OEM Carrier Spark Electrode Ignitor 48VL400002 for Model PY4GNAA60115AA

This OEM spark electrode ignitor is the factory-specified replacement for the Carrier PY4GNAA60115AA packaged gas unit. The spark electrode ignitor generates the high-voltage spark needed to ignite the gas burner at the start of each heating cycle. When the ignitor fails or cracks, the control board will attempt ignition, detect no flame, and lock out the system — leaving you with a no-heat call and a fault code. This part is also cross-referenced under the updated Carrier OEM part number 50HJ403022, which supersedes 48VL400002 and also replaces 50HJ401430 and 50HJ400608.

• Specs: Spark electrode ignitor assembly | OEM part number 48VL400002 (superseded by 50HJ403022) | Factory-matched spark gap and mounting geometry | Includes bracket and lead wire assembly
• OEM vs Generic: OEM electrodes maintain precise spark gap tolerances calibrated to your unit's ignition module. Aftermarket electrodes with loose tolerances can cause intermittent ignition failures, repeated lockouts, and accelerated ignition module wear.
• Install difficulty: 2/5 — Turn off gas supply and 24V/line voltage power before starting. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Photograph existing wire routing and electrode position before removal. Handle electrode tip carefully — contamination from skin oils can affect spark quality.
• Warranty: 1-year OEM factory warranty against manufacturing defects. In stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PY4GNAA60115AA packaged gas/electric rooftop unit. Verify your existing OEM part number on the unit's data plate or wiring diagram before ordering. Note that 48VL400002 has been superseded by Carrier part number 50HJ403022 — both are functionally identical. Questions about fitment?
