OEM Carrier Flame Sensor Replacement for PG8DAA048095ADJA

The flame sensor is a single metal rod that sits in the burner flame and proves to the control board that a flame is actually present after ignition. It works by flame rectification — the lit flame conducts a tiny microamp current that tells the board it's safe to keep the gas valve open. When the sensor's tip becomes coated with oxide or carbon, that signal drops and the board shuts the gas off as a safety measure. The classic homeowner symptom is a furnace that lights for a few seconds then shuts down, repeating over and over (short-cycling on flame failure), often with no steady heat and a lockout after several tries. This OEM Carrier flame sensor uses the correct rod alloy and length so it sits properly in the flame and delivers a clean microamp signal. A healthy sensor typically reads in the 1–6 microamp DC range; below roughly 0.5 µA the board will drop out. Match the mounting bracket and rod geometry to your original. OEM matters because generic sensors often use thinner or differently-alloyed rods that oxidize faster and produce a weaker, noisier flame-rectification signal — causing nuisance lockouts even when the burner is firing correctly. The OEM rod holds a stable signal far longer. Install difficulty: 1/5. Tools needed: 1/4" nut driver, fine emery cloth or a Scotch-Brite pad, and a multimeter with a microamp DC setting to verify flame current. #1 safety warning: turn off the gas at the shutoff valve AND kill power at the furnace switch before removing the sensor near the burners.
