OEM Carrier Gas Furnace Flame Sensor for PG8MAA066110ADJA

The flame sensor in your Carrier PG8MAA066110ADJA is a single metal rod that proves a flame is actually present after the burners light. Using flame rectification, it passes a tiny electrical current through the flame; if the control board doesn't see that current, it closes the gas valve within seconds as a safety measure. A dirty or failing sensor is the classic cause of short-cycling: the furnace lights normally, runs for 3 to 7 seconds, then shuts off and tries again — over and over — leaving the house cold despite a furnace that 'almost' works. The sensor is a Kanthal or stainless rod whose performance is measured as microamp (µA) flame current with a meter set to DC microamps in series. A healthy circuit typically reads several microamps; once a carbon/oxide film builds on the rod, current drops below the board's minimum threshold and it drops out. Rod length and mounting position must match OEM so the tip sits correctly in the flame. OEM matters because a sensor with the wrong rod geometry sits too high or low in the burner flame and misreads the flame current, recreating the same short-cycling you're trying to fix. Genuine Carrier rods use the correct alloy and length for a stable, repeatable signal. Install difficulty: 1 of 5. Tools: 1/4 in. nut driver, plus fine steel wool or emery cloth to gently clean the rod (often this alone restores it). #1 safety warning: turn off the gas supply and the power at the breaker before removing the sensor.
