OEM Carrier Spark Electrode Ignitor Assembly 48GS400168 for Model PY3PNA036090NB

This is the genuine OEM Carrier spark electrode ignitor assembly (part #48GS400168), factory-specified for the Carrier PY3PNA036090NB packaged gas/electric unit. The ignitor assembly generates the spark that ignites the gas burner on each heating call. When it fails, the furnace or packaged unit will attempt ignition, fail to light, and enter a safety lockout — leaving you with no heat. Common symptoms include repeated ignition attempts with no flame, a blinking fault code on the control board, or a complete no-heat condition.
