OEM Carrier Flame Sensor Rod for Furnace Model PG8UAA048111ADJA

The flame sensor is the safety eye of your Carrier PG8UAA048111ADJA gas furnace. After the burners light, this single metal rod sits in the flame and uses flame rectification — passing a tiny microamp DC current through the ionized flame — to prove to the control board that a fire actually exists. When the sensor is dirty, oxidized, or failing, the furnace lights for a few seconds and then shuts the gas off, the classic short-cycle: ignite, run 3-7 seconds, drop out, retry, and eventually lock out with no heat. This genuine OEM Carrier flame rod uses the correct Kanthal alloy element and precise rod length/position so it sits properly in the burner flame. A healthy sensor reads roughly 1-6 microamps DC of flame current; readings below ~0.5 µA trigger flame-loss lockouts. OEM matters because aftermarket rods are often the wrong length or alloy, so they sit at the edge of the flame and generate marginal microamp signals that work cold but drop out once the furnace heats up — producing intermittent faults that mimic a bad board. A genuine rod delivers a strong, stable flame signal. Install difficulty: 1 of 5. Tools needed: 1/4" nut driver and fine steel wool or emery cloth (for the connector terminals, not the rod tip). SAFETY: turn off the gas at the furnace shutoff and kill the breaker before removing the sensor near the burner assembly. Never sand the sensor rod itself — replace it.
