OEM Carrier Flame Sensor for PG8DAA048115ADJA Gas/Electric Unit

The flame sensor in your Carrier PG8DAA048115ADJA is a single metal rod seated directly in the burner flame. It confirms ignition through flame rectification — a tiny electrical current that proves a real flame is present so the control board keeps the gas valve open. When the rod becomes coated with carbon, oxidizes, or develops a hairline crack in its porcelain insulator, the board can no longer sense flame and closes the gas valve within seconds. Homeowners notice the burners lighting and then immediately going out, the blower pushing cold air, short-cycling, or a hard lockout with no heat after three or four failed ignition attempts. This is a stainless-steel/Kanthal sensing rod with a high-temperature porcelain insulator. A healthy sensor produces a microamp flame-rectification signal in the 1–5 µA range; once the reading drops below roughly 0.5 µA the board flags loss of flame. The rod length and bend are matched to this Carrier burner so the flame fully envelops the tip. Why OEM matters here: aftermarket rods are frequently the wrong length or use a lower-grade alloy, so the flame only partially contacts the tip. That yields a weak, drifting microamp signal and nuisance lockouts on cold mornings when the unit is working hardest. The OEM rod restores a strong, stable signal. Install difficulty: 2 of 5. Tools: 1/4" nut driver, fine steel wool or emery cloth to clean the mating surface, and a multimeter set to DC microamps to verify the signal. #1 safety warning: shut off the gas supply and kill power at the breaker before removing the sensor.
