OEM Carrier Silicon Nitride Hot Surface Igniter LH33ZG001 for Model PG9MAB048060LBSA

This OEM hot surface igniter (part number LH33ZG001) is the factory-specified replacement for the Carrier PG9MAB048060LBSA packaged gas unit. During every call for heat, the control board energizes this igniter to glow at several hundred degrees, igniting the gas burner within seconds. When the igniter fails — whether from thermal fatigue, physical cracking, or oil contamination — the furnace will attempt ignition, fail to light, and enter a hard lockout, leaving you with no heat. Symptoms include a no-heat fault code, a glowing-but-no-ignition sequence, or a unit that cycles three times and shuts down entirely.

• Specs: Silicon nitride element | 120V | Room temperature resistance: 45–70 Ohms | Steady-state current: 4.25–4.75 Amps @ 132V | Element length: 3/16" | Total length with base: 2-1/2" | Wire length: 9-1/4" | Bracket length: 1-1/4" | Manufactured in Japan by Kyocera
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part, manufactured to exact dimensional and electrical tolerances for the PG9MAB048060LBSA. Generic igniters may use lower-grade silicon nitride with inconsistent resistance values, leading to nuisance lockouts or premature element failure.
• Install difficulty: 2/5 — Turn off gas supply and disconnect power before servicing. Tools needed: 1/4" nut driver, needle-nose pliers. Handle igniter by the ceramic base ONLY — skin oils on the silicon nitride element cause hot spots and early failure. Photograph wiring before disconnecting the harness plug.
• Warranty: 1-year OEM manufacturer warranty against defects. In-stock and ships same business day from our warehouse.
