OEM Carrier Hot Surface Igniter (LH33ZG001) for Model PG92SCS60120DAAA

This is the OEM factory-specified hot surface igniter for the Carrier PG92SCS60120DAAA packaged gas unit. On every call for heat, the control board energizes this igniter, allowing the silicon nitride element to reach ignition temperature and light the gas burner. When the igniter fails — due to a hairline crack, contamination, or age-related resistance drift — the furnace will attempt ignition, fail to establish flame, and lock out after 3 attempts. The result: no heat, a blinking fault code, and a cold home.

• Specs: 120V hot surface igniter | Silicon nitride element | Includes mounting bracket and wiring harness | OEM Part # LH33ZG001 | Factory-matched resistance tolerance for reliable cold-weather starts
• OEM vs Generic: This is the genuine Carrier OEM igniter — not an aftermarket substitute. Generic silicon carbide igniters often have mismatched resistance profiles that cause nuisance lockouts or premature failure within one heating season. OEM silicon nitride elements are more durable and crack-resistant than older silicon carbide designs.
• Install Difficulty: 2/5 — Always de-energize the unit at the disconnect before servicing. Never touch the igniter element with bare hands — skin oils cause hot spots that crack the element. Tools needed: 1/4" nut driver, needle-nose pliers, phone camera (photograph wiring harness routing before disconnecting). Confirm fault code is cleared after installation by cycling the thermostat.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before cutoff.
