OEM Carrier Furnace Flame Sensor Rod for Model PY2PPB060090AA

The flame sensor is a single metal rod that verifies a flame is present once the burners ignite in your Carrier PY2PPB060090AA furnace. It relies on flame rectification: the lit flame passes a tiny microamp current to ground, signaling the control board that it is safe to keep the gas valve open. When the rod becomes coated in oxide or fails outright, the board loses the flame signal and closes the gas valve within a few seconds for safety. The classic symptom is a furnace that fires up, runs for only a few seconds, then shuts down — cycling repeatedly before locking out and pushing cold air through the registers. Specs: This is a single-rod flame sensor with a ceramic insulator and a spade/screw terminal. A healthy flame circuit produces roughly 1–6 microamps of DC current, read in series with a meter set to µA. If the porcelain is cracked or the signal stays weak after cleaning, the rod must be replaced. The rod's length and bend match OEM so it seats properly in the flame. OEM matters because the alloy, length, and position of the rod control how much of it sits inside the flame. Generic rods are frequently the wrong shape or length, yielding a low microamp reading that causes nuisance lockouts even when combustion is normal. Install difficulty: 1/5. Tools: 1/4" nut driver, fine emery cloth or a Scotch-Brite pad (never sandpaper), and a multimeter capable of reading microamps. Safety: shut off the gas supply and cut power at the furnace switch before removing the sensor. Ships same business day from our stocked warehouse on orders placed before 3 PM CST.
