OEM Carrier Spark Electrode Igniter Assembly 48GS400168 for Model PY3PEA060090AB

This OEM spark electrode igniter assembly is the factory-specified replacement for the Carrier PY3PEA060090AB packaged gas/electric unit. The igniter assembly initiates combustion by generating a high-voltage spark to light the burner. When it fails or degrades, the control board will attempt ignition, detect no flame, and lock out the system — leaving you with no heat and a fault code. Replacing the igniter with a genuine OEM assembly restores reliable first-spark ignition and prevents nuisance lockouts.
