OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG92SBS66120DBAA

This OEM hot surface igniter (part number LH33ZG001) is the factory-specified replacement for the Carrier PG92SBS66120DBAA 92% AFUE gas furnace. The igniter is a silicon nitride element that heats to approximately 2,500°F to ignite the gas burner on every call for heat. When it fails — through cracking, burnout, or age-related resistance drift — the furnace control board will attempt ignition, detect no flame, and lock out the unit. The result is a no-heat call with a fault code indicating ignition failure.

• Specs: Silicon nitride hot surface igniter | 120V input | OEM factory-matched resistance rating | Direct plug-in connector — no splicing required
• OEM vs Generic: The OEM LH33ZG001 is manufactured to exact Carrier resistance and geometry specifications. Generic igniters can vary in element thickness, resistance tolerance, and bracket alignment — increasing the risk of nuisance lockouts or premature failure.
• Install Difficulty: 2/5 — Turn off power and gas before servicing. Tools needed: 1/4" nut driver, needle-nose pliers. Never touch the ceramic element with bare hands — skin oils cause hot spots that crack the element. Use gloves or a clean cloth throughout installation.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
