OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG95SAS30040ABAA

This is the factory OEM hot surface igniter (part# LH33ZG001) for the Carrier PG95SAS30040ABAA 95% AFUE packaged gas furnace. The igniter is the first component activated during every heating cycle — the control board energizes it to reach surface temperatures exceeding 1,800°F, which then directly ignites the gas burner. When this part fails, the furnace will attempt ignition, fail to light the burner, and lock out — leaving you with no heat and a fault code on the control board. Cracked elements, surface contamination from oils, and normal thermal cycling are the most common causes of igniter failure.

• Specs: 120V hot surface igniter | Silicon nitride element | Includes mounting bracket and wiring harness | Factory-matched geometry for drop-in replacement
• OEM vs Generic: This OEM igniter is manufactured to Carrier's exact resistance and thermal shock specifications. Generic igniters often use silicon carbide elements with wider tolerance ranges, leading to premature cracking and repeat failures — especially in high-cycle applications.
• Install Difficulty: 2/5 — Always de-energize the unit and allow the igniter to cool fully before handling. Never touch the igniter element with bare hands — skin oils cause hot spots and premature failure. Tools needed: 1/4" nut driver, needle-nose pliers. Disconnect wiring harness, remove mounting screw, swap igniter, reconnect harness. Verify ignition sequence on first call for heat.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.
