OEM Carrier Hot Surface Igniter Kit 332505-751 for Model GB3AAV036075ABJA

This is the factory-specified OEM hot surface igniter replacement kit (part number 332505-751) for the Carrier GB3AAV036075ABJA gas furnace. The hot surface igniter is a critical component in the ignition sequence — it heats to approximately 2,500°F to ignite the gas burners on each heating cycle. When the igniter fails, the control board will detect no flame establishment and lock out the furnace, leaving you with no heat. Common symptoms include a furnace that attempts to start, runs the inducer, but never produces a flame and flashes a fault code.

• Specs: Silicon nitride hot surface igniter | OEM part number 332505-751 | Includes mounting hardware and wiring harness connector | Factory-matched resistance and watt density for GB3AAV036075ABJA
• OEM vs Generic: This OEM kit is manufactured to Carrier's exact fragility, resistance, and heat-up timing specifications. Generic igniters frequently use silicon carbide elements with inconsistent resistance values, causing nuisance lockouts or premature cracking — especially in cold-start conditions.
• Install difficulty: 2/5 — Turn off gas supply and 120V power before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Never touch the igniter element with bare hands — skin oils cause hot spots and early failure. Replacement typically takes 20–30 minutes.
• Warranty: 1-year OEM factory warranty against defects. Orders received before cutoff ship same business day from our climate-controlled warehouse.
