OEM Carrier Flame Sensor for PG8MAA048110ABJA Gas Package Unit

The flame sensor in your PG8MAA048110ABJA package unit is a single metal rod that confirms a flame is actually present after ignition. It works by flame rectification — the lit burner conducts a tiny microamp current from the rod to ground, telling the control board it is safe to keep the gas valve open. When the sensor is dirty, oxidized or worn, the board can no longer 'see' the flame and shuts the gas off as a safety response. The classic symptom is a furnace that lights normally, burns for 3 to 7 seconds, then snuffs out — repeating two or three times before locking out with no heat. This OEM sensor uses a heat-resistant Kanthal/stainless rod sized and bent to Carrier's exact geometry so the flame fully envelops the tip. Typical healthy flame-sense current runs roughly 1–6 microamps; below about 0.5 µA the board drops out. Correct rod length and mounting depth are what make that signal stable. Why OEM: an aftermarket rod with the wrong length, bend or mounting position sits at the edge of the flame and produces a weak, drifting microamp reading — giving you the same short-cycling you were trying to fix. The genuine sensor restores a strong, repeatable signal. Install difficulty: 1 of 5 — one of the easiest furnace repairs. Tools: 1/4" or 5/16" nut driver and fine emery cloth (light cleaning sometimes revives a marginal sensor). #1 safety warning: shut off the gas and kill the power before removing the sensor near the burner assembly.
