OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG95SAS42100CAAA

This is the factory OEM hot surface igniter (part number LH33ZG001) for the Carrier PG95SAS42100CAAA 95% AFUE packaged gas unit. During every heating cycle, the control board energizes this igniter to glow white-hot and light the main burners. When the igniter cracks, weakens, or fails entirely, the furnace will attempt ignition, fail to establish flame, and enter a safety lockout — leaving you with no heat. Typical symptoms include a furnace that runs the inducer, pauses, then shuts down repeatedly before locking out.

• Part Number & Specs: OEM # LH33ZG001 | 120V hot surface igniter | Silicon nitride element | Lightweight 0.07 lb component with factory-matched plug connector
• OEM vs Generic: This is the genuine Carrier OEM igniter, built to exact factory resistance and thermal cycling tolerances. Generic igniters often use silicon carbide elements that run hotter, are more brittle, and have shorter service lives — risking a repeat failure within one to two seasons.
• Install Difficulty: 2/5 — Always shut off power and gas before servicing. Allow the old igniter to cool completely before touching. Avoid contact with the ceramic element — skin oils cause premature failure. Tools needed: 1/4" nut driver, needle-nose pliers. Disconnect the wire harness, remove the mounting screw, swap the igniter, and reconnect. Verify ignition sequence on first startup.
• Warranty & Shipping: 1-year OEM factory warranty against defects. In stock and ships same business day from our warehouse. Orders placed before 3 PM ship today.
