OEM Carrier Spark Electrode Ignitor 48VL400002 for Model PY4GEAB48115AA

This OEM spark electrode ignitor (part number 48VL400002, superseded by 50HJ403022) is the factory-specified replacement for the Carrier PY4GEAB48115AA packaged gas/electric unit. The spark electrode ignitor generates the high-voltage arc that lights the burner on each call for heat. When it fails, the control board will attempt ignition, detect no flame, and lock out the system — leaving you with a unit that attempts to start but delivers no heat. Fault codes and repeated short-cycling are the most common symptoms of a failed ignitor on this platform.

• Specs: OEM Carrier spark electrode ignitor | Part No. 48VL400002 (current supersede: 50HJ403022) | Factory-matched electrode gap and bracket geometry | Designed for Carrier packaged rooftop/gas-electric applications
• OEM vs Generic: OEM igniters are precision-manufactured to exact electrode gap tolerances. Generic alternatives often use inconsistent gap spacing, leading to misfires, nuisance lockouts, and accelerated control board wear over time.
• Install difficulty: 2/5 — Always disconnect power and shut off gas before servicing. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, digital multimeter. Photograph existing electrode orientation and wire routing before removal. Handle the ceramic insulator carefully to avoid cracking.
