OEM Carrier Spark Electrode Ignitor Assembly 48GS400168 for Model PY3PEA060115NB

This genuine OEM Carrier spark electrode ignitor assembly (part number 48GS400168) is the factory-authorized replacement for the Carrier PY3PEA060115NB packaged gas unit. The spark electrode ignitor generates the high-voltage arc that ignites the gas burner on every call for heat. When it fails, the control board will attempt ignition, detect no flame, and enter a safety lockout — leaving you with no heat and often a blinking fault code. Replacing the ignitor with the correct OEM part restores reliable ignition and prevents nuisance lockouts caused by worn or cracked electrode tips.
