OEM Carrier Spark Electrode Ignitor Assembly 48GS400168 for Model PY1PPB048115NBAA

This is the genuine OEM spark electrode ignitor assembly (part #48GS400168) factory-specified for the Carrier PY1PPB048115NBAA packaged gas/electric unit. The ignitor is the first component in the heating sequence — it generates the spark or surface heat required to light the burner. When it fails, the control board will attempt ignition, fail to sense flame, and lock out the system, resulting in a no-heat call. Common symptoms include the inducer running normally but the burners never firing, or repeated ignition lockout fault codes on the board.

• Part Number: 48GS400168 | OEM Carrier Spark Electrode Ignitor Assembly | Factory-direct replacement, no modifications required
• OEM vs Generic: OEM igniters are manufactured to exact gap tolerance and ceramic insulator specifications. Generic igniters frequently have inconsistent electrode gaps and lower-grade ceramics, leading to nuisance lockouts and premature failure — especially in packaged rooftop applications subject to vibration and weather exposure.
• Install Difficulty: 2/5 — Straightforward swap requiring a nut driver and needle-nose pliers. Always disconnect power at the disconnect and confirm zero voltage before handling. Photograph all wire connections and harness routing before removal. Handle the ceramic ignitor body carefully — do not touch the electrode tip with bare hands, as oils from skin can cause premature cracking under heat.
• Warranty: 1-year OEM factory warranty. In-stock orders ship the same business day from our warehouse.
