OEM Carrier Gas Furnace Flame Sensor Rod for PG9MAA036060AAKA

The flame sensor is a single metal rod that sits directly in the burner flame and confirms to the control board that the gas actually lit. It works by flame rectification — the flame conducts a tiny DC current that tells the board 'flame present, keep the gas valve open.' When the rod becomes coated with oxide or carbon (the most common cause) or cracks, the board no longer senses flame and shuts the gas valve within seconds for safety. The tell-tale symptom on your Carrier PG9MAA036060AAKA: the burners light, you feel heat start, and then the furnace shuts off after 3–7 seconds and tries again — repeated short-cycling that ends in a lockout and no heat. This genuine OEM flame sensor uses the correct rod length, bend, and ceramic insulator so the tip sits in the proper part of the flame. A healthy sensor produces a microamp signal — typically around 2–6 µA DC — measured in series with a meter; below roughly 1 µA the board will drop out. Why OEM matters: a generic rod that's the wrong length or angle sits outside the flame envelope or too close to ground, producing a weak microamp signal and the same nuisance lockouts you're trying to fix. Correct geometry and a clean ground are everything with this part. Install difficulty: 1 of 5. Tools: 1/4" nut driver and fine emery cloth (to clean the rod if you're testing first). #1 safety warning: turn off the gas supply and kill power at the furnace disconnect before removing the sensor, and never sand a new rod — handle it by the insulator only.
