OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG8JAA048070ADJA

This is the factory OEM hot surface igniter (part number LH33ZG001) for the Carrier PG8JAA048070ADJA packaged gas unit. The igniter is the critical first step in every heating cycle — it glows red-hot to ignite the burner flame upon each call for heat. When it fails, the control board will attempt ignition, find no flame signal, and lock the system out, leaving you with no heat. Common failure symptoms include a furnace that starts the inducer and blower sequence but never produces heat, or a unit that hard-locks after 2–3 ignition retries.

• Specs: 120V | Silicon nitride element | Includes mounting bracket and wire harness | Factory-matched geometry for direct plug-in installation
• OEM vs Generic: OEM igniters are manufactured to exact resistance and thermal-shock tolerances specified by Carrier. Aftermarket igniters often use lower-grade silicon carbide elements that crack prematurely under thermal cycling, leading to repeat failures within one season.
• Install difficulty: 2/5 — Always de-energize the unit before beginning. Never touch the igniter element with bare hands — skin oils cause hot spots that crack the element. Tools needed: 1/4" nut driver, needle-nose pliers. Photograph wiring before disconnecting the harness. Align mounting bracket holes before tightening to avoid stress fractures.
• Warranty: 1-year OEM factory warranty against defects. In-stock orders ship same business day from our warehouse.
