OEM Carrier Spark Electrode Ignitor Assembly 48GS400168 for Model PY3PEA036090NA

This is the genuine OEM spark electrode ignitor assembly (part #48GS400168) factory-specified for the Carrier PY3PEA036090NA packaged gas/electric unit. The spark electrode ignitor is responsible for initiating combustion at the burner on each call 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 blinking fault code. Replacing the ignitor assembly with the correct OEM part restores reliable, factory-calibrated spark timing and gap geometry.
