OEM Carrier Gas Furnace Flame Sensor Rod for PG9MAA060080ACKA

The flame sensor is a single metal rod that sits in the burner flame and confirms to the control board that the burners actually lit. It works by flame rectification — the lit burner conducts a tiny microamp DC current through the rod, telling the board to keep the gas valve open. If the board doesn't sense that current within a few seconds of ignition, it shuts the gas off for safety. When the sensor gets coated in oxide or carbon, that signal drops and you get the hallmark symptom: the furnace lights normally, burns for 3 to 7 seconds, then shuts off and tries again — short-cycling that repeats until the unit locks out. Weak heat, frequent lockouts, and a furnace that runs fine after cleaning but quits weeks later all point to the flame sensor. This OEM flame sensor uses a high-temperature Kanthal-type rod and the correct ceramic insulator and mounting position for the PG9MAA burner assembly, so it reads a strong, stable microamp signal (typically 2–6 µA) right where the board expects it. It ships with the matching gasket for a sealed, drop-in fit. OEM positioning matters: the rod length and bend place the tip in the optimal part of the flame. Generic sensors that sit too shallow or at the wrong angle read a weak signal that drifts below the board's threshold as the rod ages, returning you to nuisance short-cycling far sooner. Install difficulty: 1/5. Tools needed: 1/4" nut driver and fine emery cloth to clean adjacent surfaces. SAFETY: Turn off the gas and power at the unit before removing the sensor.
