OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG8JEB036045AAJA

This OEM hot surface igniter (part number LH33ZG001) is the factory-specified replacement for the Carrier PG8JEB036045AAJA gas furnace. The igniter is a critical ignition component that glows to extreme temperatures to light the gas burner during each heating cycle. When it fails, the furnace control board will detect no ignition, lock out the system after 1–3 attempts, and leave you with no heat. Common symptoms include the inducer running normally but the burners never lighting, along with a blinking fault code on the control board indicating an ignition failure.

• Specs: OEM Part No. LH33ZG001 | Hot surface igniter type | Silicon nitride element | Factory-matched electrical resistance and mounting configuration for direct drop-in replacement
• OEM vs Generic: This is the genuine OEM Carrier igniter, manufactured to exact factory specifications. Generic igniters frequently deviate in resistance, physical geometry, and mounting bracket alignment — leading to premature cracking, misfire, or improper flame position. OEM is always the recommended choice for longevity and reliability.
• Install Difficulty: 3/5 — Always shut off gas supply and 120V power before servicing. Never touch the ceramic igniter element with bare hands — skin oils cause hot spots and premature cracking. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (to verify ~40–90Ω resistance). Photograph wiring harness before disconnecting.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.
