OEM Carrier Flame Sensor for PG95XAT42060BAAA Gas Furnace Repair

The flame sensor is a single metal rod that tells your Carrier Performance 95 furnace whether a flame is actually present after the igniter fires. Through flame rectification it passes a small microamp current through the burner flame to the control board; if that current isn't detected within a few seconds, the board treats it as a no-flame condition and shuts the gas valve for safety. As the rod gets dirty, corroded, or fatigued, the telltale symptom is short-cycling — the burners light, hold for only 3 to 7 seconds, then drop out, repeating until the furnace locks out and the house goes cold. The control board will usually flash a flame-sense or 'flame not detected' fault code while this happens. This OEM sensor uses a Kanthal/stainless sensing rod with a high-temperature ceramic insulator built to sit in the flame continuously. A good installed rod reads roughly 1 to 6 microamps DC; once the signal sags below about 0.5 µA it needs cleaning or replacement. The bracket geometry and rod length are matched to the Carrier burner so the tip lands in the correct part of the flame. Why OEM matters here: cheap aftermarket rods are commonly made from inferior alloys that oxidize and glaze quickly, dragging the microamp signal down and triggering repeat lockouts within weeks. A properly alloyed OEM rod keeps a steady, reliable signal for years. Install difficulty: 2 of 5. Tools: 1/4" nut driver, fine emery cloth or steel wool, and a multimeter capable of microamp readings. #1 safety warning: turn off the gas and cut power at the furnace switch or breaker before removing the sensor, and avoid bending the delicate rod.
