OEM Carrier Hot Surface Igniter Kit 331930-751 for Model PG8JAA048110ABJA

This OEM hot surface igniter kit (part number 331930-751) is the factory-specified replacement for the Carrier PG8JAA048110ABJA gas furnace. The hot surface igniter is a critical ignition component — it heats to approximately 1,800°F to ignite the gas burners on each heating cycle. When it fails, the furnace control board will attempt ignition, detect no flame, and lock out the system, leaving you with no heat. Common failure symptoms include the furnace going through a full ignition sequence with no burner flame, a visible crack in the igniter element, or a measured open circuit (infinite resistance) across the igniter terminals.

• Specs: OEM hot surface igniter replacement kit | Silicon nitride element (preferred over silicon carbide for longevity) | Factory-matched electrical resistance and wattage | Includes mounting hardware and wiring connector for drop-in installation
• OEM vs Generic: This OEM kit is manufactured to exact Carrier factory tolerances. Generic igniters frequently deviate in wattage and element geometry, leading to inconsistent ignition, premature cracking, and shortened service life — especially in cold-start conditions.
• Install Difficulty: 2/5 — Always power down and lock out the furnace before beginning. Tools needed: 1/4" nut driver, small flat-head screwdriver, needle-nose pliers, and a multimeter to confirm open circuit on the failed igniter. Never touch the igniter element with bare hands — skin oils cause hot spots and premature failure. Use gloves or handle by the mounting bracket only.
• Warranty: 1-year OEM factory warranty. Orders placed before cutoff ship same business day from our warehouse.
