OEM Carrier Spark Electrode Igniter for Model PY3GNA036090AB

This OEM spark electrode igniter is the factory-specified replacement for the Carrier PY3GNA036090AB packaged unit. The igniter initiates combustion by generating a high-voltage spark to light the burner assembly. When it fails or cracks, the control board will attempt ignition, detect no flame, and lock the system out — leaving you with a blower running but no heat. Common symptoms include repeated ignition attempts, a no-heat / lockout fault code, or a visibly cracked or burned electrode tip.

• Specs: Spark electrode design | OEM part numbers: 48VL400002 (primary) / 48GS400168 (alternate) | Factory-matched fit and ignition gap for Carrier PY3GNA036090AB
• OEM vs Generic: This is a genuine OEM Carrier igniter — exact electrode geometry, correct spark gap, and ceramic insulator rating. Generic units may feature inconsistent spark gaps or inferior ceramic insulators, increasing the risk of misfire or premature cracking.
