OEM Carrier Hot Surface Igniter (LH33ZG001) for Model PG92SBS48100CAAA

This is the factory OEM hot surface igniter for the Carrier PG92SBS48100CAAA packaged gas unit. The igniter is the first component activated on every call for heat — the control board energizes it to reach ignition temperature (~2,500°F), which then lights the gas burner. When the igniter fails, the furnace or packaged unit will attempt ignition, fail to establish flame, and lock out — leaving you with no heat. Common symptoms include a hard lockout fault code, a visibly cracked igniter element, or a system that fires the inducer but never lights the burner.

• Specs: 120V AC | Silicon nitride element | Includes mounting bracket and wiring harness | OEM part number LH33ZG001 | Factory-matched fit for Carrier packaged gas units
• OEM vs Generic: OEM silicon nitride igniters carry the exact resistance profile and element geometry specified by Carrier engineering. Generic igniters often deviate in resistance or mounting angle, causing nuisance lockouts or premature cracking at heat cycling stress points.
• Install difficulty: 2/5 — De-energize and lock out the unit before beginning. Tools needed: 1/4" nut driver, flat-head screwdriver, needle-nose pliers. Never touch the igniter element with bare hands — skin oils cause hot-spot cracking. Photograph existing wiring before disconnecting the harness. Confirm no cracks after seating in bracket before powering up.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
