OEM Carrier Hot Surface Igniter Replacement Kit 332505-751 for Model GB3AAV036050ACJA

This is the factory OEM hot surface igniter replacement kit (part number 332505-751) designed specifically for the Carrier GB3AAV036050ACJA gas furnace. The hot surface igniter is a critical component in the ignition sequence — it heats to over 1,800°F to ignite the gas burners on each heating cycle. When it fails, the furnace will attempt ignition, fail to establish a flame, and lock out — leaving you with no heat. Common symptoms include a furnace that clicks through its startup sequence but never fires, or a visible crack in the igniter element upon inspection.

• Specs: Silicon nitride hot surface igniter | Factory-matched voltage and wattage rating | Includes mounting hardware and wiring harness per OEM kit specification | Direct drop-in replacement — no modifications required
• OEM vs Generic: This OEM kit (332505-751) is manufactured to Carrier's exact electrical resistance and thermal specifications. Generic igniters often deviate in wattage and element geometry, leading to premature cracking, inconsistent ignition timing, and shortened service life — especially through cold-weather high-cycle seasons.
• Install difficulty: 2/5 — Always disconnect power and shut off gas before servicing. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Handle the igniter element only by its ceramic base — skin oils cause hot spots and early failure. Photograph wiring connections before disconnecting.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.
