OEM Carrier Spark Electrode Ignitor Assembly 48GS400168 for Model PY1PPB060090AAAA

This is the genuine OEM spark electrode ignitor assembly (part #48GS400168) factory-specified for the Carrier PY1PPB060090AAAA Performance Series single-packaged gas heating/electric cooling rooftop unit. The ignitor assembly initiates combustion in the heat exchanger by generating a high-voltage spark across the electrode gap at the start of each heating cycle. When it fails, the control board will attempt ignition, find no flame, and lock the unit out — leaving you with a system that runs the inducer and clicks but never produces heat. A cracked ceramic insulator, corroded electrode tip, or broken mounting bracket are all common failure modes that require a full ignitor assembly replacement.

• OEM Part Number: 48GS400168 | Manufacturer Description: Spark Electrode Ignitor Assembly | 2-Rod configuration | Factory-matched geometry ensures correct spark gap for reliable light-off
• OEM vs Generic: This OEM assembly uses factory-spec ceramic insulators and electrode alloy. Generic alternatives can present inconsistent spark gap tolerances and inferior ceramic that cracks prematurely under repeated thermal cycling — risking recurring no-heat lockouts.
• Install Difficulty: 2/5 — Shut off gas supply and 24V control power before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Disconnect high-voltage ignitor cable carefully; inspect cable and boot for cracks while the unit is open. Photograph wire routing before removal.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before cutoff.
