OEM Carrier Spark Electrode Ignitor 48VL400002 for Model PY4GNAB48130AA

This OEM spark electrode ignitor is the factory-specified replacement for the Carrier PY4GNAB48130AA packaged gas/electric unit. The spark electrode assembly generates the high-voltage arc that ignites the burner on each heating call. When it fails or cracks, the control board will attempt ignition, detect no flame, and lock out — leaving you with no heat. Common symptoms include repeated ignition attempts followed by a lockout fault code, a visible crack in the ceramic insulator, or carbon tracking on the electrode tip.
