OEM Carrier Hot Surface Igniter Replacement Kit 331930-751 for Model PG8JAA048090ABJA

This is the factory-specified OEM hot surface igniter replacement kit for the Carrier PG8JAA048090ABJA gas furnace. The hot surface igniter is the component responsible for igniting the gas burner at the start of every heat cycle. When it fails, the furnace will attempt ignition, fail to light, and enter safety lockout — leaving you with no heat. Common symptoms include the inducer running normally but the burner never lighting, or the furnace locking out after one to three ignition attempts.
