OEM Carrier Spark Electrode Ignitor Assembly 48GS400168 for Model PY2PNB060090AA

This is the factory OEM spark electrode ignitor assembly (part #48GS400168) for the Carrier PY2PNB060090AA packaged gas unit. The spark electrode ignitor initiates combustion by generating a high-voltage spark across the burner assembly at the start of each heating cycle. When this component fails or degrades, the control board will attempt ignition, detect no flame, and lock out — leaving you with a no-heat fault code and a cold building. Replacing the ignitor with a genuine OEM assembly restores factory ignition timing, spark gap geometry, and ceramic insulator integrity.

• Part Number: 48GS400168 | OEM Carrier Factory Authorized Part | Ignitor/Electrode Assembly | 24V control board compatible
• OEM vs Generic: This genuine Carrier OEM ignitor is built to exact factory spark-gap and ceramic insulator specifications. Aftermarket electrodes often ship with inconsistent gap tolerances, leading to repeated lockouts or premature ceramic cracking — especially in high-cycle commercial applications.
• Install difficulty: 2/5 — Shut off gas supply and 24V power before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Photograph all wire harness connections before removal. The electrode assembly drops in directly — no modifications required.
• Warranty: 1-year OEM factory warranty. In stock at NationalHVACParts.com — ships same business day.
