OEM Carrier Flame Sensor for PG8MAA036070ABJA Packaged Gas Unit

The flame sensor is a single metal rod that sits in the burner flame and confirms to the control board that ignition actually occurred. It works by flame rectification — a microamp DC current passes through the burning gas to ground, telling the board it's safe to keep the gas valve open. On your Carrier PG8MAA036070ABJA, a dirty or failing flame sensor is one of the most common no-heat callbacks. Typical symptoms: the burners light for 2-7 seconds and then snuff out, the furnace short-cycles repeatedly trying to relight, or after a few failed tries the board drops into a hard lockout and you get no heat at all. A whitish oxide or carbon film on the rod is usually the cause. This genuine Carrier sensor uses the correct Kanthal-style rod alloy, ceramic insulator, and mounting geometry so the rod sits at the proper depth and angle in the flame. A healthy unit produces a steady flame-rectification signal in the 1-6 microamp range; the OEM rod is built to hold that signal reliably as it ages. OEM matters because off-brand sensors often use thinner rods or lower-grade insulators that oxidize faster and produce a weak, drifting microamp signal. That leads to intermittent flame drop-outs and premature lockouts even when the burners are firing perfectly — turning a 5-minute part into recurring no-heat service calls. Install difficulty: 1/5. Tools needed: 1/4" nut driver, fine emery cloth or steel wool (to clean the new rod's mating surface), and a multimeter set to DC microamps to verify the signal. #1 safety warning: turn off the gas and kill power at the breaker before removing the sensor near the burner assembly.
