OEM Carrier Furnace Flame Sensor Rod for Model PY2PPB060090AB

The flame sensor is a single metal rod that confirms a flame is actually present after the burners light in your Carrier PY2PPB060090AB. It works by flame rectification: the lit flame conducts a tiny microamp current to ground, telling the control board it is safe to keep the gas valve open. When the rod is coated in oxide or has failed, the board can't 'see' the flame and shuts the gas off within 2–7 seconds as a safety measure. The textbook symptom is a furnace that lights, runs briefly, then dies — repeating over and over (short-cycling) before locking out and blowing cold air from the vents. Specs: This is a single-rod flame sensor with a ceramic insulator and a spade or screw terminal. A healthy circuit produces roughly 1–6 microamps of DC current, measured in series with a meter set to µA. A cracked porcelain insulator or a rod that won't hold signal after cleaning must be replaced. The rod length and bend position match OEM so it sits correctly in the flame envelope. OEM matters because the rod alloy, length, and mounting position determine how much surface area sits in the flame. Generic rods are often the wrong length or shape, producing a weak microamp signal that triggers nuisance lockouts even when the burners are firing perfectly. Install difficulty: 1/5. Tools: 1/4" nut driver, fine emery cloth or a Scotch-Brite pad (never sandpaper), and a multimeter that reads microamps. Safety: shut off the gas supply and power at the furnace switch before removing the rod. Ships same business day from our stocked warehouse on orders placed before 3 PM CST.
