OEM Carrier Spark Electrode Ignitor Assembly 48GS400168 for Model PY2PEB048115AA

This is the genuine OEM Carrier spark electrode ignitor assembly, factory part number 48GS400168, engineered as the direct replacement for the Carrier PY2PEB048115AA packaged gas/electric unit. The spark electrode ignitor generates the high-voltage spark needed to ignite the gas burner on each call for heat. When this component fails, the control board will attempt ignition, detect no flame, and lock out the system — leaving you with no heat and a blinking fault code. Common failure symptoms include repeated ignition lockouts, a spark that fires but fails to light the burner, a cracked or fouled electrode tip, or a broken ignition wire lead.

• OEM Part Number: 48GS400168 | Replaces PSE-CE15 | Factory-authorized Carrier replacement component
• OEM vs. Generic: This genuine Carrier OEM assembly is manufactured to exact factory electrode gap and ceramic insulator specifications. Aftermarket igniters often suffer from inconsistent spark gap tolerances, leading to unreliable ignition and premature failure — especially in packaged rooftop environments subject to vibration and temperature extremes.
• Install Difficulty: 2/5 — Straightforward swap on most packaged units. Turn off gas supply and 24V power before servicing. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Photograph existing wire routing before disconnecting the ignition lead. Handle ceramic insulator carefully to avoid cracking.
• Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse.
