OEM Carrier Spark Electrode Ignitor Assembly 48VL400002 for Model PY4GEAA48115AA

This OEM Carrier spark electrode ignitor assembly (part number 48VL400002, now superseded by 50HJ403022) is the factory-specified replacement for the Carrier PY4GEAA48115AA packaged gas/electric unit. The ignitor generates the high-voltage spark that ignites the gas burner on every call for heat. When it fails, the control board will attempt ignition, detect no flame, and lock out the system — leaving you with a blinking fault code, no heat, and a cold building.

• Part Number: 48VL400002 (OEM superseded by 50HJ403022) | Spark electrode ignitor assembly | Factory-direct OEM specification | Includes electrode rod and bracket
• OEM vs Generic: OEM ignitor assemblies are precision-gapped at the factory to match the burner geometry of your Carrier unit. Off-brand electrodes often feature inconsistent gap spacing and inferior ceramic insulators, leading to misfires, nuisance lockouts, and premature failure.
• Install Difficulty: 2/5 — Straightforward swap on most technicians. Tools needed: 1/4" and 5/16" nut driver, flat-head screwdriver, needle-nose pliers. Always shut off gas supply and disconnect power before servicing. Photograph wiring and electrode orientation before removal.
• Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our stocked warehouse when ordered before cutoff.

Compatibility: Designed for the Carrier PY4GEAA48115AA packaged rooftop/gas-electric unit. Note that OEM part 48VL400002 has been superseded — this listing ships the current authorized replacement 50HJ403022, which is a direct form-fit-function substitute. Verify your unit's data plate and existing ignitor configuration before ordering. Our fitment team is available to confirm compatibility before you buy — no guesswork required.
