OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG8MAA036070AFJA

This is the factory OEM hot surface igniter (part# LH33ZG001) for the Carrier PG8MAA036070AFJA packaged gas unit. The hot surface igniter is the critical first step in every heating cycle — the control board energizes the igniter element to glow orange-hot, igniting the gas burner within seconds. When the igniter fails, the furnace will attempt ignition, fail to light, and enter a hard lockout — leaving you with no heat. Common symptoms include a no-heat call where the inducer runs and the gas valve clicks but there's no flame, or repeated ignition fault codes on the control board.

• OEM Part Number: LH33ZG001 | 120V rated | Silicon nitride element | Factory-matched geometry and connector for direct plug-in replacement
• OEM vs Generic: This is a genuine Carrier OEM igniter, manufactured to exact factory resistance and heat-up time specifications. Aftermarket igniters frequently ship with incorrect resistance values or fragile silicon carbide elements, leading to premature cracking and repeat service calls.
• Install Difficulty: 2/5 — Always de-energize the unit at the disconnect before servicing. Never touch the igniter element with bare hands — skin oils cause hot spots and premature failure. Tools needed: 1/4" nut driver, needle-nose pliers. Disconnect the harness plug, remove the single mounting screw, swap the igniter, and reconnect. 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.
