GE Oven & Range F350 Error Code: Meaning, Causes & Fix
Upper cooling fan circuit fault, or an obstruction in the cooling fan — GE's published definition for F350 on its newest oven controls.
GE's own fault-code list defines F350 plainly: there is a problem in the upper cooling fan circuit, or something is obstructing the cooling fan. The cooling fan is the fan that pulls air across the control and electronics area (and around the cavity on many built-in and self-clean models) to keep the electronics from cooking themselves. The control watches that circuit; when the fan does not run, runs out of its expected range, or its circuit reads open or shorted, the control sets F350 and will typically refuse heating cycles until the fan story is resolved. The code belongs to the extended three-digit F3xx format GE's newest controls use, and it is a fan code — not a temperature-sensor code, despite sitting numerically near the F3 sensor family. F350 rewards being read as GE wrote it: 'an issue with the upper cooling fan circuit or an obstruction in the cooling fan'. Note the two branches GE itself offers — the circuit, or something physically in the fan's way — because they split the owner's work cleanly. The obstruction branch is the only branch an owner can fully clear from outside the appliance, and GE lists it because it genuinely happens: the cooling fan moves air across the electronics bay and around the cavity shell, and its intake and exhaust paths pass exactly the places kitchens store things and foil migrates. The circuit branch — motor, connector, harness, the control's output to them — is diagnosed by behaviour: whether the fan runs at all, whether it runs when cold and stops when hot, and whether the code is present from power-on or only earned after hard use. Keep those two branches separate and F350 is one of GE's more honest codes; merge them and owners end up buying fan motors for blocked vents.
What causes the F350 code on a GE oven & range?
An obstruction in the cooling fan
Foil, a displaced piece of insulation, a pan stored against a vent, or debris drawn into the fan housing can stall the fan or slow it below what the control expects — GE lists obstruction first for a reason.
The cooling fan motor itself has failed
Fan motors seize or open electrically after years of heat cycling; the classic debut is during or just after a self-clean, the hottest duty the fan ever sees.
Heat-damaged connector or harness in the fan circuit
The fan's plug and wiring live in the hot zone behind the control area; a discoloured or loose connector interrupts the circuit the control is monitoring.
The control board's fan output has failed
The least common branch: the board stops powering a proven fan or misreads its circuit. It earns consideration only after the fan, its path and its connector all prove good.
The heat-soaked debut: a fan or connector that fails only when hot
F350's favourite first appearance is during or just after self-clean, or deep into a long, hot bake — the cooling fan's hardest duty. A motor whose bearings stiffen as they heat, or a connector that expands open at temperature, can behave perfectly through a week of ordinary cooking and fault only at the extremes. The debut timing is therefore evidence, and it is perishable: write down which cycle produced the code before the oven cools and the story becomes 'it just showed F350 one day'.
Grease and dust loading on the fan itself
The cooling fan breathes kitchen air for years, and what kitchen air carries — grease vapour and dust — settles on blades and in housings. A fan can be electrically perfect and mechanically strangled: slowed below the speed the control expects, or stalled outright on a build-up an owner would recognise instantly if the fan were visible. This is the material form of GE's 'obstruction', and it is why the fix order on this code is look first, buy later.
The upper fan of two: built-in and double-oven geometry
GE's wording says 'upper' because models with two cavities manage more than one airflow. On double wall ovens an F350 can therefore belong to the upper cavity's fan story while the lower cavity's behaviour stays normal — one more reason to record which cavity was in use. Owners who report 'the oven shows F350 but the lower oven works' have already done the technician's first localisation step.
Checks to run before you replace anything
- Note the debut: during or after self-clean, during a long high bake, or at power-on? Cooling-fan faults overwhelmingly debut around the hottest cycles.
- With the oven cool and the breaker off, check the vent areas and the fan's air path for anything stored, fallen or displaced against them — owners regularly find the obstruction from outside.
