OEM Carrier Hot Surface Igniter Replacement Kit 332505-751 for Model PG8UAA042091ABJA

This OEM hot surface igniter kit (part number 332505-751) is the factory-specified replacement for the Carrier PG8UAA042091ABJA gas furnace. The hot surface igniter is the first component activated in every heating cycle — it heats to over 2,000°F to ignite the gas delivered by the combination valve. When it fails, the furnace control board will attempt ignition one or more times and then lock out, leaving you with a no-heat condition. Common symptoms include a blinking error code on the control board, the burners never lighting, or a visible crack in the igniter element.

• Specs: OEM Carrier igniter replacement kit | Part No. 332505-751 | Silicon nitride element (preferred over silicon carbide for longevity) | Factory-matched voltage and wattage for the PG8UAA042091ABJA furnace platform
• OEM vs Generic: This OEM kit includes factory-matched mounting hardware and a connector that mates directly to the furnace wiring harness — no splicing required. Generic igniters often require adapter harnesses and may run at incorrect wattage, shortening element life or causing nuisance lockouts.
• Install difficulty: 2/5 — Always disconnect power and shut off the gas supply before servicing. 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 that crack the element prematurely. Use gloves or handle by the mounting bracket only.
• Warranty: 1-year OEM factory warranty on parts. Orders placed before cutoff ship same business day from our NationalHVACParts.com warehouse.
