OEM Carrier Flame Sensor for PG95XAT42060BBAA Gas Furnace Repair

The flame sensor is a single metal rod that confirms your Carrier Performance 95 furnace has actually established a flame after the igniter fires. Using flame rectification, it passes a tiny microamp current through the burner flame back to the control board; if no current is detected within a few seconds, the board assumes there is no flame and closes the gas valve as a safety measure. When the rod is dirty, corroded, or failing, the symptom homeowners notice most is short-cycling — the burners light, run for 3 to 7 seconds, then shut off, often repeating several times before the furnace locks out and leaves the house with no heat. You may also see the control board flashing a flame-sense fault code. This OEM sensor uses a Kanthal/stainless sensing rod and a high-temperature ceramic insulator rated for continuous exposure to the burner flame. A healthy installed sensor produces a flame-rectification signal of roughly 1 to 6 microamps DC; readings that drift below about 0.5 µA mean it is time to clean or replace the rod. The mounting flange and probe length are matched to the Carrier burner assembly so the rod sits correctly in the flame envelope. Why OEM matters here: aftermarket rods are often made from lower-grade alloys that oxidize and glaze over far faster, collapsing the microamp signal and causing nuisance lockouts within weeks. A correctly alloyed OEM rod holds a stable signal far longer. Install difficulty: 2 of 5. Tools: 1/4" nut driver, fine emery cloth or steel wool, and a multimeter that reads microamps. #1 safety warning: shut off the gas and kill power at the furnace switch or breaker before removing the sensor, and do not over-bend the rod.
