OEM Carrier Spark Electrode Ignitor (48GS400168) for Model PY3PNA048130NA

This is the factory OEM spark electrode ignitor assembly for the Carrier PY3PNA048130NA packaged gas unit. The ignitor is the first critical link in the ignition sequence — when the control board calls for heat, it energizes the ignitor to generate the spark that lights the burner. A failed ignitor typically causes the unit to enter a hard lockout after one or two failed ignition attempts, leaving you with no heat and a flashing fault code. Replacing it with the correct OEM part restores reliable cold-start performance and prevents repeat service calls.
