OEM Carrier Spark Electrode Igniter (48GS400168) for Model PY1PJB048090ABAA

This is the OEM factory-specified Spark Electrode Igniter Assembly (Part# 48GS400168) for the Carrier PY1PJB048090ABAA packaged gas/electric unit. The igniter is the first critical component in every heating cycle — it generates the high-voltage spark that ignites the gas burners. When the igniter fails or degrades, the control board will attempt ignition, detect no flame, and lock out the system, leaving you with a no-heat call and a flashing fault code.

• Specs: 2-rod spark electrode igniter assembly | Factory Authorized Parts (FAP) | OEM direct replacement for Carrier 48GS gas pack units | Exact fit — no modification required
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part, engineered to exact electrode gap and ceramic insulator specifications. Generic igniters may use off-spec gap tolerances that result in weak or intermittent spark, causing nuisance lockouts and repeat service calls.
• Install Difficulty: 2/5 — Shut off gas and 24V control power before servicing. Tools needed: 1/4" nut driver, needle-nose pliers. Disconnect the igniter harness, remove the mounting screw, swap the electrode assembly, and re-verify gap before restoring power. Always test for ignition on the first call for heat.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
