The Goodman 0130F00010S Flame Sensor is a genuine OEM ignition-safety component for the ADSS800403AXAA gas furnace. The flame sensor uses flame rectification to confirm the burner has actually lit; if the control board doesn't detect a proper microamp signal, it shuts the gas valve to prevent unburned fuel from accumulating. A dirty, cracked, or degraded sensor is the most common cause of furnace short-cycling and ignition lockout.
OEM vs. Generic: The OEM Goodman sensor has the correct rod length, mounting bracket, and terminal to seat precisely in the burner assembly and produce a stable flame-current reading. Generic sensors often sit at the wrong depth in the flame envelope, causing weak or erratic signal and repeat callbacks.
Install Difficulty: Easy (1/3). Cut power to the furnace, remove one screw, unplug the lead, and swap. Clean the new rod's contact area with fine emery cloth only if needed. Restore power and verify a steady flame with no lockout.
