OEM Carrier Spark Electrode Ignitor 48GS400168 for Model PY3PNA024060AB

This is the genuine OEM Carrier spark electrode ignitor (Part# 48GS400168), factory-specified for the Carrier PY3PNA024060AB packaged unit. The spark electrode ignitor initiates combustion by generating a high-voltage spark across the electrode gap at the burner assembly. When this component fails, the control board will attempt ignition — typically one to three times — before entering a hard lockout, leaving the unit with no heat output. Common failure symptoms include a no-heat call with a visible ignition-attempt LED fault code, repeated clicking with no flame establishment, or a visibly cracked, fouled, or eroded electrode tip.

• Part Specs: Spark electrode ignitor assembly | OEM Part# 48GS400168 | Replaces PSE-CE15 | Factory-matched electrode gap and ceramic insulator geometry for reliable arc initiation
• OEM vs Generic: The OEM assembly ensures exact electrode geometry, ceramic insulator grade, and terminal connector fit — eliminating the misfires and nuisance lockouts often caused by aftermarket electrodes with imprecise gap tolerances.
• Install Difficulty: 2/5 — Shut off gas supply and 24V control power before servicing. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Note ignition wire routing before removal; do not handle the ceramic insulator with bare hands — skin oils can cause cracking under heat.
• Warranty: 1-year OEM manufacturer warranty. In-stock and ships same business day from our warehouse.
