OEM Carrier Flame Sensor for PG95SAS48080BAAA 95% Gas Furnace

The flame sensor is the single rod that proves your burners actually lit. It relies on flame rectification: the live flame conducts a small DC microamp current to the integrated control board, which uses that signal to keep the gas valve open. As the rod accumulates oxidation and silica buildup, the signal weakens — and the classic symptom appears. The furnace ignites, runs for only a few seconds, then shuts the gas off and tries again, cycling repeatedly before locking out on a flame-sense code. To a homeowner it looks like the furnace keeps starting but never delivers sustained heat, often with cold air from the registers between attempts. This sensor is a stainless-steel rod mounted on a porcelain insulator, dimensioned for the Carrier PG95 burner assembly so the tip is fully bathed in flame. A normal reading is about 1 to 6 microamps; as it drifts toward the board's minimum (roughly 0.5 µA) the unit nuisance-trips. The OEM rod preserves the exact length and insulator rating needed for a steady signal. OEM matters because the sense current is governed by rod geometry and flame immersion. Aftermarket sensors with a wrong bend or short rod sit at the cooler edge of the flame and produce a borderline reading that drops out under normal operation, causing recurring no-heat lockouts even on an otherwise healthy furnace. Install difficulty: 1 of 5. Tools: 1/4" nut driver, fine emery cloth or steel wool for cleaning, and a meter that reads DC microamps to confirm the fix. #1 safety warning: turn off 120V power at the breaker before removing the rod so the board can't energize the burners while your hands are inside the cabinet.

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.
