OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG9MAB024040LBSA

This is the genuine OEM hot surface igniter (part number LH33ZG001), factory-specified for the Carrier PG9MAB024040LBSA gas furnace. The igniter is the first active component in every heating cycle — it glows to ignition temperature within seconds to light the burner. When it fails, the furnace control board will attempt ignition, detect no flame, and lock out, leaving you with no heat. Common symptoms include repeated ignition attempts followed by a lockout fault code, or a furnace that runs the inducer and gas valve but never produces a flame.
