OEM Carrier Spark Electrode Igniter 48VL400002 for Model PY3GEAA60090NA

This is the factory OEM spark electrode igniter for the Carrier PY3GEAA60090NA gas furnace. The spark electrode igniter is a critical component in the ignition sequence — it generates the high-voltage spark that ignites the gas burner at the start of each heating cycle. When it fails, the control board will detect an unsuccessful ignition attempt and trigger a safety lockout, leaving your system with no heat. Common symptoms of a failed igniter include repeated ignition attempts with no flame establishment, a hard fault lockout code, or a visibly cracked or carbon-fouled electrode tip.

• Specs: Spark electrode igniter assembly | OEM Part Number 48VL400002 | Factory-matched mounting configuration and electrode gap for precise spark delivery
• OEM vs Generic: This is the genuine Carrier factory part, ensuring exact electrode geometry, gap specification, and ceramic insulator grade. Aftermarket igniters can suffer from inconsistent spark gap, inferior ceramics prone to cracking, and misfiring — leading to repeat lockouts and unnecessary service calls.
• Install Difficulty: 2/5 — Shut off gas supply and 120V power before servicing. Tools needed: Phillips-head screwdriver, 1/4" nut driver, and needle-nose pliers. Disconnect the igniter wiring harness, remove the mounting fastener, swap in the new electrode, and restore wiring. Always verify the spark gap matches the original before restoring power.
• Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship the same business day from our warehouse.
