OEM Carrier Spark Electrode Ignitor (48GS400168) for Model PY2PEB042090AB

This is the genuine OEM Carrier spark electrode ignitor assembly, factory part number 48GS400168, engineered as the direct replacement for the Carrier PY2PEB042090AB packaged unit. The spark electrode ignitor is a critical component in the gas ignition sequence — it generates the high-voltage spark that ignites the burners on each heating cycle. When the ignitor fails, the control board will attempt ignition, detect no flame, and lock out the system, leaving you with no heat and a blinking fault code.
