OEM Carrier Gas Furnace Flame Sensor Rod for PG9MAA024060AAKA

The flame sensor is a single metal rod that sits in the burner flame and confirms to the control board that the burners actually lit. It works by flame rectification — a tiny microamp current passes from the rod through the flame to ground. When the rod oxidizes, carbons up, or cracks, the board can no longer "see" the flame and closes the gas valve within seconds as a safety measure. Homeowner symptoms: the furnace lights for 3–7 seconds then shuts off (short-cycling), repeated ignition retries, no heat, or a hard lockout error code after several failed tries. Specs: This is a single-rod stainless/ceramic sensor with an insulated 1/4" quick-connect terminal, built to match the PG9MAA burner geometry and mounting bracket. A healthy sensor reads a flame current of roughly 1–6 microamps DC when measured in series with a multimeter; once the signal drops below about 0.5 µA, the board drops out and locks the furnace. Why OEM: A flame rod must place its sensing tip at the exact depth and angle inside the flame envelope. Generic rods are often slightly different in length or bend, which lowers the microamp reading and causes intermittent lockouts even on an otherwise healthy furnace. OEM stainless alloy also resists oxidation far longer than the cheaper steel used in aftermarket rods. Install difficulty: 1/5. Tools: 1/4" nut driver, fine emery cloth or steel wool to clean the rod (never coarse sandpaper), and a multimeter to verify microamps. #1 safety warning: turn off the gas at the furnace shutoff valve and kill the breaker before reaching near the burners.
