OEM Carrier Spark Electrode Ignitor Assembly 48VL400002 for Model PY3GEAA60090AA

This OEM spark electrode ignitor assembly is the factory-specified replacement for the Carrier PY3GEAA60090AA packaged gas unit. The spark electrode ignitor generates the high-voltage arc that ignites the burner on each heating call. When it fails or degrades, the control board will attempt ignition, detect no flame, and lock out — leaving you with a system that cycles but delivers no heat. Common symptoms include hard lockout fault codes, repeated ignition attempts with no burner flame, or visible cracking and carbon tracking on the ceramic electrode body.

• OEM Part Numbers: 48VL400002 (original) | Superseded by 50HJ403022 — both are factory-genuine Carrier assemblies and direct drop-in replacements
• OEM vs Generic: Genuine Carrier OEM electrodes are manufactured to exact gap tolerances and ceramic insulation ratings. Aftermarket electrodes frequently suffer from inconsistent spark gap dimensions and inferior ceramic compounds, leading to premature cracking under thermal cycling and repeat service calls.
• Install Difficulty: 2/5 — Shut off gas supply and disconnect power at the disconnect box before proceeding. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, and a phone or camera to photograph existing wire routing. The electrode typically mounts to the burner bracket with 1–2 screws and connects via a single high-voltage wire. Verify electrode-to-burner gap per unit service manual before re-firing.
• Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Engineered for the Carrier PY3GEAA60090AA packaged gas/electric unit.
