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.

  • Kit Includes: Silicon nitride igniter element, OEM mounting bracket, OEM connector, and high-temperature wire nuts — everything needed for a complete, code-compliant swap. Replaces legacy part number LH33ZS004 in 33" tall furnace configurations.

Generic igniters may vary in element geometry, resistance range, and connector fit — risking mis-ignition, nuisance lockouts, or premature failure. OEM is always the right call for a reliable, long-term fix.

Tools needed: ¼" nut driver, needle-nose pliers, and a multimeter (to verify cold resistance before installation). Always disconnect power and shut off the gas supply before beginning. Follow all local codes and manufacturer safety instructions.
