OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG92SBS30040AAAA

This is the factory OEM hot surface igniter (part number LH33ZG001) for the Carrier PG92SBS30040AAAA packaged gas unit. The igniter is the first component activated in the heating sequence — the control board energizes it to reach ignition temperature, which then lights the gas burner. When it fails, the furnace will attempt ignition one to three times and then lock out, leaving you with no heat and a fault code. Common symptoms include a furnace that runs its inducer motor but never lights, or repeated ignition lockout error codes on the control board.

• Specs: 120V hot surface igniter | Silicon nitride element | Factory-matched plug and harness connector | OEM part number LH33ZG001 | Weight: 0.07–0.10 lbs
• OEM vs Generic: OEM igniters are manufactured to Carrier's exact voltage draw and warm-up timing specs. Aftermarket igniters often vary in resistance and geometry, risking premature cracking, mistimed ignition, or repeated lockouts — especially in cold-weather startup conditions.
• Install difficulty: 2/5 — Shut off power and gas before beginning. Tools needed: 1/4" nut driver, needle-nose pliers. Never touch the igniter element with bare hands — skin oils cause hot spots that crack the element. Photograph wire connections before disconnecting, then reverse the removal process to install.
• Warranty: 1-year OEM factory warranty. In stock — ships same business day from our warehouse.
