OEM Carrier Spark Electrode Ignitor 48VL400002 for Model PY4GEAB42060NA

This OEM spark electrode ignitor is the factory-specified replacement for the Carrier PY4GEAB42060NA packaged gas/electric unit. The spark electrode ignitor generates the high-voltage arc that lights the main gas burner on each call for heat. When this component fails, the unit will typically attempt ignition, fail to establish flame, and enter a hard lockout — leaving your system with no heat and a fault code on the control board. Replacing the ignitor with a genuine OEM part restores reliable ignition and prevents nuisance lockouts caused by a weak or broken electrode.

• Part Number: 48VL400002 (OEM Carrier / Factory Authorized Parts) | Also superseded by Carrier P/N 50HJ403022 — confirm fitment with your unit's data plate before ordering.
• OEM vs Generic: OEM spark electrodes are manufactured to exact factory gap and ceramic insulator specifications. Off-brand electrodes frequently have inconsistent spark gap tolerances, leading to unreliable ignition, nuisance lockouts, and premature control board stress.
• Install Difficulty: 2/5 — Shut off gas supply and disconnect power at the disconnect switch before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, and a phone or camera to photograph wiring harness routing before removal. The electrode mounts to the burner assembly with 1–2 screws; handle the ceramic insulator carefully to avoid cracking.
• Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse in original Carrier factory packaging.

Compatibility: Designed for the Carrier PY4GEAB42060NA packaged unit. Note that OEM part 48VL400002 has been superseded by Carrier P/N 50HJ403022 — both are genuine Carrier parts covering the same application. Always verify the part number against your unit's wiring diagram and data plate. Have questions about fitment?
