OEM Carrier Hot Surface Igniter Replacement Kit 331930-751 for Model PG8JAA066110AAJA

This is the genuine OEM hot surface igniter replacement kit (part number 331930-751) for the Carrier PG8JAA066110AAJA gas furnace. The hot surface igniter is the component responsible for lighting the gas burners on every heating cycle. When it fails, the furnace control board will attempt ignition, detect no flame, and enter a safety lockout — leaving you with no heat. Common symptoms include the furnace cycling on, running the inducer, then shutting down without ever producing a flame, often accompanied by a blinking fault code on the control board.

• Part Number: 331930-751 | Replaces legacy part LH33ZS004 in compatible 33" tall furnace models
• Specs: 120V AC hot surface ignition | Silicon nitride element (more durable than silicon carbide) | Kit includes mounting bracket, OEM connector, and high-temperature wire nuts for a complete, no-improvisation installation
• OEM vs Generic: This genuine Carrier OEM kit is factory-calibrated to the exact voltage and heat-up timing required by the PG8JAA066110AAJA control board. Generic igniters often vary in cold resistance and warm-up time, risking nuisance lockouts or premature element cracking.
• Install Difficulty: 2/5 — Turn off gas and power before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Do not touch the silicon nitride element with bare hands — skin oils cause hot spots and early failure. Use the included bracket and harness for a direct swap.
• Warranty: 1-year OEM factory warranty. In stock — ships same business day from our warehouse.
