OEM Carrier Spark Electrode Ignitor (48GS400168) for Model PY3PPA060090NA

This is the genuine OEM Carrier spark electrode ignitor assembly, part number 48GS400168, factory-specified for the Carrier PY3PPA060090NA packaged unit. The spark electrode ignitor is the component responsible for generating the electrical arc that ignites the gas burner on each call for heat. When it fails, the control board will attempt ignition, detect no flame, and lock out the system — leaving you with no heat and a fault code on the board. Common symptoms include repeated ignition attempts without burner light-off, a visible cracked or fouled electrode tip, or an error code indicating ignition failure.

OEM electrodes are manufactured to exact gap, ceramic, and connector specifications for your unit, ensuring consistent spark timing and reliable ignition cycle after cycle.
