OEM Carrier Hot Surface Igniter Kit 331930-751 for Model PG8JAA048070ABJA

This is the genuine OEM Carrier hot surface igniter replacement kit (part #331930-751) factory-specified for the Carrier PG8JAA048070ABJA gas furnace. The hot surface igniter is the first active component in every heating cycle — the control board energizes it to glow at extreme temperature, igniting the gas burners. When the igniter fails, the furnace will attempt a heat cycle, fail to light, and go into lockout — leaving your home cold. You may hear the inducer motor start and gas valve click, but no ignition follows. Replacing the igniter with this OEM kit restores reliable, safe operation immediately.

• Specs: 120V hot surface igniter (HSI) | Silicon nitride element — superior durability and heat resistance vs. older silicon carbide | Includes igniter and mounting bracket | Direct OEM drop-in fit for Carrier PG8JAA048070ABJA
• OEM vs Generic: This factory-authorized kit includes the OEM silicon nitride element and correct mounting hardware, ensuring exact fit and full factory tolerance. Generic igniters may use lower-grade silicon carbide elements that are more brittle and prone to thermal shock cracking, shortening service life significantly.
• Install difficulty: 2/5 — Turn off gas supply and 120V power at the disconnect before beginning. Tools needed: 1/4" nut driver, Phillips screwdriver. Critical: handle the igniter by the ceramic base and wiring harness ONLY — never touch the silicon nitride element with bare hands. Skin oils cause premature failure at operating temperature. Photograph the wiring connector orientation before removal.
• Warranty: 1-year OEM factory warranty. In stock — ships same business day from our warehouse.
