OEM Carrier Spark Electrode Ignitor Assembly 48GS400168 for Model PY3PPA036090NA

This is the factory OEM spark electrode ignitor assembly for the Carrier PY3PPA036090NA packaged gas/electric unit. The ignitor assembly generates the high-voltage spark that lights the burner at the start of each heating cycle. When this component fails, the unit will attempt ignition, fail to establish flame, and lock out — leaving you with no heat. Typical symptoms include the system clicking repeatedly without lighting, or a hard lockout fault code on the control board requiring a manual reset.
