OEM Carrier Hot Surface Igniter for Model PG8JAA024070ADJA Furnace

This is the factory OEM hot surface igniter (Part # LH33ZG001) for the Carrier PG8JAA024070ADJA gas furnace. The hot surface igniter is the critical first step in every heating cycle — the control board energizes it to glow at over 1,800°F, igniting the gas burners. When this part fails, the furnace will attempt ignition, fail to light, and lock out — leaving you with no heat. Common symptoms include the inducer running normally, the igniter failing to glow red-orange, followed by a hard lockout or repeated retry cycles.