- On a short test bake (after resetting the breaker once), listen for the cooling fan: on models that use one it is usually audible during and after cooking, continuing into cool-down. Silence where the fan used to run is the diagnosis pointing at the motor or its circuit.
- If the fan runs but sounds rough, slow or intermittent, treat it as a failing motor rather than a control problem until proven otherwise.
- Listen through a cool-down, not just a cook: on models with a cooling fan it characteristically keeps running after the elements switch off, bringing the electronics bay down to a safe temperature. A fan that used to be audible in cool-down and is now silent has told you its branch; a fan that runs in cool-down but the code stands anyway points at the circuit's reporting side rather than the motor's muscle.
- Check the cheap geography first: vents above and behind the control area clear, nothing stored against them, no pan or tray parked where the installation never intended one, and no foil anywhere it could have migrated from. Owners find the obstruction from outside often enough that GE lists it in the definition — spend the five minutes before anyone prices a motor.
- Distinguish cold-present from hot-earned: an F350 showing at power-on, before any cooking, is a hard fault (obstruction, open motor, open connection). An F350 that only arrives after self-clean or a long bake is the heat pattern. The two patterns send the technician to different first tests, and you are the only witness who can report which one your oven shows.
How to fix f350 error code ge oven?
- Clear any obstruction from the fan and its vents, then reset the breaker for several minutes and test with a moderate bake.
- With the breaker off, inspect the fan connector and harness for heat discolouration or looseness; reseat or replace a damaged plug rather than cleaning it twice.
- Replace the cooling fan motor if it is seized, open, or stalls under power — on built-in wall ovens this is usually technician work because the unit must come out of the cabinet.
- Only if the fan and its circuit prove good end-to-end should the control board be condemned, and on these newest controls that conclusion belongs to a GE-equipped technician with the model's service data.
- Work GE's branches in GE's order: clear the fan's air path completely and retry on a moderate bake before any part is priced. A surprising share of this code is cured by the branch that costs nothing, and a fan motor replaced over a blocked vent leaves the blockage in place to fault the new motor.
- Judge a replacement fan by behaviour, not by the meter alone: under power it should start promptly, run steadily and keep running through cool-down; a fan that starts only when nudged, slows audibly, or dies as it heat-soaks has failed the only test that matters, whatever its winding measured on the bench.
- On a built-in wall oven, price the access into the decision: reaching the upper fan commonly means the unit comes out of the cabinet, which is technician work with lifting equipment. The owner-side contribution is the pattern log — debut cycle, cold-versus-hot behaviour, cavity — because on a code with two branches, the log is what stops a service visit becoming an exploratory excavation.
The part that usually fails: Cooling fan motor
Judge it by behaviour: it should spin freely by hand (power off) and run steadily under power. A fan that is stiff, noisy, or starts only when nudged is done, whatever the meter says about its winding.
Ge oven f350 error code reset
Breaker off for several minutes after the repair, then a moderate bake test: the code clears when the control sees the fan circuit behave, and the fan audibly running through the bake and cool-down is the proof.
GE range F-codes clear with a power reset: trip the breaker for about 5 minutes, restore power, and run a bake test. Codes that return during the start-up self-check (GE boards test the sensor circuit and keypad within seconds of power-up) point at an active component fault, not a stored glitch.
Why does the F350 code keep coming back?
F350 that returns only around self-clean or very long bakes is the heat pattern — a connector expanding open when hot, or a motor that fails as it heat-soaks. F350 present from a cold power-on is a hard fault: obstruction, open motor, or open circuit. Log which pattern yours shows before the technician visit; it halves the diagnosis. F350's return pattern is unusually legible. Returning only around self-clean or very long bakes is the heat file: a connector expanding open, a motor failing as it heat-soaks, or an air path that copes until the fan's hardest duty. Returning from a cold power-on is the hard file: obstruction, open motor, open circuit. Returning within days of an obstruction being cleared suggests the obstruction's source is still feeding the fan — grease load upstream, or something stored that migrates back. Log which file yours belongs to before the service call; on this code the pattern is worth real money, because it decides whether the technician's first hour goes to a vent, a connector or a motor.
