OEM Carrier Spark Electrode Ignitor 48GS400168 for Model PY3PPA060090AB

This is the genuine OEM Carrier spark electrode ignitor assembly (part number 48GS400168), the factory-specified replacement for the Carrier PY3PPA060090AB packaged gas unit. The ignitor initiates combustion by generating a precisely timed electrical spark at the burner assembly. When this component fails, the control board will attempt ignition, detect no flame, and lock out the system — leaving you with no heat and a flashing fault code on the board. Attempting a heating cycle that ends in lockout after 2–3 tries is the most common symptom of a failed spark electrode.
