OEM Carrier Spark Electrode Ignitor 48GS400168 for Model PY2PPB048115AB

This is the factory-authorized OEM spark electrode ignitor assembly (part# 48GS400168) designed as a direct replacement for the Carrier PY2PPB048115AB packaged gas unit. The spark electrode ignitor generates the high-voltage spark that ignites the gas burners on each call for heat. When this component fails, the control board will attempt ignition, detect no flame, and lock out the system — leaving you with a furnace that powers on but produces no heat. A failed ignitor is one of the most common causes of no-heat service calls on Carrier gas pack systems.

• OEM vs Generic: This genuine Carrier OEM ignitor is manufactured to exact factory tolerances for spark gap, electrode material, and connector fit. Generic igniters may produce weak or inconsistent spark, leading to repeat lockouts, nuisance service calls, and premature heat exchanger stress.
