GE Cooktop Error Code FAB

The FAB code on a GE induction cooktop indicates a bad induction driver, specifically a fault with the IGBT (Insulated Gate Bipolar Transistor) inside the induction tray assembly. The IGBT is responsible for switching the high-frequency current that powers the induction coil in a cooking zone. When this component fails, the cooktop disables the affected zone and displays the FAB code. Replacement of the induction tray is the recommended fix.

No, you should not attempt to use the affected cooking zone while the FAB code is active. The cooktop has disabled that zone specifically because it detected a component failure that could pose a risk of further damage or a hazard. Other zones may still function, but the faulty zone should remain unused until the induction tray is replaced.

Repair costs vary depending on the specific cooktop model and local labor rates. The induction tray part itself typically ranges from around $150 to $400 or more depending on the model. Adding professional labor, total repair costs generally fall somewhere between $250 and $600. Getting a parts quote for your specific model number before committing to the repair is recommended, as the part cost on higher-end models can make repair versus replacement worth comparing.

Replacing the induction tray involves working inside an appliance that carries high voltage, so this repair is best handled by a qualified technician. A knowledgeable DIYer who is comfortable with appliance repair can perform the replacement, but the power must be completely disconnected at the circuit breaker before any work begins. The induction tray is a complete modular assembly, so no component-level soldering is required, just disconnecting the wiring harness and mounting hardware.

A power reset by turning off the circuit breaker for a few minutes may temporarily clear the FAB code, but it will return as soon as the cooktop tests the induction driver circuit again. Because the code points to a hardware failure of the IGBT, no amount of resetting will resolve the underlying problem. The induction tray must be replaced to permanently clear the fault.
