OEM Carrier Spark Electrode Ignitor Assembly 48GS400168 for Model PY1PPB048115AAAA

This OEM spark electrode ignitor assembly (part #48GS400168) is the factory-authorized replacement ignitor for the Carrier PY1PPB048115AAAA packaged gas/electric unit. The ignitor is responsible for igniting the gas burner during each heating cycle. When this component fails, the control board will attempt ignition, detect no flame, and trigger a safety lockout — leaving you with no heat. Common symptoms include the inducer motor running normally but the burner never lighting, repeated ignition attempts followed by a fault code, or a visibly cracked or corroded electrode tip.

• OEM Part Number: 48GS400168 | Manufacturer description: Spark Electrode Ignitor Assembly | Factory-authorized Carrier replacement
• OEM vs Generic: This is a genuine OEM assembly built to exact Carrier factory tolerances — including precise electrode gap, ceramic insulator grade, and lead wire length. Aftermarket igniters can have inconsistent electrode gaps and inferior ceramics that crack prematurely under thermal cycling, leading to repeat failures.
• Install Difficulty: 2/5 — A straightforward swap on the PY1PPB048115AAAA. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Always shut off gas supply and disconnect power before servicing. Handle the ceramic electrode body carefully — do not touch the tip with bare hands as skin oils can cause premature cracking.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before cutoff.
