OEM Carrier Spark Electrode Ignitor (48VL400002) for Model PY3GNA036090AA

This OEM spark electrode ignitor is the factory-specified replacement for the Carrier PY3GNA036090AA packaged gas unit. The ignitor assembly generates the high-voltage spark that ignites the gas burner at the start of every heating cycle. When this component fails, the control board will attempt ignition, detect no flame, and lock out the system — leaving you with a unit that blows cold air or shuts down within seconds of a heat call. Carrier originally listed this part as 48VL400002; the current OEM successor is 50HJ403022, which ships as a direct drop-in replacement.

• Part Numbers: OEM part 48VL400002 | Current OEM successor: 50HJ403022 | Genuine Carrier Factory Authorized Part
• OEM vs Generic: OEM spark electrode assemblies are precision-gapped and rated to exact ignition timing specifications for Carrier controls. Aftermarket electrodes often suffer from gap drift or incompatible ceramic insulators, leading to intermittent ignition faults and repeat service calls.
• Install Difficulty: 2/5 — Disconnect power and gas before servicing. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Note ceramic electrode tip — handle with care to avoid cracking. Photograph wire routing before disconnecting the ignition lead.
• Warranty: 1-year OEM factory warranty against manufacturing defects. In-stock and ships same business day from our warehouse.
