OEM Carrier Flame Sensor 50HJ401431 for Model PY1RPA036074ABWB

This is the genuine OEM Carrier flame sensor (part #50HJ401431) factory-specified for the Carrier PY1RPA036074ABWB packaged gas heating unit. The flame sensor — also called a flame rod — is a critical safety component mounted in the burner assembly. It passes a small microamp current through the flame to confirm combustion is present. When the sensor fails or its probe becomes coated with oxidation, the control board cannot verify a flame, triggering a safety lockout. The most common symptom: the burner ignites normally, runs for 5–8 seconds, then shuts off and the system goes into lockout — repeatedly.
