OEM Carrier Hot Surface Igniter (LH33ZS004) for Model PG9MAA024060AFKA

This is the factory OEM hot surface igniter for the Carrier PG9MAA024060AFKA gas furnace, sold under OEM part numbers LH33ZS004 and 329491-401 (Gasket Ignitor kit). The igniter is the first critical component energized on every call for heat — it reaches ignition temperature within seconds, glowing bright orange to light the gas burner. When it fails, the furnace control board will attempt ignition, detect no flame, and lock out, leaving you with no heat. Common failure symptoms include a furnace that runs the inducer and attempts ignition but never fires, or a furnace that enters hard lockout after 3 tries.

• Specs: Silicon carbide flat-style igniter | 120V AC operation | Includes mounting gasket (329491-401) | Factory-matched geometry and resistance for the PG9MAA series
• OEM vs Generic: Genuine Carrier OEM igniters are manufactured to exact resistance tolerances. Off-brand silicon carbide igniters frequently run outside spec, causing nuisance lockouts or premature cracking — especially problematic in cold-climate emergency situations.
• Install difficulty: 2/5 — Power down and lock out the furnace before starting. Tools needed: 1/4" or 5/16" nut driver, needle-nose pliers. Never touch the igniter element with bare hands — skin oils cause hot spots and premature failure. Swap the gasket from the 329491-401 kit during reinstall.
• Warranty: 1-year OEM manufacturer warranty. Ships same business day from our warehouse.
