OEM Carrier Furnace Flame Sensor Rod for PG8MAA036110ADJA Unit

The flame sensor is a single metal rod that sits directly in the burner flame and confirms — through flame rectification — that the burners actually lit after the igniter fired. The control board reads a tiny microamp current passing through the flame. When the rod oxidizes or its porcelain insulator cracks, the board can no longer 'see' the flame and shuts the gas valve within seconds as a safety. The classic symptom is burners that light for 3-7 seconds and then go out, with the furnace short-cycling — light, drop, retry, lockout — leaving the home with little or no heat. Specs: This is a flame-rectification rod, not a thermocouple. A clean sensor in a healthy flame should pass roughly 1-6 microamps DC (measured in series with a meter set to µA); below about 0.5-1 µA the board will drop the flame and close the gas valve. The rod mounts with a single screw and carries a low-voltage signal lead back to the control board. OEM vs Generic: Although inexpensive, a flame sensor must have the correct rod length, alloy, and porcelain insulator so it sits properly in the flame and resists oxidation. Generic rods built with thinner wire or poorly fired ceramic foul and crack faster, returning you to short-cycling within a single season. OEM geometry guarantees correct flame immersion and a stable microamp signal. Install: Difficulty 1/5. Tools: 1/4" nut driver or 5/16" socket, plus fine emery cloth or steel wool if inspecting the old rod. Safety: turn off the gas and the furnace breaker before removing the sensor from the burner assembly. Ships same business day from our stocked warehouse on orders placed before 3 PM CST.
