OEM Carrier Flame Sensor for PG8JAA060155ADJA Gas Furnace

The flame sensor is a single metal rod that sits in the burner flame and confirms to the control board that the gas is actually lit. It works by flame rectification — the lit flame conducts a tiny microamp DC current that tells the board to keep the gas valve open. On your Carrier PG8JAA060155ADJA, when this rod gets coated with oxide or carbon, that current drops and the board can no longer prove flame. The classic symptom: the burners light for 2–5 seconds, then the gas valve snaps shut and the furnace short-cycles, often locking out after three or four tries with no heat to the house. This is a porcelain-insulated sensing rod with a single spade terminal. A healthy sensor reads a flame-current signal in the 1–6 microamp range (measured in microamps DC in series with the sensor wire); anything under ~0.5 µA will cause dropout. The rod is stainless and should be mounted so it's fully engulfed by the flame. Why OEM matters: the rod length, bend angle, and insulator are sized to sit correctly in this furnace's burner. A generic flame sensor that's the wrong length or angle won't see enough flame to generate reliable current, giving you intermittent lockouts even when it's brand new. The OEM rod positions exactly like the original and its insulator is rated for repeated thermal cycling without cracking. Install difficulty: 1/5 — one of the easiest furnace repairs. Tools: 1/4" nut driver or 5/16" socket, light sandpaper or a Scotch-Brite pad. #1 safety warning: TURN OFF THE GAS and kill power at the breaker before pulling the sensor — you're working right at the burner assembly.
