OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG8MEA048070AAJA

This is the genuine OEM hot surface igniter for the Carrier PG8MEA048070AAJA packaged gas unit. On every call for heat, the control board energizes this igniter to reach glowing temperatures — typically 1,800–2,200°F — before opening the gas valve to light the burner. When the igniter fails, the furnace will attempt ignition, fail to establish flame, and lock out after one to three tries. You may hear the inducer run and the system attempt to cycle, but no heat is produced.

• Specs: OEM Part # LH33ZG001 | 120V AC input | Silicon nitride element | Factory-matched geometry and wiring harness connector for drop-in fit
• OEM vs Generic: This is the genuine Carrier factory part, ensuring correct element resistance, watt density, and connector fit. Generic igniters often use silicon carbide, which is more fragile and prone to cracking during thermal cycling — shortening service life significantly.
• Install Difficulty: 2/5 — Always de-energize the unit at the disconnect before servicing. Never touch the ceramic igniter element with bare hands — skin oils create hot spots that cause premature failure. Tools needed: 1/4" nut driver, flathead screwdriver, needle-nose pliers. Photograph the wiring harness routing before removal.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before cutoff.
