OEM Carrier Flame Sensor Rod for Gas Furnace PG8MAA036110ABJA

The flame sensor is the small single rod that tells your Carrier PG8MAA036110ABJA package unit a real flame is present. After the igniter lights the burners, this rod uses flame rectification — sensing the tiny DC microamp current that flame conducts to ground — to prove ignition. If the board doesn't see that signal within a few seconds, it shuts the gas valve as a safety lockout. That is why a dirty or failing flame sensor is the single most common no-heat call: the furnace lights for 3–7 seconds, the flame drops out, and the unit short-cycles or locks out entirely. Homeowners notice repeated clicking, brief warm air that quickly turns cold, and sometimes a lockout fault code. This is a stainless/Kanthal flame-sensing rod on a ceramic insulator with a 1/4" spade terminal. A healthy circuit produces roughly 1–6 microamps DC of flame current; anything below ~0.5 µA will trip lockout. The rod length, bend, and insulator must match so the tip sits correctly in the burner flame. Genuine OEM matters because aftermarket rods often use thinner alloy that oxidizes fast and cheaper ceramic that hairline-cracks, leaking the microamp signal to ground and causing intermittent lockouts that are maddening to diagnose. The OEM rod holds its signal strength far longer. Install difficulty: 1 of 5. Tools: 1/4" nut driver and a multimeter set to DC microamps (optional fine emery cloth — but replace, don't just sand, a worn rod). #1 safety warning: TURN OFF THE GAS and kill power at the breaker before reaching into the burner compartment.
