OEM Carrier Furnace Flame Sensor Ignition Rod for PG92SCS60120DAAA

The flame sensor is a single metal rod that sits in the burner flame and confirms to the control board that a flame is actually present after ignition. It works by flame rectification — the lit flame conducts a tiny DC microamp current that tells the board it's safe to keep the gas valve open. On your Carrier PG92SCS60120DAAA, when this sensor weakens or gets coated, the board can't 'see' the flame and shuts the gas off as a safety measure. The tell-tale symptom: the furnace lights for 3–7 seconds, then shuts down and tries again, short-cycling several times before locking out with no heat. Homeowners often describe it as 'it fires up but won't stay on.' This genuine Carrier sensor uses the correct kanthal/stainless rod length and porcelain insulator so it positions precisely in the burner flame. A healthy sensor reads roughly 4–6 microamps of flame current; anything under ~1 µA causes dropout. The ceramic insulator is rated for the high burner-compartment temperatures without cracking or developing a ground path. Why OEM matters: aftermarket sensors often use a shorter or thinner rod and lower-grade ceramic that develops micro-cracks, creating an intermittent short to ground that mimics a failing board and triggers random lockouts. The correct OEM rod restores a stable, full-strength flame signal. Install difficulty: 1 of 5 — one of the easiest furnace repairs. Tools: 1/4" nut driver (usually one screw) and fine emery cloth/scotch-brite if you only want to clean the old one first. #1 safety warning: TURN OFF THE GAS and shut the furnace breaker before reaching into the burner area. Never sand a sensor with sandpaper grit that leaves residue.
