OEM Carrier Flame Sensor Rod for Gas Furnace PG9YAA036060ABSS

The flame sensor is a single metal rod that sits in the burner flame and confirms to the furnace control board that gas is actually burning. It works by flame rectification — the lit flame conducts a tiny microamp DC current the board watches for. If the board doesn't see that current within a few seconds of the gas valve opening, it closes the valve to keep raw gas from filling your heat exchanger. A dirty or failing flame sensor is the #1 cause of furnace short-cycling: the burners light, run 3–8 seconds, then shut off, and the furnace relights again and again before locking out. Homeowners notice short bursts of heat, repeated clicking and relighting, and eventually no heat at all. Specs: this OEM Carrier flame sensor has the correct rod length, ceramic insulator, and connector for the PG9YAA platform and generates a clean flame-rectification signal — a healthy unit reads roughly 4–6 microamps DC while in flame. The OEM ceramic base resists tracking and cracking at burner temperatures. Why OEM matters: aftermarket sensors often use thinner rods and lower-grade ceramic insulators that crack, short to ground, or oxidize quickly — re-introducing the very short-cycling fault you're trying to fix. A correctly shaped OEM rod sits at the right depth in the flame for a stable, strong signal. Install difficulty: 1/5 — one of the easiest furnace repairs. Tools: 1/4" nut driver, plus fine steel wool or emery cloth if you'd rather clean than replace. SAFETY: turn off the gas and shut power at the breaker before removing the sensor, and let the burner assembly cool so you don't burn your hand.
