OEM Carrier Hot Surface Igniter Kit 332505-751 for Model PG8UAA048111ABJA

This OEM hot surface igniter kit (part number 332505-751) is the factory-specified replacement for the Carrier PG8UAA048111ABJA gas furnace. The hot surface igniter is the critical first step in every heating cycle — it reaches extreme temperatures within seconds to ignite the gas flowing from the burner assembly. When this component fails, the furnace will attempt ignition, fail to light, and enter a safety lockout, leaving you with no heat. Common symptoms include the furnace cycling on the inducer motor but never lighting, a blinking fault code for "failed ignition," or a visibly cracked or broken igniter element.

• Specs: Silicon nitride hot surface igniter | Factory OEM replacement kit | 120V input | Engineered for Carrier PG8UAA series packaged gas furnaces | Rated for high-cycle durability
• OEM vs Generic: This OEM kit is manufactured to Carrier's exact electrical resistance and thermal cycling specifications. Generic igniters frequently use inferior silicon carbide elements that are more brittle, more prone to cracking from vibration, and more susceptible to premature failure from grease contamination or voltage spikes.
• Install difficulty: 2/5 — Shut off gas supply and 120V power at the disconnect before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, work gloves. Critical: Never touch the igniter element with bare hands — skin oils cause hot spots that crack the element. Handle by the ceramic base or wiring harness only.
• Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Orders placed by 3 PM local time ship same business day from our climate-controlled warehouse.

Compatibility: Directly fits the Carrier PG8UAA048111ABJA packaged gas furnace. Always verify your existing part number printed on the igniter body or your unit's wiring diagram before ordering. If you need fitment confirmation, our HVAC parts specialists are available to verify compatibility before you buy — no guesswork, no costly return shipping.
