OEM Carrier Spark Electrode Ignitor 48GS400168 for Model PY1PPB048130NBAA

This is the genuine OEM spark electrode ignitor assembly for the Carrier PY1PPB048130NBAA packaged gas unit. The ignitor is responsible for initiating combustion each heating cycle — when it fails, the control board will attempt ignition, detect no flame, and lock out the system. Common symptoms include a no-heat call with the inducer running, repeated ignition attempts followed by lockout, or an error code indicating ignition failure. Replacing this OEM ignitor restores reliable first-try ignition and protects the heat exchanger from unburned gas exposure.
