OEM Carrier Hot Surface Igniter (LH33ZG001) for Model PG8MAA066135AFJA

This is the factory OEM hot surface igniter for the Carrier PG8MAA066135AFJA packaged gas unit. The igniter is the first active component in every heating cycle — when the control board calls for heat, it energizes the igniter element to reach ignition temperature before the gas valve opens. When this part fails, the furnace will attempt ignition, fail to light, and enter a safety lockout — leaving you with no heat. Common symptoms include repeated soft lockout attempts, an igniter that glows faintly or not at all, or a cracked/contaminated silicon nitride element visible on inspection.

• Specs: 120V AC supply voltage | Silicon nitride element | Factory-matched mounting bracket and wiring harness connector | OEM part number LH33ZG001
• OEM vs Generic: This OEM igniter is manufactured to Carrier's exact resistance and warm-up timing specifications. Generic igniters can vary in warm-up profile, causing gas valve timing mismatches and nuisance lockouts — or premature element failure within one heating season.
• Install difficulty: 2/5 — De-energize the unit completely before servicing. Tools needed: 1/4" nut driver, flat-head screwdriver, needle-nose pliers. Critical: never touch the silicon nitride element with bare hands — skin oils cause hot spots and drastically shorten element life. Reconnect harness plug until it clicks, then verify ignition sequence on first call for heat.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.
