GE Cooktop Error Code FA4

FA4 indicates that Fan2, one of the internal cooling fans inside the GE induction cooktop, is not running at the correct high speed. The cooktop monitors fan performance to ensure the induction tray and its electronics are properly cooled. This code appears when the control system detects that Fan2 is underperforming, which can lead to overheating if not addressed.

It is not recommended to continue using the cooktop with an active FA4 error. Fan2 is part of the cooling system that protects the induction tray and its power electronics from overheating. Running the cooktop without adequate cooling could cause further damage to internal components or create a safety hazard.

Repair costs depend on which component has failed. Replacing Fan2 alone is generally the least expensive option, with fan parts typically ranging from around $30 to $80 depending on the model. If the User Interface board or induction tray requires replacement, costs can rise to the $150 to $400 range for parts, plus any labor charges if a technician performs the repair.

A knowledgeable DIYer can start by inspecting the wiring connections between the User Interface board and the induction tray, as loose or damaged wires are a common cause. If the wiring looks intact, testing or replacing Fan2 is the next step. However, if the UI board or induction tray itself is faulty, those repairs typically require more advanced technical skills and may be better handled by a qualified technician.

A reset may temporarily clear the FA4 code, but if the underlying issue with Fan2, the wiring, or the related boards is not repaired, the error will return once the cooktop attempts to run the fan at high speed again. A reset alone is not a fix and should only be used as part of diagnosing whether the fault is intermittent.
