs to be replaced. A breaker reset sometimes clears a code; if it comes back, a trained service technician should diagnose it.

GE also says it cannot list every fault code for every past and present model, so check your owner's manual or GE's fault code page for yours.

Safety first: switch off the breaker before removing any panel, and never bypass or pry the door lock. We repair gas, electric and induction ovens; if you have a gas range and smell gas, leave the house and call 911 or your gas utility from outside.

How to reset a GE oven

GE says that shutting off the circuit breaker or fuse that powers the range or wall oven for a minute or two will sometimes clear the error. Step by step:

1. Turn the oven off and write down the code, along with the model and serial number.
2. Switch off the circuit breaker, or remove the fuse, that powers the range or wall oven.
3. Leave it off for a minute or two, then turn it back on.
4. If the code clears, watch the next few bakes. If it comes back, stop using the oven and book service.

If the code is F2 or the oven is hot, let it cool before the reset. If the door is stuck locked after self-clean, the door section below has GE's extra steps.

GE oven F3 error code

F3 (and F4): oven sensor

The oven sensor is the thin metal rod on the back wall inside the oven. It tells the control how hot the oven is. GE says F3 and F4 both usually mean the sensor needs to be replaced. A sensor that is drifting but has not failed outright can also make the oven run hot or cold without a code; see oven not holding temperature.

• Do the breaker reset above.
• If the code returns, stop using the oven and book a repair.

When to call a technician: F3 returns after the reset. Damaged wiring or a loose connector can throw the same code, so we test the sensor, its wiring and its connector before we quote a part. A sensor is one of the more affordable oven repairs.

Other GE oven F-codes

F1 (and F0, F6, F7): keypanel

GE says these usually mean there is a problem with the keypanel, the touchpad you press to set the oven, and that many times the keypanel needs to be replaced.

• Do the breaker reset.

When to call a technician: the code returns after the reset. The keypanel is replaced.

F2 (F20): oven too hot

GE says that for an unknown reason the oven temperature has exceeded a preset threshold.

• Turn the oven off and let it cool, then do the breaker reset.
• If the oven keeps heating with the controls off, leave the breaker off until it is repaired.

When to call a technician: always if F2 returns. A faulty sensor or a relay on the control that sticks on can let the oven run too hot.

F5, F8, FF: electronic control

GE says these usually mean the electronic control needs to be replaced.

• Do the breaker reset.

When to call a technician: the code comes back. Control boards are among the pricier oven parts, so we test the power supply and connections before we quote one.

F9 (and FC): door lock circuit

GE says these usually mean a component has failed somewhere in the door lock circuit, the lock that holds the door shut during self-clean.

• Do the breaker reset.
• If the door is stuck locked after self-clean, let the oven cool, then disconnect power for 30 seconds and see if it unlatches. GE's next step is to run self-clean again for 1 to 2 hours, wait about 30 minutes for the oven to cool and try the door again.
• Never force the door or pry the latch.

When to call a technician: the code or the stuck door persists. The lock motor, a lock switch or the wiring is replaced. Our guide to oven door locked after self-clean has the full routine.

FD: meat probe

GE says either the probe or the receptacle it plugs into may need to be replaced.

• Do the breaker reset.

When to call a technician: FD returns. Testing the probe and the receptacle shows which one has failed.

F350: cooling fan

GE says this points to an issue with the upper cooling fan circuit or something obstructing the cooling fan.

• Do the breaker reset.

When to call a technician: the code returns. The fan, its wiring or an obstruction behind the panels needs a technician. A noisy fan is often the first sign; see oven making noise.

F96, F97, F7X: internal component

GE says an internal component needs to be replaced. Try the breaker reset, and book service if the code comes back.

When any of these codes keeps returning, GE oven repair across the Atlanta area starts by confirming the code, then testing the part it names and the wiring to it.

Messages that are not F-codes

LOC DOOR flashing: control lockout

GE says that if LOC DOOR is flashing and you have not selected self-clean, the Control Lockout feature may be on. Not every model has the feature.

• Check your owner's manual for the pads that turn Control Lockout on and off.
• Make sure no one has started a self-clean cycle.

When to call a technician: only if the message will not clear once Control Lockout is off; GE's reset routine for this message is in its LOC DOOR article.

Bad Line: wiring

GE says Bad Line appears when power is applied to the unit but it has not been wired correctly. Leave the oven off and have the installer or a licensed electrician check the electrical hookup, especially on a new installation.

What usually fails

Most F-code repairs come down to one part: the oven sensor, the keypanel, the door lock assembly or the control board. Sensors and lock parts are straightforward; boards cost more. If your oven also runs cold or will not heat at all, see oven not heating up.

What it costs in Atlanta

For freestanding ranges and stoves, the diagnostic is $80 and repairs start at $180 plus parts. Built-in wall ovens and double ovens take more time to access, so the diagnostic is $120 and repairs start at $250 plus parts. On standard brands, typical all-in repairs run $230–$450 for a range and $330–$550 for a wall oven. The diagnostic is waived when you approve the repair, and you get a written flat-rate estimate before any work begins. Many GE oven repairs can be finished on the first visit when the part is in stock, and if a part must be ordered, there is no trip charge for the return visit. Every repair carries our 60-day parts-and-labor warranty. See our pricing.

Repair or replace?

F-code repairs are usually single-part fixes, and a wall oven is expensive to replace because it has to fit the cabinet. Repair almost always wins. Our repair-or-replace guide covers the exceptions.
