OEM Carrier Gas Furnace Flame Sensor Rod for PG9MAB060120LBSA

The flame sensor is a single metal rod that sits directly in the burner flame and confirms to the control board that the gas has actually lit. It works by flame rectification: the lit flame conducts a tiny microamp current that tells the board it is safe to keep the gas valve open. On a Carrier PG9MAB furnace, a dirty or failed flame sensor is the single most common cause of a furnace that lights for a few seconds and then shuts off. You'll notice the burners ignite, run 3–7 seconds, then go out — often repeating several times before the board locks out and the house starts to cool. This OEM flame sensor uses the correct rod length, ceramic insulator, and mounting bracket so the tip lands in the proper part of the flame cone and reads a strong, stable microamp signal (typically 2–6 µA on a healthy system). The OEM ceramic resists cracking and shorting to ground far better than thin generic rods. Why OEM for a flame sensor: a generic rod with the wrong length or position reads a weak signal, so the board drops the gas valve early and you get the same nuisance short-cycling you were trying to fix. A cracked aftermarket insulator grounds out and triggers random lockouts. The OEM part restores a clean, repeatable signal the board can trust. Install difficulty: 1/5. Tools: 1/4" or 5/16" nut driver, plus fine emery cloth (never sandpaper) if you also clean adjacent components. SAFETY: turn off the gas at the manual shutoff valve and kill the furnace breaker before removing the sensor near the burners.
