OEM Carrier Flame Sensor for PG8DAA036070ABJA Gas Pack Furnace

The flame sensor is the safety device that confirms your burners have ignited. It's a single rod positioned in the burner flame that relies on flame rectification — a small microamp current flowing through the flame back to the control board. When the rod oxidizes, cracks, or its ceramic insulator fails, the board loses the flame signal and shuts the gas valve within 2-4 seconds. On this PG8DAA036070ABJA packaged unit the classic symptom is short-cycling: the furnace ignites, runs briefly, then cuts out and retries, often locking out after a few tries and leaving the home with no heat while the blower pushes cold air. This is a genuine Carrier flame rectification rod built with a high-temperature Kanthal/stainless sensing element and a factory-rated ceramic insulator. A properly operating system reads a steady flame-signal current in the 1-6 microamp DC range; a dirty or wrong-depth rod reads below the board's lockout threshold. OEM matters because the rod length and bend are engineered to place the tip in the hottest part of this specific burner's flame. Generic rods frequently sit too shallow or use lower-grade insulators that leak current, producing a weak signal and nuisance lockouts even when the rest of the furnace is healthy. Install difficulty: 2 of 5. Tools: 1/4" nut driver, fine emery cloth or steel wool to clean the rod, and a multimeter capable of microamp readings to verify the flame signal. #1 safety warning: turn off the gas supply and kill power at the breaker before removing the sensor — never service the burner assembly with gas live.
