OEM Carrier Spark Electrode Ignitor Assembly 50HJ403022 for Model PY1REA048074AAWA

This is the genuine OEM spark electrode ignitor assembly for the Carrier PY1REA048074AAWA packaged gas/electric unit. The ignitor assembly generates the high-voltage spark that ignites the gas burner at the start of every heat cycle. When this component fails, the control board will attempt ignition, detect no flame, and trigger a hard lockout — leaving the system completely unable to produce heat. Common failure symptoms include a furnace that attempts to fire but shuts down within seconds, a blinking fault code indicating ignition failure, or a visibly cracked or fouled electrode tip.
