OEM Carrier Spark Electrode Ignitor Assembly (48GS400168) for Model PY2PEB036090AA

This is the genuine OEM spark electrode ignitor assembly for the Carrier PY2PEB036090AA packaged gas/electric unit. The ignitor assembly generates the high-voltage spark needed to ignite the gas burner at the start of every heat cycle. When the ignitor fails, the unit will attempt ignition, fail to light the burner, and enter a safety lockout — leaving you with no heat and a blinking fault code on the control board. Replacing this part with the correct OEM assembly restores reliable ignition and prevents repeat service calls.

Disconnect the high-voltage ignitor cable, remove the mounting screws, swap the assembly, and confirm electrode gap alignment before reassembly. Always verify ignition operation through a full call-for-heat cycle.
