OEM Carrier Flame Sensor Replacement for Carrier PY1RPA150224ADWA

The flame sensor is a thin metal rod that sits directly in the burner flame and confirms to the control board that gas has actually ignited. It works by flame rectification — a tiny microamp current passes through the live flame to ground. When the rod becomes coated with oxide and carbon, or simply wears out, the board can no longer "see" the flame and shuts the gas valve within seconds as a safety measure. On your Carrier PY1RPA150224ADWA the classic symptom is a furnace that lights and then shuts off after roughly 3–7 seconds, repeats the ignition cycle several times, produces little or no heat, and finally goes into lockout requiring a reset. Genuine OEM flame sensors use a properly-alloyed stainless/Kanthal rod cut to the correct length and held in the factory bracket so it sits at the right depth in the flame. A healthy sensor passes a flame-rectification signal of roughly 2–6 DC microamps measured in series; once the signal drops below about 0.5 µA the board drops out and closes the gas valve. Why OEM matters: generic rods are often thinner or made from a different alloy that oxidizes far faster and frequently mounts at the wrong depth, producing a weak signal that causes nuisance lockouts within a few months. The correct OEM geometry keeps the microamp signal strong and stable for years. Install difficulty: 1 of 5. Tools needed: 1/4" nut driver, fine steel wool or emery cloth, and a multimeter capable of reading DC microamps. #1 safety warning: shut off the gas supply and kill power at the furnace switch/breaker before servicing.
