F2 code on GE oven: what it means and what to check
A GE oven showing F2, or F20 on some models, is warning that the control thinks the oven got too hot. This page explains what you can check safely from the front of the oven, when to shut it off at the breaker, and what a technician tests next.

The F2 code on GE oven means the control has sensed an over-temperature condition, often called runaway heat, or on some models F20. The most common part-level cause is the oven temperature sensor circuit, especially a sensor or connector adding too much resistance.
Check these first
Safe to do yourself. Unplug the appliance before you start.
- Turn the oven off if it is still heating
Press Clear or Off. If the bake or broil element keeps heating, or food is burning fast while the oven is supposed to be off, shut off the breaker and stop using the oven until it is checked.
- Let it cool fully
F2 can appear during or after self-clean because that cycle runs extremely hot. Let the oven cool before trying to open a locked door, and don't force the door open while it is hot.
- Reset the control
Turn power off at the breaker for a few minutes, then restore power. This can clear a one-time control fault, but a code that comes back needs diagnosis.
- Check for blocked oven vents
Look for foil, pans, grease, or heavy soil blocking the oven vent path. Clean visible grease from the oven cavity and vent area with the power off, then try a normal bake cycle only if the oven cooled and the code cleared.
- Note when the code appears
F2 during normal bake points hard at the sensor circuit or control. F2 with the oven off in clock mode, or heat that won't shut down, points more toward the electronic range control.
Conditions that make this more likely
Boards fail earlier in hot rooms
Electronics are rated for room temperature. In a garage or an unconditioned laundry room in summer, a control board can sit well above that for hours a day. Before replacing a board, a good technician confirms the parts it controls test good, since a shorted pump or valve can take out a new board too.
Lint and dust build up faster than you'd think
Dryer vents, refrigerator condenser coils and dishwasher filters collect lint, pet hair and dust. Homes with pets, long vent runs or dusty surroundings usually need these cleaned more than once a year.
What a technician tests
Most likely part first. These are for a technician with a meter and the tech sheet, not a weekend project.

Can I reset a GE oven F2 code?
Yes. Turn the oven off at the breaker for a few minutes, then restore power after the oven has cooled. If F2 returns, keep resetting out of the routine because it is a safety fault.
Is F2 the same as an oven calibration problem?
A small temperature offset can be calibration. F2 means the control believes the oven reached an unsafe temperature, so the sensor circuit, relay, airflow, or control board needs to be checked.
Why did F2 show up after self-clean?
Self-clean runs at very high heat, so a weak sensor connector, cooling fan issue, or control board can show up during that cycle. Let the oven cool fully and avoid self-clean again until the fault is diagnosed.
Can I use the cooktop if the oven has F2?
On a range, the surface units may still work, but leave the oven off. If the oven heats when it should be off, shut off the breaker and arrange service before using the appliance again.
Is this covered by warranty?
Check the model, serial tag, and purchase date before authorizing a repair. A repair company can still diagnose the fault, but manufacturer coverage decisions come from GE or the seller.
