OEM Carrier Spark Electrode Ignitor Assembly (48GS400168) for Model PY3PEA060090AA

This is the genuine OEM spark electrode ignitor assembly, part number 48GS400168, factory-specified for the Carrier PY3PEA060090AA packaged gas unit. The ignitor assembly generates the high-voltage spark that ignites the gas burner on each heating call. When the ignitor fails, the furnace or packaged unit will attempt ignition, fail to light, and enter a safety lockout — leaving you with no heat. Common symptoms include the inducer running normally but the burners never lighting, a visible cracked or fouled electrode tip, or repeated ignition fault error codes on the control board.

• Part Specs: 2-rod spark electrode design | OEM part number 48GS400168 | Lightweight 0.07 lb assembly | Package dimensions: 3.80 × 1.40 × 4.90 in | Factory-matched geometry ensures correct spark gap
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part. OEM electrodes maintain the precise rod alignment and ceramic insulator quality required for reliable ignition. Aftermarket electrodes may have incorrect spark gap or inferior ceramics, leading to repeated ignition faults and premature failure.
• Install Difficulty: 2/5 — Turn off gas and power at the disconnect before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Photograph the existing electrode orientation and wire routing before removal. Handle the ceramic insulator carefully — do not drop or overtighten mounting screws.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.
