OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG9UAA060100AASA

This is the factory OEM hot surface igniter (part number LH33ZG001) for the Carrier PG9UAA060100AASA packaged gas unit. During every call for heat, the control board energizes this igniter to glow at approximately 2,000°F, igniting the gas burner within seconds. When the igniter fails — typically due to hairline cracks in the element or gradual resistance drift — the furnace will attempt ignition, fail to sense a flame, and lock out after one to three tries. You'll notice the system blowing only cold air or displaying a diagnostic fault code related to ignition failure.

• Part Number: LH33ZG001 | OEM Carrier replacement | 120V AC | Silicon nitride element for longer service life vs. silicon carbide
• OEM vs Generic: This factory-matched OEM igniter meets Carrier's exact resistance and thermal-shock specifications. Off-brand igniters often use lower-grade silicon carbide, which is more brittle, more prone to cracking, and may cause repeated nuisance lockouts within a single heating season.
• Install Difficulty: 2/5 — Shut off power and gas before beginning. Tools needed: 1/4" nut driver, flathead screwdriver, needle-nose pliers. Critical: Never touch the igniter element with bare hands — skin oils cause hot spots that crack the element prematurely. Use gloves or handle by the bracket only.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.
