GE Range Error Code FA10

The FA10 error code on a GE induction range indicates a bridge board fault within the induction cooktop system. The bridge board, sometimes called the inverter bridge board, is the high-voltage power conversion component responsible for transforming AC line power into the high-frequency AC that drives the induction coils beneath the cooktop surface. When the control system detects an abnormal condition in this board, such as a switching failure, overcurrent event, or internal component failure, it triggers the FA10 code and disables the induction burners to prevent further damage or a safety hazard.

The bridge board contains power transistors or IGBTs (insulated gate bipolar transistors) that switch at high frequency to energize the coils. These components are subjected to significant thermal and electrical stress during normal operation. Failures can stem from a single shorted or open transistor, a failed gate driver circuit, damaged capacitors on the board, or a failure in the thermal management of the board itself. In some cases, a hard fault in the board will appear immediately at startup, while intermittent failures may only appear under load when the burners are actively heating.

Because the FA10 code points directly to the bridge board as the faulty component, the primary diagnostic step is replacement of that board. Before replacing, technicians should verify that line voltage is correct at the unit and that there are no obvious signs of burning, arcing, or physical damage to the wiring harness and connectors leading to the board. A failed board often shows visible signs of component burnout or swollen capacitors on close inspection.
