OEM Carrier Spark Electrode Ignitor 48VL400002 for Model PY3GNAA36060AA

This OEM Carrier spark electrode ignitor assembly (part number 48VL400002, superseded by 50HJ403022) is the factory-specified replacement ignitor for the Carrier PY3GNAA36060AA packaged gas unit. The spark electrode ignitor generates the high-voltage arc that ignites the gas burner on each heating call. When it fails, the control board will attempt ignition, detect no flame, and lock out the unit — leaving you with a system that attempts to start but delivers no heat. This is one of the most common causes of a furnace or packaged unit going into hard lockout after 3 ignition tries.

• Specs: L-shaped spark electrode assembly | Ignitor length to L: 1 3/8" | Total assembly length: 2 3/4" | Ground style: L | Country of Origin: USA | Factory-matched OEM fit and arc gap
• OEM vs Generic: OEM electrode igniters maintain precise arc gap geometry and ceramic insulator rating to spec. Aftermarket electrodes often ship with inconsistent gap tolerances, leading to intermittent or weak spark, misfires, and shortened service life.
• Install difficulty: 2/5 — Shut off gas and power before servicing. Tools needed: 1/4" hex driver, flathead screwdriver, needle-nose pliers. Disconnect ignition wire lead, remove mounting bracket screw, swap electrode, reconnect wire. Avoid touching the ceramic insulator with bare hands — skin oils degrade the ceramic and reduce spark efficiency.
• Warranty: 1-year OEM manufacturer warranty against defects. Orders placed by cutoff ship same business day from our warehouse.

Compatibility: Fits Carrier model PY3GNAA36060AA packaged gas/electric units. Note: OEM part number 48VL400002 has been superseded by Carrier part number 50HJ403022 — both are the same factory assembly. Verify part number against your unit's data plate before ordering. Our fitment team is available to confirm compatibility before you buy.
