OEM Carrier Spark Electrode Ignitor (48GS400168) for Model PY2PPB042090AB

This is the genuine OEM Carrier spark electrode ignitor assembly, part number 48GS400168, factory-specified for the Carrier PY2PPB042090AB packaged gas/electric unit. The spark electrode ignitor is a critical ignition component: when your system calls for heat, it generates the high-voltage spark that ignites the gas burner. When this part fails, the unit will attempt ignition, fail to light, and enter a safety lockout — leaving you with no heat. Common failure symptoms include repeated ignition attempts without flame establishment, a system that locks out after 3 tries, or visible cracking/carbon tracking on the electrode tip.
