OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG96VAT60100CAAA

This OEM hot surface igniter (part number LH33ZG001) is the factory-specified replacement for the Carrier PG96VAT60100CAAA 96% AFUE gas furnace. During every heating cycle, the igniter heats to over 2,000°F within seconds to ignite the gas burner. When it fails — typically from hairline cracks or element degradation — the furnace will attempt ignition, fail to sense a flame, and lock out, leaving you with no heat. A fault code indicating a failed ignition sequence is the most common symptom.

• Specs: 120V AC input | Silicon nitride element | Includes mounting bracket and wiring harness | Factory-matched geometry for direct plug-in installation
• OEM vs Generic: This genuine OEM igniter meets Carrier's exact resistance and thermal cycle specifications. Aftermarket alternatives often use silicon carbide elements with wider resistance tolerances, which can cause nuisance lockouts or premature failure in high-efficiency furnaces like the PG96VAT60100CAAA.
• Install Difficulty: 2/5 — De-energize the furnace and allow the 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" hex driver, needle-nose pliers. Disconnect the harness plug, remove the single mounting screw, and reverse for installation. Verify ignition on first call for heat.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
