GE Oven F350 Error Code: Oven Control Board Fault Fix

Quick Answer

GE F350 is a self-diagnosed control board fault that appears on GE Profile and select GE freestanding ranges. The board-specific nature of F350 distinguishes it from sensor-related codes: there is no external component to test first because the board is reporting its own internal failure.

In my fifteen years of service calls, I usually see the F350 pop up right after a summer thunderstorm or a sudden power flicker. While the manual technically lists this as a fatal board error, it's often just a logic glitch caused by a voltage spike. Before you spend hundreds on a new control module, you need to do a deep discharge of the capacitors to see if the board can clear its own memory.

What Does the F350 Code Mean?

The F350 is basically the brain of your GE oven telling you it's got an internal problem it can't sort out on its own. Unlike codes that point to a bad sensor or a burnt element, this fault is strictly about the electronics inside the control board. It's pretty common on the GE Profile series where complex circuitry gets cooked by high kitchen heat over the years. Good news is it's not always a dead board.

Most Likely Causes

Based on aggregated repair data, here is the probability breakdown for this error code:

Control board internal component failure40%

Power surge or fluctuation corrupting board firmware state24%

Overheating damage from failed cooling fan (secondary cause)22%

Age-related failure of board capacitors or relay drivers14%

Symptoms You May Notice

F350 is flashing on the control panel and won't clear no matter what buttons you press
The whole oven feels completely dead, like the touch panel isn't responding at all even though the clock might still show a time
You can hear a relay click when you power it on, but zero heat comes from the bake or broil elements
The code comes right back within a minute or two even after you flip the breaker off and on
On SmartHQ-connected models, the app shows the oven as offline or throws a connectivity error at the same time the code appears

Can you reset a Ge oven to clear the F350 code?

Flip the circuit breaker for the oven to the OFF position and leave it there for at least sixty seconds. That wait time actually matters because it lets the stored electricity in the board's capacitors fully drain. If your range is a newer SmartHQ model, also try a factory reset through the app settings after the breaker reset. If the code comes back after both of those, the hardware's failed and a reset won't fix it.

Replacement Parts

If your diagnostic testing proves the component has failed, you will need a replacement. We recommend OEM parts over aftermarket for water-handling components.

Frequently Asked Questions

Is GE F350 always a board failure?

Honestly, it's about a 50/50 split. If you just had a power outage or a brownout, there's a good chance the board is just confused and a hard reset will save you. But if the code appeared right in the middle of a high-heat cooking cycle or a self-clean, the heat probably fried a relay or a capacitor. In those cases the board is physically damaged and no amount of resetting will bring it back.

How is GE F350 different from Fault 353?

Think of F350 as the board failing its own internal health check. It knows something's wrong inside its own circuits. Fault 353 is more like a bad phone connection between the oven board and the cooktop board. While they both involve the electronics, F350 is way more likely to require a total board replacement because the problem's deep inside the main processor or the power supply section of the clock.

What does a GE oven control board replacement cost to have done professionally?

You're usually looking at a bill between $300 and $500. GE control boards are expensive on their own, often running $200 or more just for the part. Add in the service call and labor to pull the range out and swap the wiring harnesses, and it adds up quick. If your range is less than 8 or 9 years old, I'd usually say fix it. If it's a basic model pushing 15 years, you might be better off putting that money toward a new unit.

Can I replace the GE oven control board myself?

Yeah, honestly it's one of the more DIY-friendly repairs on a GE range if you're comfortable working around appliances. The hardest part is usually pulling the range out and getting the back panel off. Once you're in there, it's mostly just disconnecting a bunch of keyed wiring harness connectors and swapping the board. The connectors are all shaped differently so you basically can't plug them in wrong. I'd call it a solid intermediate repair, maybe 45 minutes start to finish if you've done anything like it before. Just don't skip the breaker step.

How do I find the right replacement board for my specific GE model?

Pull the model number off the sticker inside the oven door frame, not off the back of the range. That's the one you need. Then check the part number printed on the old board itself, usually something starting with WB27. Search both on Repair Clinic or AppliancePartsPros. A lot of GE boards look identical but have different part numbers, and GE doesn't always cross them over cleanly. Getting the wrong board is a real headache, so double-check both numbers before you order anything.
