OEM Carrier Spark Electrode Igniter 48GS400168 for Model PY1PJB048115NBAA

This is the factory OEM spark electrode igniter assembly (part #48GS400168) for the Carrier PY1PJB048115NBAA packaged gas/electric unit. The spark electrode igniter is responsible for initiating combustion in the heat exchanger each time a heating cycle begins. When the igniter fails, the control board will attempt ignition, detect no flame confirmation, and lock out the system — leaving you with a unit that runs the inducer but delivers no heat. Common symptoms include repeated ignition attempts followed by a lockout fault code, visible cracking or carbon tracking on the electrode tip, or a burner that sparks but fails to sustain flame.

• OEM vs Generic: This OEM igniter is manufactured to Carrier's exact electrode gap, ceramic insulator rating, and bracket geometry. Aftermarket igniters frequently ship with incorrect electrode spacing, leading to weak spark, nuisance lockouts, and premature failure.
• 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. Photograph wire harness routing before disconnecting. Ceramic insulators are fragile — handle with care and avoid touching the electrode tips.
