OEM Carrier Furnace Flame Sensor Replacement for PY3PEA060115AA

The flame sensor is a single metal rod that sits in the burner flame and confirms to the control board that the gas has actually ignited. It works by flame rectification — the lit flame conducts a tiny microamp current to ground, proving combustion. When the rod oxidizes or cracks, the board no longer sees that current and shuts the gas valve as a safety measure. The classic symptom is a furnace that lights for a few seconds and then shuts off, repeating in a short-cycle pattern: ignition, brief flame, shutdown, retry. After several failed tries the board often locks out, leaving you with no heat and sometimes a blinking error code on the control board. This genuine Carrier flame sensor uses the correct rod length, alloy, and ceramic insulator so it generates a stable flame-rectification signal in the microamp range the board expects (typically around 2-6 µA on a healthy flame). The mounting bracket and spade terminal match the original, so it seats at the proper depth in the flame envelope without bending. OEM matters because aftermarket sensors often use thinner or lower-grade rod material that oxidizes faster and produces a weaker, noisier signal. A marginal signal causes intermittent lockouts that are maddening to diagnose. The genuine part restores a clean, strong flame-sense reading and reliable ignition. Installation difficulty: 1/5. Tools needed: 1/4" nut driver, fine steel wool or emery cloth (to clean the area), and a multimeter set to microamps if you want to verify the signal. #1 safety warning: turn off the gas at the furnace shutoff valve and kill power at the furnace switch before removing the sensor.
