OEM Carrier Spark Electrode Ignitor 48GS400168 for Model PY2PNB060090NB

This is the OEM factory-specified spark electrode ignitor assembly (part# 48GS400168) for the Carrier PY2PNB060090NB packaged gas unit. The spark electrode ignitor is the component responsible for igniting the gas burner at the start of every heating cycle. When it fails or degrades, the control board will attempt ignition, detect no flame signal, and lock out the system — leaving you with a unit that runs the inducer and gas valve but produces no heat. Symptoms include repeated ignition lockout codes, no spark audible at the burner, or a cracked/fouled electrode tip visible on inspection.
