OEM Carrier Spark Electrode Ignitor 48VL400002 for Model PY3GNA042060NA

This is the factory OEM spark electrode ignitor assembly for the Carrier PY3GNA042060NA packaged gas unit. The spark electrode ignitor is responsible for generating the high-voltage arc that lights the burner on every call for heat. When this component fails or degrades, the control board will attempt ignition, detect no flame, and lock the system out — leaving you with a no-heat call and a blinking fault code. Replacing the ignitor with a factory-matched OEM part restores reliable ignition and prevents nuisance lockouts caused by weak or misfiring spark.

• Part Number: OEM Carrier 48VL400002 | Current superseding part: 50HJ403022 | Spark electrode ignitor assembly | Factory-matched ignition geometry for PY3GNA042060NA burner deck
• OEM vs Generic: OEM spark electrodes maintain precise electrode gap and ceramic insulator integrity as engineered for the burner. Generic alternatives frequently use substandard ceramics that crack under thermal cycling, causing intermittent misfire and repeat service calls.
• Install Difficulty: 2/5 — Shut off gas and 24V power at disconnect before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Disconnect ignition wire lead, remove mounting screws, swap electrode, reconnect lead — confirm ignition on first call for heat before buttoning up the cabinet.
• Warranty: 1-year OEM manufacturer warranty against defects. In stock and ships same business day from our warehouse.
