OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG9MAB036060ACSA

This is the factory OEM hot surface igniter for the Carrier PG9MAB036060ACSA packaged gas unit. On a call for heat, the control board energizes this igniter to glow at extreme temperature, igniting the gas burner. When the igniter fails — due to cracking, contamination, or element degradation — the furnace will attempt ignition, fail to prove flame, and enter a hard lockout, leaving you with no heat. Replacing this igniter with the correct OEM part restores reliable ignition and prevents nuisance lockouts.

• Specs: OEM Part # LH33ZG001 | 120V AC | Silicon nitride element | Factory-matched element resistance and warm-up timing for Carrier control board compatibility
• OEM vs Generic: OEM igniters are manufactured to exact Carrier tolerances for resistance, glow temperature, and warm-up time. Generic igniters can vary in resistance, causing premature lockout or shortened element life — especially in tightly timed Carrier control sequences.
• Install Difficulty: 2/5 — De-energize and disconnect power before servicing. Tools needed: 1/4" nut driver, needle-nose pliers. Critical: never touch the silicon nitride element with bare hands — skin oils cause hot spots that crack the element. Use gloves or handle by the bracket only.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
