OEM Carrier Spark Electrode Ignitor 48VL400002 for Model PY4GNAB30060AA

This is the OEM factory-specified spark electrode ignitor for the Carrier PY4GNAB30060AA packaged gas/electric unit. The spark electrode ignitor generates the high-voltage arc that lights the burner on each call for heat. When this component fails or becomes fouled, the control board will attempt ignition, detect no flame, and lock out the system — leaving you with a unit that powers on but produces no heat. Typical failure symptoms include a clicking sound with no burner ignition, repeated ignition lockout fault codes, or intermittent no-heat operation.

• OEM Part Number: 48VL400002 | Superseded/replaced by Carrier P/N 50HJ403022 (also replaces 50HJ401430, 50HJ400608) — same factory-spec fit and function
• OEM vs Generic: This is a genuine Factory Authorized Carrier part, manufactured to exact OEM electrode gap, insulator material, and wire harness specifications. Aftermarket igniters can have inconsistent spark gap tolerances that lead to nuisance lockouts and premature failure.
• Install Difficulty: 3/5 — Disconnect power and shut off gas before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, and a multimeter to verify continuity. Handle the electrode ceramic insulator carefully — do not touch with bare hands. Photograph all wire routing before disconnecting.
• Warranty: 1-year OEM factory warranty against manufacturing defects. In-stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PY4GNAB30060AA packaged gas/electric unit. Verify your unit's model and data plate before ordering. Note that 48VL400002 has been superseded by Carrier P/N 50HJ403022 — both part numbers reference the same current OEM replacement. Questions about fitment?
