This OEM hot surface igniter kit (part number 332505-751) is the factory-specified ignition replacement for the Carrier GB1AAV036065AGJA gas furnace. The hot surface igniter is the first component in the ignition sequence — the control board energizes it to reach temperatures exceeding 1,800°F, igniting the gas burners. When the igniter fails or cracks, the furnace will attempt ignition, fail to light, and go into safety lockout, leaving you with no heat. Common symptoms include a furnace that clicks or cycles without producing heat, error codes indicating ignition failure, or a visibly cracked or broken igniter element.
Compatibility: Designed specifically for the Carrier GB1AAV036065AGJA gas furnace. Verify your existing igniter's part number against 332505-751 before ordering, and confirm your furnace model on the rating plate inside the blower compartment door. Need help confirming fitment?