How to stop F350 coming back
- An obstruction in the cooling fan: Foil, a displaced piece of insulation, a pan stored against a vent, or debris drawn into the fan housing can stall the fan or slow it below what the control expects — GE lists obstruction first for a reason.
- The cooling fan motor itself has failed: Fan motors seize or open electrically after years of heat cycling; the classic debut is during or just after a self-clean, the hottest duty the fan ever sees.
- Heat-damaged connector or harness in the fan circuit: The fan's plug and wiring live in the hot zone behind the control area; a discoloured or loose connector interrupts the circuit the control is monitoring.
Retrieving stored fault codes on GE oven & ranges
GE electronic range controls store fault codes (the F-code family) that often display only briefly or in a service mode; many GE boards show the last fault when a specific pad combination is pressed (detailed in the service manual for the control). The F-code chart is also printed on the tech sheet stored with the range (often in an envelope near the storage drawer or behind the rear panel).
Other GE oven & range error codes
| Code | Meaning | First fix |
|---|---|---|
| Bad Line | Unit is wired incorrectly; displays when power is applied to the unit but it has not been wired correctly | Do not keep resetting it; contact the installer or a licensed electrician to correct the mis-wire, after which GE says the oven will function normally |
| ERR | Invalid entry when setting the oven controls; not a hardware fault | Press Cancel/Off and re-enter the cooking settings in the correct order |
| F0 | Keypanel problem; GE says the keypanel usually needs to be replaced | Press Cancel/Off, allow the oven to cool for one hour and cut power for at least 30 seconds; if the code repeats, call for service |
| F1 | Keypanel problem; GE says the keypanel usually needs to be replaced | Press Cancel/Off, allow the oven to cool for one hour and cut power for at least 30 seconds; if the code repeats, call for service |
| F2 | Oven temperature too high — the control sensed an over-temperature condition (or a sensor reading that implies one) during bake. | Replace the temperature sensor if its resistance is out of family. |
| F3 | GE's official fault list defines F3 in one sentence: 'This code usually means that the oven sensor needs to be replaced.' F4 carries the identical GE definition; GE's public list does not split F3 and F4 into open vs shorted. | Replace the oven temperature sensor — GE's documented remedy for F3 — ordered by the full model number. |
| F4 | Oven sensor fault; GE says the oven sensor usually needs to be replaced | Press Cancel/Off and allow the oven to cool for one hour; sensor replacement is service work if the code repeats |
| F5 | Electronic control fault; GE says the electronic control usually needs to be replaced | Cut power at the breaker for a minute or two to try to clear it; if it repeats, keep the oven off at the breaker and call for service |
| F6 | Keypanel problem; GE says the keypanel usually needs to be replaced | Press Cancel/Off, allow the oven to cool for one hour and cut power for at least 30 seconds; if the code repeats, call for service |
| F7 | Keypanel problem — GE's published definition: F7 usually means there is a problem with the keypanel, and many times the keypanel needs to be replaced. | Complete the dry-out if moisture is plausible, then retest: a panel that works dry and stays working was never a parts failure — and change the habit that wet it (spray the cloth, not the panel). |
| F7X | Internal component fault; GE says an internal component usually needs to be replaced (F7 followed by another character) | Cut power at the breaker for a minute or two; if the code repeats, call for service with the full model number |
| F8 | Electronic control fault; GE says the electronic control usually needs to be replaced | Cut power at the breaker for a minute or two to try to clear it; if it repeats, keep the oven off at the breaker and call for service |
| F9 | Door lock circuit fault — GE's published definition: a component has failed somewhere in the door lock circuit. | Complete GE's unlock/reset sequence (cool fully, 30 seconds power off, then the short self-clean reset if the door stays locked and empty) — a lock fault caused by a control state or a heat-stuck switch often ends there. |
| F20 | GE's official fault list groups F2 and F20 in a single row: 'For an unknown reason, the oven temperature has exceeded a preset threshold.' GE publishes no preset temperature for this code and names no part for it. | If the oven genuinely overheated — element visibly held on, runaway heat — leave the breaker off and book service. A runaway heating fault is the one member of this code family that is a fire risk, and it is not a reset-and-watch case. |

Codes F350 gets confused with
F96 — Internal component fault — GE's published fault list defines F96 in one sentence: 'This code usually means that an internal component needs to be replaced.' F97 and F7X carry the identical GE definition. GE's public list does not name which component; the model's own service information splits the branch. F96 is GE being deliberately non-specific, and the page has to start there, because the internet is not: technician Q&A pages attach F96 to particular parts — a cooling fan on one model, a control or sensor story on another.
