OEM Carrier Flame Sensor for PG8MAA048110AAJA Gas Package Unit

The flame sensor in your PG8MAA048110AAJA package unit is a slim metal rod that verifies a real flame after the burners light. Through flame rectification, the lit flame conducts a small microamp current from the rod to ground, signaling the control board that it is safe to keep the gas flowing. When the rod becomes coated with oxidation or carbon, that signal weakens and the board shuts off the gas as a safety measure. The telltale symptom is a furnace that ignites, burns for only a handful of seconds, then goes out — cycling two or three times before locking out and leaving you with no heat. This OEM sensor uses a heat-tolerant Kanthal/stainless rod formed to Carrier's precise length and bend so the burner flame fully surrounds the tip. A healthy flame-sense reading typically falls around 1–6 microamps; once it drops near 0.5 µA the board drops the call. Correct geometry and mounting depth are what keep that microamp signal strong and stable. Why OEM: an aftermarket rod of the wrong length or shape rides the edge of the flame and produces a weak, wandering signal — recreating the exact short-cycling you set out to cure. The genuine sensor delivers a clean, repeatable reading. Install difficulty: 1 of 5 — among the simplest furnace fixes. Tools: 1/4" or 5/16" nut driver and fine emery cloth for light cleaning of a marginal rod. #1 safety warning: turn off the gas supply and the electrical power before working near the burner assembly.
