OEM Carrier Spark Electrode Ignitor 48VL400002 for Model PY3GPAA60090NA

This OEM spark electrode ignitor (part number 48VL400002) is the factory-specified replacement ignition component for the Carrier PY3GPAA60090NA packaged gas unit. The spark electrode generates the high-voltage arc that ignites the gas burners during each heating cycle. When this part fails, the control board will attempt ignition, detect no flame, and trigger a lockout fault — leaving your system with no heat. Common symptoms include a furnace that clicks repeatedly but never lights, or a system that goes into hard lockout after one to three ignition attempts.

• Part Number: 48VL400002 (OEM) | Superseded/current equivalent: 50HJ403022 | Carrier Factory Authorized Part — exact factory fit and specification
• OEM vs Generic: OEM spark electrodes are manufactured to precise gap tolerances and use high-temperature ceramic insulators matched to your unit's ignition module voltage output. Generic electrodes may have inconsistent spark gaps, causing misfires, carbon tracking, or repeated lockouts.
• Install Difficulty: 2/5 — Shut off gas supply and disconnect power before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Photograph wire harness connections before disconnecting. Handle ceramic insulator carefully — do not touch the electrode tip with bare hands.
• Warranty: 1-year OEM factory warranty against manufacturing defects. In stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PY3GPAA60090NA packaged gas/electric rooftop unit. Always verify your unit's data plate and existing part number before ordering to ensure correct fitment. Note that 48VL400002 has been superseded by OEM part 50HJ403022 — both are genuine Carrier parts and are fully interchangeable. Questions about fitment?
