OEM Carrier Spark Electrode Igniter 48GS400168 for Model PY3PEA048115AB

This is the factory-authorized OEM spark electrode igniter assembly (part# 48GS400168) for the Carrier PY3PEA048115AB packaged gas/electric unit. The spark electrode igniter is responsible for initiating combustion each time the system calls for heat. When it fails, the control board will attempt ignition, detect no flame, and lock out the system — leaving you with a blinking fault code and no heat. Replacing this igniter with the correct OEM part restores reliable, factory-spec ignition performance.

• Part Type & Specs: Spark electrode igniter assembly (2-rod configuration) | Direct OEM replacement | Factory-matched fit and geometry for precise spark gap alignment
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part — not an aftermarket substitute. OEM electrodes maintain exact rod spacing and ceramic insulator specs, reducing the risk of misfires, premature wear, or nuisance lockouts common with off-brand alternatives.
• Install Difficulty: 2/5 — Shut off gas and power before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Photograph existing wiring and electrode orientation before removal. Reconnect leads securely to prevent arcing.
