OEM Carrier Spark Electrode Igniter (48VL400002) for Model PY3GEAA36090AA

This is the OEM factory-specified spark electrode igniter for the Carrier PY3GEAA36090AA packaged gas heating system. The spark electrode igniter generates the high-voltage arc that ignites the gas burner on each heating call. When this component fails or degrades, the control board will attempt ignition, detect no flame, and trigger a lockout fault — leaving you with a system that runs the inducer and gas valve but never produces heat. Common symptoms include repeated ignition attempts followed by a hard lockout, error codes indicating ignition failure, or visible carbon tracking and cracked ceramic on the electrode tip.

• Specs: OEM Part# 48VL400002 | Spark Electrode Igniter | Factory-direct replacement | Carrier-approved ceramic and electrode tip geometry for precise spark gap
• OEM vs Generic: This OEM igniter is manufactured to exact Carrier tolerances for spark gap, ceramic insulation grade, and mounting bracket dimensions. Aftermarket igniters may use inferior ceramics prone to cracking under thermal cycling, leading to premature failure and nuisance lockouts.
• Install Difficulty: 2/5 — Shut off gas supply and disconnect power before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Photograph existing electrode orientation and wire routing before removal. Handle ceramic insulator with care — do not touch electrode tip with bare hands (skin oils degrade ceramic).
• Warranty: 1-year OEM manufacturer warranty. In-stock and ships same business day from our warehouse.
