OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG8MAA024045AEJA

This is the factory OEM hot surface igniter (part number LH33ZG001) for the Carrier PG8MAA024045AEJA packaged gas unit. During a call for heat, the control board energizes the igniter, which glows to ignition temperature and lights the gas burner. When this component fails — due to cracking, contamination, or element burnout — the furnace will attempt ignition, fail to light, and enter a lockout fault after 2–3 retries, resulting in no heat. Replacing the igniter is one of the most common and cost-effective furnace repairs available.

• Specs: 120V hot surface igniter | Includes mounting bracket and wiring harness | Factory-matched element geometry and resistance tolerance for Carrier PG8MAA series packaged units
• OEM vs Generic: This is a genuine OEM Carrier igniter — not an aftermarket substitute. OEM igniters are manufactured to exact dimensional and electrical specs, ensuring proper glow temperature and fit without modification. Generic igniters often vary in resistance and element shape, risking misfires or premature failure.
• Install difficulty: 2/5 — Shut off gas supply and power before beginning. Tools needed: 1/4" nut driver, needle-nose pliers. Avoid touching the igniter element with bare hands — skin oils cause hot spots that crack the element. Photograph the wiring harness routing before disconnecting.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.
