OEM Carrier Spark Electrode Ignitor Assembly 48GS400168 for Model PY1PEB060090AAAA

This is the genuine OEM spark electrode ignitor assembly (part #48GS400168) factory-specified for the Carrier PY1PEB060090AAAA packaged gas unit. The ignitor's dual-rod electrode generates the high-voltage spark that lights the burner at the start of every heat cycle. When it fails, the control board will attempt ignition, detect no flame, and lock out — leaving you with a system that appears to run but produces no heat. Common symptoms include repeated ignition attempts followed by a red fault light or error code, or a furnace that clicks but never lights.

• Part Number: 48GS400168 | Carrier OEM Ignitor/Electrode Assembly | 2-Rod Configuration | Factory-matched spark gap and ceramic insulator
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part, manufactured to exact gap, material, and voltage specifications. Aftermarket igniters frequently use inferior ceramic insulators that crack under thermal stress, causing intermittent or permanent re-failure within one season.
• Install Difficulty: 2/5 — Straightforward swap accessible from the burner compartment. Tools needed: 1/4" nut driver, needle-nose pliers. Always shut off gas supply and 24V control power before servicing. Handle the ceramic electrode body carefully — do not touch the electrode tips or apply lateral pressure.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Direct OEM replacement for Carrier PY1PEB060090AAAA packaged gas units.
