OEM Carrier Flame Sensor for PG95SAS48080BBAA 95% Gas Furnace

The flame sensor is a single metal rod that sits in the burner flame and proves the furnace actually ignited. It works by flame rectification — the lit flame conducts a tiny DC microamp current back to the control board, which tells the board it's safe to keep the gas valve open. When the rod oxidizes or fails, the most recognizable symptom is short-cycling: the burners light, run for 3 to 7 seconds, then shut off, repeat several times, and finally lock out with a flame-sense fault code. Homeowners notice the furnace 'trying' to heat but never staying on. This is a stainless-steel sense rod on a porcelain insulator, positioned and length-matched to Carrier's burner assembly so the rod sits fully immersed in flame. A healthy signal on this control reads roughly 1 to 6 microamps; anything drifting toward the board's minimum (around 0.5 µA) triggers lockout. The OEM rod holds the correct geometry and insulator rating for a clean, stable signal. OEM matters because flame-sense current depends entirely on rod length, alloy, and flame immersion. Generic sensors with the wrong bend or shorter rod sit at the edge of the flame, producing a weak signal that nuisance-trips even when the furnace is otherwise healthy — leading to repeat no-heat calls. Install difficulty: 1 of 5. Tools: 1/4" nut driver, fine emery cloth or steel wool to clean the rod, and a meter capable of reading DC microamps to verify. #1 safety warning: kill the 120V power at the breaker before removing the rod so the control board can't energize the igniter while you work.
