OEM Carrier Hot Surface Igniter Kit 331930-751 for Model PG8MAA036045AAJA

This is the factory-authorized OEM hot surface igniter replacement kit for the Carrier PG8MAA036045AAJA gas furnace. The hot surface igniter is the component your furnace's control board energizes at the start of every heat call — it glows to ignition temperature within seconds and directly lights the gas burner. When the igniter fails, the furnace enters a hard lockout after one or more failed ignition attempts, leaving you with no heat. Common symptoms include the inducer running normally but no ignition, a blinking fault code for ignition failure, or a visibly cracked igniter element.

• Specs: 120V Hot Surface Ignition (HSI) | Silicon nitride flat igniter element | Includes OEM mounting bracket, wire harness, and high-temperature wire nuts | Upgrades and replaces original part number LH33ZS004 on 33" tall mid-efficiency furnace cabinets
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part (part number 331930-751), engineered to exact factory tolerances for the PG8MAA series. Generic igniters may vary in element geometry and resistance ratings, risking premature failure or mis-timed ignition sequences that can damage the gas valve.
• Install difficulty: 2/5 — Turn off gas supply and 120V power before starting. Tools needed: 1/4" nut driver, needle-nose pliers, and work gloves (never touch the silicon nitride element with bare hands — skin oils cause hot spots and early failure). Photograph all wiring connections before removal. The included bracket and harness make this a straightforward drop-in upgrade.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
