OEM Carrier Spark Electrode Ignitor 48GS400168 for Model PY3PEA036060AB

This is the factory-authorized OEM spark electrode ignitor assembly for the Carrier PY3PEA036060AB packaged gas/electric unit. The ignitor is responsible for igniting the gas burners during each heating cycle. When it fails, the system will attempt ignition, fail to establish a flame, and enter a safety lockout — leaving you with no heat. Common symptoms include the unit cycling on and off repeatedly, a no-heat fault code on the control board, or the system running the inducer but never producing a flame.
