OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG8JAA024045ACJA

This is the factory OEM hot surface igniter for the Carrier PG8JAA024045ACJA gas furnace. The igniter is the first active component in the ignition sequence — the control board energizes it to reach temperatures exceeding 1,800°F, which then ignites the gas flowing from the burner assembly. When the igniter fails, the furnace will attempt to light, fail to sense a flame, and enter a safety lockout — leaving you with no heat. Common symptoms include the inducer running normally but the burner never lighting, or an error code indicating an ignition failure.

• Specs: OEM Part Number LH33ZG001 | Silicon nitride hot surface igniter | Factory-matched geometry and mounting bracket | Rated for 120V ignition circuit
• OEM vs Generic: This is the genuine Carrier OEM igniter, engineered to the exact resistance, watt density, and fragility tolerance of the original. Aftermarket igniters often deviate in wattage or tip geometry, causing slow light-off, cracked tips, or premature failure within one heating season.
• Install Difficulty: 3/5 — Always disconnect power and allow the old igniter to fully cool before handling. Never touch the ceramic tip with bare hands — skin oils cause hot spots that crack the element. Tools needed: 1/4" nut driver, flat-blade screwdriver, needle-nose pliers. Snap a photo of wiring before disconnecting the harness plug.
• Warranty: 1-year OEM factory warranty against defects. In stock and ships same business day from our warehouse.
