OEM Carrier Hot Surface Igniter Replacement Kit 332505-751 for Model PG8UAA048135ADJA

This OEM hot surface igniter replacement kit (part# 332505-751) is the factory-specified ignition component for the Carrier PG8UAA048135ADJA gas furnace. The hot surface igniter is the first active component in every heating cycle — the control board energizes it to glow white-hot, igniting the gas burners within seconds. When it fails, the furnace will attempt ignition, fail to light, and go into safety lockout — leaving you with no heat. Common symptoms include repeated short cycling, a blinking fault code on the control board, or a furnace that runs the inducer motor but never produces heat.

• Specs: Hot surface igniter replacement kit | Silicon nitride element (preferred over silicon carbide for durability) | Factory-matched electrical resistance | Includes mounting hardware and wire harness connector for drop-in installation
• OEM vs Generic: This OEM kit is manufactured to Carrier's exact resistance and geometry specifications. Generic igniters often ship with mismatched resistance ratings or ill-fitting brackets, causing premature cracking or mis-alignment in the burner assembly — OEM eliminates the guesswork.
• Install difficulty: 2/5 — Turn off gas supply and 120V power at the disconnect before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Handle the igniter element with care — skin oils cause hot spots that crack ceramic elements. The full swap typically takes under 30 minutes.
• Warranty: 1-year OEM factory warranty against defects. In-stock units ship same business day from our warehouse when ordered before 3 PM local time.
