OEM Carrier Spark Electrode Ignitor Assembly (48GS400168) for Model PY3PNA060115AA

This is the factory OEM spark electrode ignitor assembly, part number 48GS400168, designed as the direct replacement for the Carrier PY3PNA060115AA packaged gas unit. The ignitor assembly generates the high-voltage spark required to ignite the gas burner on each heating cycle. When this component fails, the control board will attempt ignition, detect no flame, and lock out the system — leaving you with a furnace that attempts to start but never produces heat. This is one of the most common causes of a no-heat service call on Carrier packaged gas equipment.
