OEM Carrier Hot Surface Igniter Kit 331930-751 for Model PG8MAA060155AAJA

This is the genuine OEM Carrier hot surface igniter replacement kit (part #331930-751) factory-specified for the Carrier PG8MAA060155AAJA gas furnace. The hot surface igniter is the component that heats to over 1800°F to ignite the gas burner on every call for heat. When it cracks, burns out, or degrades, the furnace will attempt ignition, fail to light, and lock out — leaving you with no heat. Replacing it with the correct OEM kit restores reliable, factory-matched ignition performance.

• Specs: 120V hot surface igniter (HSI) | Silicon nitride element — superior durability vs. older silicon carbide | Complete kit includes igniter element, mounting bracket, wire harness, and high-temperature wire connectors | Replaces legacy part numbers LH33ZS004, LH33ZS003, LH33ZS002, LH33ZS001 on 33" tall mid-efficiency furnace platforms
• OEM vs Generic: This is the genuine Carrier factory kit — not a universal substitute. OEM silicon nitride igniters are manufactured to exact resistance tolerances (cold resistance: 34–64 Ohms @ 75°F) and reach ignition temperature in under 17 seconds. Generic units may fall outside tolerance, causing nuisance lockouts or premature failure.
• Install difficulty: 2/5 — A straightforward swap for a competent DIYer or technician. Tools needed: 1/4" nut driver, flathead screwdriver, needle-nose pliers. Always shut off gas and power to the furnace before beginning. Photograph existing wiring before disconnecting. The included bracket and harness make this a clean, plug-and-play upgrade from older carbide igniters.
• Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our warehouse.
