OEM Carrier Spark Electrode Ignitor 48VL400002 for Model PY4GNAB24060NA

This is the genuine OEM factory-specified spark electrode ignitor for the Carrier PY4GNAB24060NA packaged gas/electric unit. The spark electrode ignitor generates the high-voltage arc that ignites the gas burner on each heating call. When this component fails or becomes fouled, the control board will attempt ignition, fail to detect a flame, and lock out the unit — leaving you with a no-heat fault code and a cold building. Replacing the ignitor with the correct OEM part restores factory ignition performance and prevents nuisance lockouts.

• Part Number: 48VL400002 (Superseded by Carrier P/N 50HJ403022 — same OEM fit and function) | Spark electrode ignitor assembly | Factory-matched ignition gap and ceramic insulator rating
• OEM vs Generic: Genuine Carrier OEM igniters are manufactured to exact gap tolerances and ceramic insulation ratings. Aftermarket spark electrodes frequently have inconsistent gap geometry, leading to weak arcs, misfires, and premature cracking of the ceramic body.
• Install Difficulty: 2/5 — Shut off gas supply and disconnect power at the disconnect box before beginning. Tools needed: 1/4" and 5/16" nut driver, needle-nose pliers. Photograph the electrode orientation and wiring connections before removal. Avoid touching the ceramic insulator with bare hands — skin oils can cause cracking under heat.
• Warranty: 1-year OEM factory warranty against manufacturing defects. In-stock and ships the same business day from our warehouse.

Compatibility: Designed as a direct OEM replacement for the Carrier PY4GNAB24060NA packaged unit. Note that OEM part 48VL400002 has been superseded by Carrier P/N 50HJ403022 — both are genuine Carrier parts and either number will fulfill this listing. Verify your unit's model and serial number on the data plate before ordering. Our fitment team is available to confirm compatibility before you buy.
