GE Cooktop Error Code FA8

FA8 indicates a bad or failed induction driver, specifically the IGBT (Insulated Gate Bipolar Transistor), which is the high-power switching component that drives the induction coil in one or more cooking zones. The cooktop displays this code when it detects the IGBT or its associated driver circuit is not functioning correctly. The affected cooking zone will be disabled until the fault is resolved. Repair requires replacement of the induction tray assembly.

No, you should not attempt to use the cooktop while FA8 is active. The error indicates a hardware failure in the induction driver circuit, and continued use could cause additional damage to the control board or other internal components. The cooktop will typically disable the affected zone automatically, but the safest course is to stop using the appliance until it has been repaired.

Repair costs vary depending on the specific cooktop model and the price of the induction tray assembly required. Parts alone can range from roughly $150 to $400 or more for the induction tray, with professional labor adding $100 to $200 on top of that in most markets. Getting a parts quote for your specific model number before committing to repair is a good way to determine whether the repair is cost-effective compared to replacement.

Addressing FA8 requires replacing the induction tray assembly, which involves working with high-voltage components inside the cooktop. Technicians with appliance repair experience and proper safety precautions can perform this repair, but it is not recommended for general DIY work due to the risk of electric shock from capacitors that can retain charge after power is removed. Always disconnect power and allow adequate discharge time before opening the unit.

A power reset, such as turning off the circuit breaker for 30 seconds and restoring power, may temporarily clear the FA8 code if the fault was caused by a transient condition. However, if the IGBT or induction driver board has physically failed, the code will return as soon as the cooktop attempts to operate that zone again. A reset alone is not a repair for this fault.
