OEM Carrier Gas Furnace Flame Sensor Rod for PG8MAA066110ACJA

The flame sensor is a single metal rod that sits in the burner flame and proves to the control board that the burners actually lit. It works by flame rectification — the lit flame conducts a tiny DC microamp current from the rod to ground, and the board reads that current as proof of flame. When the rod oxidizes or the signal weakens, the most common symptom appears: the furnace lights for 3 to 7 seconds, then the burners snap off and the inducer keeps running. After a few retries the board locks out, and you get no heat with a flame-sense fault code. Homeowners typically notice warm air that quits almost immediately and repeated short-cycling. Specs: this is a silicon-carbide-coated stainless/Kanthal sensing rod with a ceramic insulator and a single push-on terminal. A healthy flame signal on this furnace family is roughly 1.5 to 5.0 microamps DC; below about 1.0 microamp the board will drop out. The rod position and insulator length are model-specific so the tip lands correctly in the flame envelope. Generic rods often use thinner base metal and lower-grade insulators that oxidize faster and crack, shortening service life and producing erratic microamp readings. The OEM rod restores a clean, stable signal the board can trust. Install difficulty: 1 of 5. Tools needed: 1/4" nut driver, fine emery cloth or steel wool (to clean the new rod's mounting boss), and a multimeter set to DC microamps to verify signal. #1 safety warning: turn off the furnace gas shutoff and kill the breaker before reaching into the burner compartment.
