OEM Carrier Furnace Flame Sensor Rod Assembly for PG8JAA048135ADJA

The flame sensor in your Carrier PG8JAA048135ADJA packaged unit is a single metal rod that proves the burner is actually lit. It works by flame rectification — the lit flame conducts a tiny microamp DC current to ground, telling the control board it's safe to keep the gas valve open. When the sensor is coated in oxide, corroded, or cracked, that current drops and the board shuts off the gas as a safety response. The classic symptom is a furnace that lights for 3–7 seconds and then shuts down, repeating several times before locking out — short-cycling with no sustained heat, often worst on the season's first cold mornings. This genuine OEM sensor uses the correct rod length, ceramic insulator, and bracket geometry so the tip sits in the proper position within the burner flame for a reliable signal (typically 1–6 microamps DC on a healthy unit). The mounting hole pattern and 1/4" spade terminal match the PG8JAA burner assembly exactly. Why OEM matters: a generic rod that's the wrong length or sits at the wrong angle reads a weak signal even when the burner is firing perfectly, causing nuisance lockouts that get misdiagnosed as gas valve or control board failures. With a flame sensor, correct positioning is everything. Install difficulty: 1 of 5 — one of the easiest furnace repairs. Tools: 1/4" nut driver, fine emery cloth or steel wool, and optionally a multimeter set to microamps. #1 safety warning: shut off the gas supply and kill power at the disconnect before reaching into the burner compartment.
