OEM Carrier Spark Electrode Ignitor (48GS400168) for Model PY3PPA042060AA

This is the genuine OEM spark electrode ignitor assembly for the Carrier PY3PPA042060AA packaged unit. The spark electrode is responsible for igniting the gas burner during each heating cycle. When it fails, the control board will attempt ignition, detect no flame, and enter a safety lockout — leaving you with a system that calls for heat but never delivers it. Common symptoms include repeated ignition attempts followed by a blinking fault code, or a complete no-heat condition.
