OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG8JAA036110AEJA

This is the genuine OEM hot surface igniter (part number LH33ZG001), factory-specified for the Carrier PG8JAA036110AEJA packaged gas unit. During every call for heat, the control board energizes the igniter, which heats to over 1,800°F to ignite the gas burner. When this component fails — typically due to hairline cracks in the element or degradation from repeated thermal cycling — the furnace will attempt ignition, fail to light, and enter a safety lockout. The most common symptom is a system that clicks through its ignition sequence but delivers no heat, often triggering a fault code on the control board.

• OEM Part Number: LH33ZG001 | Genuine Carrier factory part | Includes bracket and wiring harness for direct plug-in replacement
• OEM vs Generic: This OEM igniter is manufactured to exact Carrier specifications for element resistance, temperature ramp, and mechanical fit. Aftermarket igniters may vary in resistance tolerance, leading to premature cracking or inconsistent ignition — always choose OEM for a safety-critical ignition component.
• Install Difficulty: 3/5 — De-energize and lock out the unit before beginning. Allow the old igniter to cool completely before handling. Never touch the ceramic element with bare hands — skin oils cause hot spots that crack the element. Tools needed: 1/4" nut driver, needle-nose pliers, phone/camera to photograph wiring. Disconnect the harness plug, remove the single mounting screw, swap the igniter, and verify ignition sequence on first call for heat.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before the daily cutoff.
