OEM Carrier Flame Sensor 50HJ401431 for Model PY1REA150224ADWB

This is the factory OEM replacement flame sensor for the Carrier PY1REA150224ADWB packaged unit. The flame sensor (also called a flame rod) is a safety component mounted in the burner assembly that detects the presence of a live flame by passing a small microamp current through the flame and back to the control board. When the sensor becomes coated with oxidation or carbon buildup — or fails entirely — the control board cannot confirm ignition and shuts off the gas valve as a safety measure. The result: your furnace or packaged unit lights, runs for 5 to 8 seconds, then shuts down, often repeating the cycle until it locks out.
