OEM Carrier Hot Surface Igniter Replacement Kit 332505-751 for Model GB3AAV048095ACJA

This is the factory OEM hot surface igniter replacement kit (part number 332505-751) for the Carrier GB3AAV048095ACJA gas furnace. The hot surface igniter is the component responsible for generating the heat needed to light the burner assembly during each heating cycle. When the igniter fails, the control board will typically attempt ignition two to three times before triggering a lockout fault — leaving you with a furnace that runs the inducer and clicks through the startup sequence but never produces heat. A cracked or open-circuit igniter is one of the most common no-heat service calls on this furnace series.

• Specs: Silicon nitride hot surface igniter | Factory-matched electrical resistance | Includes mounting hardware and wiring harness connector as a complete kit | Rated for natural gas and propane applications
• OEM vs Generic: This OEM kit uses factory-spec silicon nitride construction, which offers superior thermal shock resistance and a longer service life compared to aftermarket silicon carbide igniters. Generic igniters may have mismatched resistance values that cause premature burnout or inconsistent ignition timing.
• Install difficulty: 2/5 — Always disconnect power and shut off the gas supply before servicing. Tools needed: 1/4" nut driver, flat-head screwdriver, needle-nose pliers. Handle the igniter element carefully — skin oils can cause premature failure; use gloves or avoid touching the ceramic tip directly.
• Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our warehouse.
