OEM Carrier Spark Electrode Ignitor (48GS400168) for Model PY3PNA048130AB

This is the factory OEM spark electrode ignitor assembly for the Carrier PY3PNA048130AB packaged unit. The ignitor is the first critical component in the heating sequence — it generates the spark or hot surface charge that ignites the gas burner on every call for heat. When this part fails, the control board will detect a no-light condition and lock out the system after one or more ignition attempts, leaving you with cold air and a fault code. Common symptoms include the inducer coming on, a 30–90 second wait, then a system lockout with no burner ignition.
