OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG8MAA024045AGJA

This is the factory OEM hot surface igniter (part number LH33ZG001) for the Carrier PG8MAA024045AGJA packaged gas unit. The igniter is the critical first step in the heating sequence — during a call for heat, the control board energizes the igniter, which glows to ignition temperature and lights the gas burner. When the igniter fails, the furnace will attempt ignition, fail to establish flame, and go into lockout — leaving you with no heat. Common symptoms include the system cycling on and off repeatedly, a no-heat fault code, or a visibly cracked or broken igniter element.

• Specs: 120V hot surface igniter | Silicon nitride element | Includes mounting bracket and wiring harness | Factory-matched fit for Carrier PG8MAA024045AGJA
• OEM vs Generic: This genuine Carrier OEM igniter is manufactured to exact factory resistance and temperature specifications. Generic igniters can vary in element composition and geometry, leading to unreliable light-off and premature failure — especially in packaged units with tight tolerances.
• Install difficulty: 2/5 — Always de-energize and disconnect power before servicing. Tools needed: 1/4" nut driver, flat-head screwdriver, needle-nose pliers. Never touch the igniter element with bare hands — skin oils cause hot spots and early element failure. Photograph wiring connections before disconnecting the harness.
• Warranty: 1-year OEM factory warranty. In-stock orders ship same business day from our warehouse.
