OEM Carrier Flame Sensor Rod for PY1PEB036090ABAA Gas Furnace

The flame sensor is the safety device that confirms your Carrier PY1PEB036090ABAA actually lit. Seconds after the gas valve opens, this metal rod sits in the burner flame and uses flame rectification to send a tiny microamp DC signal back to the control board, proving fire is present. When the rod oxidizes or carbons over, that signal drops and the board shuts the gas off to prevent unburned gas buildup. The homeowner symptom is unmistakable: the furnace lights for 3–5 seconds, then the flame goes out and the cycle repeats — short-cycling with no sustained heat, often ending in a lockout after several tries. This is an OEM flame sensor rod with the correct rod length, ceramic insulator, and mounting bracket for the PY1PEB burner assembly. A healthy sensor reads roughly 2–6 microamps DC in flame; below ~1 µA the board will drop out. A coated rod can sometimes be cleaned with fine steel wool, but a cracked insulator or pitted rod must be replaced. Why OEM matters: generic sensors often use a different rod alloy or length that sits wrong in the flame, producing a weak or unstable microamp signal and the same short-cycling you're trying to fix. A cracked aftermarket ceramic can short the rod to ground and kill ignition entirely. The OEM rod restores a clean, stable flame-rectification signal. Install difficulty: 1/5 — one of the easiest furnace repairs. Tools: 1/4" nut driver, fine steel wool, multimeter set to microamps DC. SAFETY: turn off the gas and the furnace breaker before pulling the sensor; route the new wire clear of the burner.
