OEM Carrier Spark Electrode Ignitor 48GS400168 for Model PY3PEA048115NA

This is the genuine OEM Carrier spark electrode ignitor assembly (part number 48GS400168), the factory-specified replacement for the Carrier PY3PEA048115NA packaged unit. The spark electrode ignitor is responsible for initiating combustion each time your unit calls for heat. When this component fails, the control board will attempt ignition, detect no flame, and lock out the system — leaving you with no heat and a fault code. Common failure symptoms include repeated ignition lockouts, a visible crack or carbon tracking on the electrode tip, or intermittent no-heat calls that reset after a power cycle.

• OEM Part Number: 48GS400168 | Factory-authorized Carrier replacement | Replaces PSE-CE15
• OEM vs Generic: This genuine Carrier OEM ignitor is manufactured to exact factory gap spacing and ceramic insulator specifications. Off-brand electrodes can exhibit inconsistent spark gap tolerances, leading to unreliable ignition or premature ceramic cracking under thermal cycling.
• Install Difficulty: 2/5 — Shut off gas supply and disconnect power before servicing. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Photograph wiring harness connector orientation before disconnecting. Handle ceramic insulator carefully — do not apply lateral stress to the electrode tip.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before cutoff.
