OEM Carrier Hot Surface Igniter (LH33ZS004) for Model PG9MAA048060AFKA

This is the factory OEM hot surface igniter assembly for the Carrier PG9MAA048060AFKA gas furnace. Referenced under two Carrier part numbers — LH33ZS004 (Hot Surface Ignitor) and 329491-401 (Gasket Ignitor, the mounting gasket included in the assembly) — this is the complete, drop-in replacement kit as shipped from the factory. The igniter heats to ignition temperature within seconds on every call for heat, glowing bright orange to light the burner. When it fails — typically due to hairline cracks from thermal cycling or age — the furnace control board will attempt ignition, fail to sense flame, and lock out the unit, leaving you with a no-heat call.

• OEM Part Numbers: LH33ZS004 (Hot Surface Ignitor) | 329491-401 (Gasket Ignitor) — complete factory assembly with mounting gasket included
• OEM vs Generic: OEM igniters are manufactured to exact Carrier resistance and thermal mass specifications. Off-brand silicon carbide igniters often crack prematurely or fail to reach full ignition temperature, causing nuisance lockouts and repeat service calls.
• Install Difficulty: 2/5 — Disconnect power and gas before servicing. Tools needed: 1/4" nut driver, needle-nose pliers. Never touch the igniter element with bare hands — skin oils cause premature failure. Use gloves or handle only by the wiring harness and bracket. Photograph wiring before disconnecting.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
