OEM Carrier Spark Electrode Ignitor Assembly (48GS400168) for Model PY2PNB048090AA

This is the genuine OEM spark electrode ignitor assembly for the Carrier PY2PNB048090AA packaged gas unit. The ignitor assembly initiates the combustion cycle by generating a spark across two electrodes to light the burner. When this component fails, the furnace or packaged unit will attempt ignition, fail to establish a flame, and enter a safety lockout — leaving you with no heat. Common symptoms include repeated ignition attempts followed by a lockout fault code, a distinct clicking without flame, or a complete no-heat condition.
