OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG8JAA048135AGJA

This is the factory OEM hot surface igniter (part number LH33ZG001) for the Carrier PG8JAA048135AGJA packaged gas unit. During every heating cycle, the control board energizes this igniter to glow at temperatures exceeding 1,800°F, igniting the gas burner. When it fails — typically due to age, thermal fatigue, or physical cracking — the furnace will attempt ignition, fail to detect a flame, and lock out after one to three tries. You'll have no heat, often with a fault code indicating "ignition failure" or "lockout" on the control board.

• Specs: 120V AC operation | Silicon nitride element | OEM part number LH33ZG001 | Factory-matched resistance and warm-up timing for Carrier packaged gas equipment
• OEM vs Generic: This is the genuine Carrier OEM igniter — factory-matched to the exact voltage ramp profile and element geometry specified for the PG8JAA048135AGJA. Generic aftermarket igniters can have mismatched resistance tolerances, leading to premature burnout or unreliable ignition in cold-start conditions.
• Install difficulty: 2/5 — De-energize the unit at the disconnect before beginning. Do not touch the igniter element with bare hands — skin oils cause hot spots that crack the element. Tools needed: 1/4" nut driver, needle-nose pliers. Unplug the harness connector, remove the single mounting screw, swap the igniter, and verify ignition sequence on first call for heat.
• Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse.
