OEM Carrier Spark Electrode Ignitor Assembly 48GS400168 for Model PY1PEB042090AAAA

This is the genuine OEM spark electrode ignitor assembly (part number 48GS400168), factory-specified for the Carrier PY1PEB042090AAAA packaged gas/electric unit. The ignitor assembly generates the high-voltage spark that lights the burner at the start of every heating cycle. When this 2-rod electrode assembly fails or cracks, the control board cannot confirm ignition, triggering a safety lockout — typically resulting in a no-heat call with the system repeatedly cycling off without producing flame. Replacing this part is one of the most common furnace and packaged-unit repairs performed each heating season.
