OEM Carrier Hot Surface Igniter Replacement Kit 331930-751 for Model PG8JAA024045ABJA

The Carrier 331930-751 Hot Surface Igniter Kit is the factory-specified OEM replacement for Carrier PG8JAA024045ABJA gas furnaces. The hot surface igniter is a critical component in the furnace ignition sequence — it heats to over 1,800°F within seconds to ignite the gas burner. When the igniter fails or cracks, the furnace control board detects no ignition and triggers a safety lockout, leaving you with no heat. Symptoms include the furnace attempting to start, failing after 1–3 tries, and locking out entirely.

• Specs: 120V AC | Silicon Nitride flat igniter | Voltage range: 98–132 VAC | Time to 1,800°F: <17 seconds @ 120V | Steady-state current: 0.8–2.0 amps | Cold resistance: 34–64 Ohms @ 75°F | Replaces legacy part LH33ZS004
• Kit Includes: Silicon nitride igniter element, mounting bracket, OEM connector plug, and high-temperature wire nuts — everything needed for a complete, code-correct installation with no splicing required.
• OEM vs Generic: This OEM kit is factory-matched to exact voltage and resistance tolerances for the PG8JAA024045ABJA. Generic igniters often ship without brackets or correct connectors, and off-spec resistance values can cause nuisance lockouts or premature burnout.
• Install Difficulty: 3/5 — Requires shutting off gas and power before starting. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, multimeter (to verify cold resistance). Do NOT touch the igniter element with bare hands — skin oils cause hot spots and early failure. Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse.
