OEM Carrier Gas Furnace Flame Sensor Rod for PG95XAT36040BAAA

The flame sensor in your PG95XAT36040BAAA furnace is a single metal rod that sits in the burner flame and confirms, electronically, that the burners actually lit. It works by flame rectification: the control board sends a small AC signal down the rod and the ionized flame conducts a tiny DC microamp current back. If that current is too low, the board assumes there's no flame and shuts the gas valve within seconds as a safety measure. The classic failure symptom is short-cycling on ignition — the burners light for 3 to 7 seconds, then snuff out, and the furnace retries several times before locking out and leaving you with no heat. A coated or weak sensor is the single most common cause of this complaint. This genuine Carrier sensor uses the correct rod alloy, length, and ceramic insulator so it generates a full, stable flame-rectification signal (typically several microamps DC) that the PG95XAT board reads reliably. OEM matters because aftermarket rods often use a shorter or thinner element and cheaper insulators that crack with heat cycling, producing a weak or erratic microamp signal that triggers premature lockouts even on a perfectly good flame. Installation difficulty: 1 of 5 — one of the easiest furnace repairs. Tools needed: 1/4" nut driver and fine emery cloth or a non-abrasive pad to clean the rod (never sandpaper, which leaves residue). #1 safety warning: turn off the furnace breaker and shut off the gas supply before removing the sensor from the burner assembly.
