OEM Carrier Spark Electrode Igniter Assembly 48GS400168 for Model PY1PPB036090AAAA

This OEM spark electrode igniter assembly (part #48GS400168) is the factory-specified replacement for the Carrier PY1PPB036090AAAA packaged gas/electric unit. The igniter is the first critical component in the gas ignition sequence — it generates the spark that lights the burner. When it fails, the control board will attempt ignition, detect no flame, and lock out the system, resulting in a no-heat call. Common symptoms include repeated ignition attempts with no burner light-off, a flashing fault code on the control board, or a furnace that runs the inducer but never produces heat.

• Part Number: 48GS400168 | OEM Carrier Ignitor/Electrode Assembly | 2-Rod Spark Electrode Design | Factory-matched geometry and gap specification
• OEM vs Generic: This is a genuine OEM Carrier igniter built to exact factory electrode gap and ceramic insulator specs. Generic igniters may use inferior ceramics prone to cracking or improper rod geometry, causing intermittent spark failure or premature failure under thermal cycling.
• Install Difficulty: 2/5 — Straightforward swap requiring a 1/4" nut driver and needle-nose pliers. Always disconnect power and shut off gas before servicing. Photograph existing electrode routing and wire connections before removal. Handle ceramic insulator carefully — do not drop or stress the assembly.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.
