The Goodman 0130F00010S Flame Sensor is a genuine OEM flame-rectification rod for Goodman ACVC800805CXAA gas furnaces. The flame sensor confirms to the control board that a flame is present after ignition; if it fails to detect flame, the board closes the gas valve as a safety measure. A dirty, oxidized, or cracked sensor is the single most common cause of furnace short-cycling and no-heat lockouts — replacing it restores reliable flame proving.
This genuine OEM Goodman flame sensor uses the correct rod length, ceramic insulator, and mounting bracket so it seats precisely in the burner flame for a strong, stable microamp signal. Generic sensors may sit too high or low in the flame, producing weak readings and repeat lockouts. OEM is recommended for dependable flame proving.
Easy. Disconnect power, unplug the single sensor wire, remove one mounting screw, and install the new sensor in the same position. Avoid touching the rod with bare fingers. One of the simplest and highest-value furnace repairs.
