OEM Carrier Hot Surface Igniter (LH33ZG001) for Model PG8MAA024045AFJA

This OEM hot surface igniter (part number LH33ZG001) is the factory-specified replacement for the Carrier PG8MAA024045AFJA packaged gas unit. During every heating cycle, the control board energizes this igniter to glow red-hot, igniting the gas burner the moment the gas valve opens. When the igniter fails — whether from age, thermal shock, or hairline cracks — the furnace will attempt ignition, fail to establish a flame, and enter a hard lockout, leaving you with no heat. Replacing it with the correct OEM part restores reliable ignition from the very first cycle.

• Part Number & Type: OEM Carrier LH33ZG001 | Silicon Nitride hot surface igniter (Kyocera HSI) — the preferred modern igniter material for longer service life and lower watt draw versus older silicon carbide designs.
• OEM vs Generic: This is the genuine OEM Carrier igniter, manufactured to exact factory geometry, resistance, and mounting specifications for the PG8MAA024045AFJA. Generic igniters may differ in element length or bracket angle, causing misalignment with the burner and nuisance lockouts.
• Install Difficulty: 2/5 — De-energize the unit and allow the igniter to cool completely before removal. Never touch the nitride element with bare hands — skin oils cause hot spots and premature failure. Tools needed: 1/4" nut driver, needle-nose pliers. Disconnect the wire harness plug, remove the single mounting screw, and reverse to install. Verify ignition on first call for heat.
• Warranty & Shipping: Backed by a 1-year OEM factory warranty. In-stock orders ship same business day from our warehouse — get your system back online fast.
