OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG8MAA048070ADJA

This is the factory OEM hot surface igniter (part number LH33ZG001) for the Carrier PG8MAA048070ADJA packaged gas unit. The igniter is the first critical link in the heating sequence — when the thermostat calls for heat, the control board energizes the igniter element to glow at temperatures exceeding 1,800°F, igniting the gas burner. A failed igniter is one of the most common causes of a no-heat call: the furnace will attempt ignition, fail to sense flame, and lock out — often displaying a fault code on the control board. If your unit starts the heating cycle but shuts down before producing heat, or the igniter element shows visible cracks, this is your part.

• Specs: 120V hot surface igniter | Silicon element | Includes bracket and wiring harness | Factory-matched geometry and resistance for Carrier PG8MAA series packaged units
• OEM vs Generic: OEM igniters from Carrier are manufactured to exact resistance and thermal-shock tolerances. Aftermarket igniters frequently have mismatched resistance values or inferior element compositions, leading to premature cracking and repeat failures — especially in high-cycle commercial or residential applications.
• Install Difficulty: 2/5 — Shut off power and gas before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Never touch the igniter element with bare hands — skin oils cause hot spots that crack the element under thermal stress. Wear clean gloves or handle by the bracket only.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
