OEM Carrier Spark Electrode Ignitor (48GS400168) for Model PY3PPA048130AA

This is the factory OEM spark electrode ignitor assembly for the Carrier PY3PPA048130AA packaged heating and cooling unit. The spark electrode ignitor is the critical first link in your system's heat sequence — it generates the high-voltage spark that ignites the burner on each call for heat. When this component fails or degrades, the control board will attempt ignition, detect no flame, and enter a safety lockout, leaving you with a system that powers on but delivers no heat. Common failure symptoms include the unit attempting to light 2–3 times before locking out, or intermittent no-heat complaints that reset after a power cycle.

• OEM Part Number: 48GS400168 | Manufacturer Description: Spark Electrode Ignitor Assembly | Replaces legacy part PSE-CE15
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part, manufactured to exact electrode gap and ceramic insulator specifications. Off-brand electrodes frequently suffer from inconsistent gap tolerances, leading to unreliable spark arc and repeat lockouts — especially in high-cycle commercial applications.
• Install Difficulty: 2/5 — Straightforward electrode swap. Shut off gas and power at the disconnect before beginning. Tools needed: 1/4" nut driver, needle-nose pliers. Handle the ceramic insulator carefully — avoid dropping or side-loading. Photograph wire routing and electrode positioning before removal.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
