OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG92SBS66100CBAA

This OEM hot surface igniter (part number LH33ZG001) is the factory-specified replacement for the Carrier PG92SBS66100CBAA 92% AFUE single-stage gas furnace. The igniter heats to over 2,000°F to ignite the gas burners during each heating cycle. When it fails, the furnace control board detects no flame establishment and triggers a lockout after one or more failed ignition attempts — leaving you with no heat and often a fault code on the board.

• Specs: Hot surface igniter | Silicon nitride element | Factory OEM replacement for Carrier LH33ZG001 | Engineered to exact resistance and wattage tolerances for the PG92SBS66100CBAA burner assembly
• OEM vs Generic: OEM igniters use factory-matched silicon nitride rated for precise heat-up timing. Off-brand igniters often vary in resistance and physical geometry, causing delayed ignition, nuisance lockouts, or premature cracking at the element.
• Install difficulty: 2/5 — Turn off gas supply and 120V power before servicing. Tools needed: 1/4" nut driver, needle-nose pliers. Handle the igniter element only by its ceramic bracket — never touch the silicon nitride tip with bare hands, as skin oils cause hot spots and early failure.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
