OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG92SBS48080BBAA

This is the factory OEM hot surface igniter (part number LH33ZG001) for the Carrier PG92SBS48080BBAA packaged gas unit. The igniter is the first component energized during every heating cycle — it glows to ignition temperature within seconds, igniting the gas burner on demand. When it fails, the control board detects no flame establishment and triggers a hard lockout, leaving you with a system that attempts to start, fails, then shuts down — commonly after 3 ignition attempts. A cracked, contaminated, or open-circuit igniter element is the #1 cause of no-heat calls on this platform.

• Specs: 120V hot surface igniter | Silicon nitride element | Includes bracket and wiring harness | Factory-matched geometry for direct drop-in fit on PG92SBS48080BBAA
• OEM vs Generic: OEM igniters are manufactured to exact factory resistance and thermal-shock tolerances. Aftermarket igniters often run outside spec resistance ranges, causing nuisance lockouts or premature cracking — especially during cold-start cycles.
• Install difficulty: 2/5 — De-energize the unit at the disconnect before beginning. Never touch the silicon nitride element with bare hands — skin oils cause hot spots and premature failure. Tools needed: 1/4" nut driver, flat-blade screwdriver. Disconnect harness plug, remove mounting screw, swap igniter, reconnect plug, and verify ignition sequence on first call for heat.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
