OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG8JAA036045AFJA

This is the factory OEM hot surface igniter (part number LH33ZG001) for the Carrier PG8JAA036045AFJA packaged gas/electric unit. The hot surface igniter is the first component activated during every heat cycle — the control board energizes it to glow at approximately 1,800°F, igniting the gas burner. When the igniter cracks, degrades, or fails to reach operating temperature, the furnace enters a hard lockout: you'll typically see no heat, a blinking fault code, or a unit that attempts ignition once or twice and then shuts down completely. Replacing the igniter is one of the most common and cost-effective furnace repairs available.

• Specs: OEM Part # LH33ZG001 | 120V hot surface igniter | Silicon nitride element | Includes bracket and wiring harness | Factory-matched fit for Carrier PG8J series packaged units
• OEM vs Generic: This is a genuine Carrier OEM igniter — factory-matched resistance and element geometry ensure proper glow temperature and ignition timing. Aftermarket igniters often use mismatched resistance ratings that cause premature burnout or failed ignition sequences.
• Install difficulty: 2/5 — Always de-energize the unit and allow a cool-down period before handling. 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. Disconnect harness, remove mounting screw, swap igniter, reconnect plug, and test ignition sequence.
• Warranty: 1-year OEM factory warranty. In-stock — ships same business day from our warehouse.
