OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG8JAA066135ACJA

This is the factory OEM hot surface igniter for the Carrier PG8JAA066135ACJA gas furnace. The igniter is the first active component in every heat cycle — it glows to ignition temperature (typically 2,500°F+) to light the burner assembly. When it fails, the furnace will attempt ignition, fail to establish flame, and go into lockout — leaving you with a blinking fault code and no heat. A cracked, broken, or open-circuit igniter is one of the most common causes of furnace no-heat calls.

• Specs: OEM Part Number LH33ZG001 | Silicon nitride hot surface igniter | Factory-matched resistance and geometry for exact fit on Carrier PG8JAA066135ACJA | 120V operating voltage
• OEM vs Generic: This OEM igniter is manufactured to Carrier's exact specifications — including element thickness, resistance tolerance, and mounting bracket geometry. Generic igniters often use silicon carbide elements that are more brittle, run hotter, and have shorter service lives than the OEM silicon nitride design.
• Install difficulty: 2/5 — Turn off gas and 120V power at the disconnect before starting. Tools needed: 1/4" nut driver, flat-head screwdriver. Never touch the igniter element with bare hands — skin oils create hot spots that crack the element prematurely. Use gloves or handle only by the ceramic body and bracket.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before 3PM local time.
