OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG92SCS60100CAAA

This is the genuine OEM hot surface igniter for the Carrier PG92SCS60100CAAA packaged gas unit. The igniter is the first component activated during every heating cycle — when your thermostat calls for heat, the control board energizes this silicon nitride element to glowing temperature, igniting the gas burner within seconds. When the igniter fails, the furnace enters a hard lockout after one or more failed ignition attempts, leaving you with no heat. Common symptoms include a blinking fault code on the control board, the burner never lighting despite the inducer running, or a visibly cracked igniter element.

• OEM Part Number: LH33ZG001 | Carrier-genuine factory replacement | Nitride hot surface element rated for 120V operation
• OEM vs Generic: OEM igniters are manufactured to exact resistance and watt-density specs for the PG92SCS60100CAAA control board's timed ignition sequence. Off-brand igniters may heat too slowly or too fast, causing repeated lockouts or premature element failure.
• Install Difficulty: 2/5 — De-energize the unit at the disconnect before starting. Never touch the nitride element with bare hands — skin oils create hot spots that crack the element under thermal cycling. Tools needed: 1/4" nut driver, needle-nose pliers. Disconnect wiring harness, remove mounting screw, swap igniter, reconnect plug, and verify ignition on first call for heat.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.
