OEM Carrier Hot Surface Igniter Replacement Kit 331930-751 for Model PG8JAA024045AAJA

This is the genuine OEM hot surface igniter replacement kit (part #331930-751) factory-specified for the Carrier PG8JAA024045AAJA gas furnace. The hot surface igniter is the first critical component in your furnace's ignition sequence — it heats to over 1800°F within seconds to ignite the gas burners. When it fails, the furnace control board will attempt ignition, detect no flame, and lock out, leaving you with no heat. Common symptoms include repeated no-heat calls, a flashing fault code for ignition failure, or a furnace that starts briefly and then shuts down before establishing a flame.

• Specs: 120V AC | Silicon Nitride element | Reaches 1800°F in under 17 seconds @ 120 VAC | Steady-state current: 0.8–2.0 amps | Cold resistance: 34–64 Ohms @ 75°F | Replaces OEM part LH33ZS004 in 33" tall furnace models
• Complete Kit Includes: Silicon nitride igniter element, mounting bracket, OEM-matched connector, and high-temperature wire nuts — everything needed for a clean, code-compliant installation with no additional sourcing required
• OEM vs Generic: This factory OEM part is precision-matched to the Carrier PG8JAA024045AAJA's control board timing and voltage tolerances. Generic igniters often vary in resistance and warm-up time, causing nuisance lockouts or premature element failure. OEM silicon nitride construction is far more durable and crack-resistant than older silicon carbide designs.
• Install Difficulty: 3/5 — Gas appliance repair; turn off gas supply and 120V power before beginning. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (to verify cold resistance 34–64 Ohms). Do not touch the silicon nitride element with bare hands — skin oils degrade the element at operating temperatures. Confirm fault code reset after installation. Professional installation recommended.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before cutoff.
