OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG8JAA066135AFJA

This is the genuine OEM hot surface igniter (part number LH33ZG001), factory-specified for the Carrier PG8JAA066135AFJA packaged gas unit. During every heating cycle, the control board energizes the igniter to reach ignition temperature before opening the gas valve. When the igniter fails — due to cracking, contamination, or age-related degradation — the furnace will attempt ignition, fail to light the burner, and go into safety lockout, leaving you with no heat. Replacing this part with the correct OEM component restores reliable ignition and prevents repeat lockout faults.

• Specs: OEM Part # LH33ZG001 | Includes mounting bracket and wiring harness | Silicon nitride element | Factory-matched geometry for direct plug-in replacement
• OEM vs Generic: This is a genuine Carrier OEM igniter — not an aftermarket substitute. OEM igniters are manufactured to exact watt density and resistance specifications. Generic igniters can vary in element geometry and electrical draw, leading to premature failure or inconsistent ignition timing.
• Install Difficulty: 2/5 — De-energize the unit and allow the igniter to cool completely before handling. Never touch the ceramic element with bare hands — skin oils accelerate cracking under thermal stress. Tools needed: 1/4" nut driver, Phillips screwdriver, needle-nose pliers. Disconnect the harness plug, remove the mounting screw, swap the igniter, and reconnect. Verify ignition sequence on first call for heat.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
