The Goodman 0130F00010S Flame Sensor is a genuine OEM ignition component built for the Goodman ACSS920402BNAA gas furnace and compatible models. The flame sensor uses flame-rectification to confirm the burners have lit; if it fails to detect flame, the control board shuts the gas valve for safety. A dirty or worn flame sensor is the #1 cause of furnaces that ignite briefly then shut down (short-cycling) or fail to stay running on cold days.
OEM flame sensors use the precise rod alloy and mounting geometry that Goodman control boards expect, ensuring a reliable microamp signal. Generic sensors can produce weak or erratic flame signals, leading to intermittent lockouts that are difficult to diagnose. The genuine 0130F00010S restores factory-spec performance.
Easy. Most replacements take 10–20 minutes — disconnect power, remove the single mounting screw, swap the sensor, and reconnect the wire. No special tools required. Always cut power before servicing the furnace.