F7 — Keypanel problem — GE's published definition: F7 usually means there is a problem with the keypanel, and many times the keypanel needs to be replaced. F7 is GE's keypanel code, the touch panel you set the oven with.
F3 — GE's official fault list defines F3 in one sentence: 'This code usually means that the oven sensor needs to be replaced.' F4 carries the identical GE definition; GE's public list does not split F3 and F4 into open vs shorted. GE groups its sensor codes by the part, not by the electrical failure mode: F2/F20 = the oven temperature has exceeded a preset threshold; F3 and F4 = the oven sensor usually needs to be replaced.
F20 — GE's official fault list groups F2 and F20 in a single row: 'For an unknown reason, the oven temperature has exceeded a preset threshold.' GE publishes no preset temperature for this code and names no part for it. F20 is a temperature event, not a sensor verdict.
Frequently asked questions
What does F350 mean on a GE oven?
GE's published fault list defines F350 as a problem in the upper cooling fan circuit, or an obstruction in the cooling fan. The control has detected that the cooling fan is not running as expected and typically blocks heating until it is resolved.
Is F350 a temperature sensor fault?
No. F350 sits numerically near the F3 sensor family, which causes the confusion, but GE defines F350 as the cooling fan circuit. The sensor-family codes on these controls are the F3/F34 branch.
Can I still cook with F350 showing?
On most models the oven will not heat while the code stands, because the control will not run the cavity without its cooling fan proven. Do not defeat the lockout — the fan protects the electronics and surrounding cabinetry from heat.
How do I reset the F350 error code on my GE oven?
There is no F350-specific reset ritual. Use GE's general fault-code reset: shut off the circuit breaker or fuse supplying the oven for a minute or two, then restore power. Then test honestly — a moderate bake during which you can hear the cooling fan run, and keep listening through cool-down. If F350 returns, the reset has done its diagnostic job: the fault is in GE's two branches (the fan's air path, or the fan circuit), and resetting again will not clear either.
How do I fix the F350 error code on a GE oven?
Start where GE's definition starts: with obstruction. Clear anything stored against the vents and check the fan's air path, reset at the breaker, and test with a moderate bake. If the fan is silent where it used to run, sounds rough or slow, or the code returns only around self-clean and long bakes (the heat pattern), the fault is in the fan circuit — motor, its connector and harness, then the control's output — and on most models, especially built-in wall ovens, that diagnosis and the motor replacement are technician work.
Does F350 mean the same thing on a GE electric oven and a GE wall oven?
Yes — GE publishes one fault list for its ranges and wall ovens with electronic oven controls, and F350's row is the same for both: an issue with the upper cooling fan circuit, or an obstruction in the cooling fan. What differs is access, not meaning: on a free-standing range the fan area is comparatively reachable, while a wall oven usually has to come out of its cabinet, which is why the same code is a smaller job on a range than on a built-in.
How to fix f350 error code ge oven?
Start here: Clear any obstruction from the fan and its vents, then reset the breaker for several minutes and test with a moderate bake. With the breaker off, inspect the fan connector and harness for heat discolouration or looseness; reseat or replace a damaged plug rather than cleaning it twice.
