OEM Carrier Spark Electrode Ignitor Assembly 48GS400168 for Model PY3PPA060090NB

This is the OEM factory-specified spark electrode ignitor assembly (part number 48GS400168) for the Carrier PY3PPA060090NB packaged gas unit. The ignitor is responsible for initiating combustion each time your system calls for heat. When it fails, the control board will attempt ignition, detect no flame, and trigger a safety lockout — leaving you with a system that runs the inducer but produces no heat. Replacing this ignitor with the correct OEM part restores reliable ignition and prevents nuisance lockouts caused by weak or inconsistent spark.

• Specs: 2-rod spark electrode assembly | OEM part number 48GS400168 | Factory-matched geometry and gap spacing for Carrier 48GS-series gas pack platforms
• OEM vs Generic: OEM electrodes maintain the precise rod spacing and ceramic insulator rating required for consistent arc. Generic igniters often feature looser tolerances that result in intermittent ignition, repeat lockouts, and shortened service life.
• Install Difficulty: 2/5 — Shut off gas supply and disconnect power before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Photograph existing electrode wiring before disconnecting. Reconnect high-voltage ignition cable securely to avoid arcing to chassis.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
