OEM Carrier Flame Sensor for PG9MAA048060ADKA Gas Furnace Rod

The flame sensor is the safety device that confirms your Carrier PG9MAA048060ADKA furnace actually lit. It sits in the burner flame and uses flame rectification — passing a tiny DC microamp current through the ionized flame back to the control board. When the metal rod gets coated with oxide and carbon buildup, that microamp signal drops below threshold and the board assumes there's no flame: the gas valve closes within seconds, the burners flicker on then shut off, and the furnace short-cycles or locks out with a flame-sense fault code. Classic symptom is heat that runs for 3–10 seconds then quits, over and over. This OEM sensor uses a Kanthal-style high-temperature alloy rod sized and positioned for the PG9MAA burner assembly, so it sits correctly in the flame envelope and reads a clean, stable microamp signal (a healthy furnace typically reads ~2–6 µA DC). Note this is a flame-sense rod, not a hot-surface igniter — it detects flame, it does not create it. Why OEM matters here: off-brand sensors often use a thinner rod or wrong electrode length, which sits at the edge of the flame and produces a marginal signal that nuisance-trips on windy days or as it ages. The OEM rod restores the factory flame-rectification margin. Install difficulty: 1/5. Tools: 1/4" nut driver, fine emery cloth or steel wool, and a multimeter set to DC microamps to verify the signal. SAFETY: turn off the gas supply 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.

Why Choose OEM?

OEM parts are manufactured to the exact factory specifications for your unit. Generic aftermarket alternatives may fit physically but often use lower-rated components that reduce equipment life and void manufacturer warranties. When the cost difference between OEM and generic is $10-30, the OEM part is always the smarter investment on a system worth $5,000-$15,000.
