OEM Carrier Spark Electrode Ignitor 48GS400168 for Model PY3PNA048115AB

This is the genuine OEM spark electrode ignitor assembly for the Carrier PY3PNA048115AB packaged heating and cooling unit. The spark electrode ignitor is the first component in the heating sequence — it generates the high-voltage spark that lights the gas burner on every call for heat. When this part fails, the control board will attempt ignition, sense no flame, and lock out the unit, resulting in a no-heat call. Common symptoms include the system cycling through ignition attempts and shutting down, or a complete failure to produce any heat even with a functional gas supply and control board.
