OEM Carrier Spark Electrode Ignitor 48GS400168 for Model PY3PPA042060NA

This is the factory OEM spark electrode ignitor assembly (part# 48GS400168) designed as a direct replacement for the Carrier PY3PPA042060NA packaged unit. The spark electrode ignitor generates the high-voltage arc that lights the burner on every heating call. When this component fails or cracks, the control board will attempt ignition, detect no flame, and lock out — leaving you with a no-heat call and a blinking fault code. Replacing this ignitor with the genuine OEM assembly restores reliable ignition and avoids repeated nuisance lockouts.

• Specs: Spark electrode ignitor assembly | OEM part# 48GS400168 | Replaces PSE-CE15 | Factory-matched electrode gap and ceramic insulator rating | Includes electrode body and mounting hardware
• OEM vs Generic: The OEM ignitor is manufactured to exact Carrier electrode gap, ceramic grade, and wire termination specs. Generic electrodes frequently suffer premature ceramic cracking or mismatched gap spacing, leading to inconsistent spark and repeat lockouts.
• Install difficulty: 2/5 — Shut off gas and power before beginning. Tools needed: 1/4" nut driver, flat-head screwdriver, needle-nose pliers. Photograph the original wire routing before disconnecting. Ceramic electrode tips are fragile — handle with care and avoid contact with oils.
• Warranty: 1-year OEM factory warranty. Orders placed by 3 PM ship same business day from our warehouse.

Compatibility: Fits Carrier model PY3PPA042060NA packaged gas/electric unit. Also used across a wide range of Carrier package units that originally specified the PSE-CE15 spark electrode.
