The Goodman 0130F00010S Flame Sensor is a genuine OEM replacement engineered for GCH91155DXAA gas furnaces and compatible Goodman/Amana models. The flame sensor uses flame rectification to confirm the burner has ignited; if the control board doesn't see a stable microamp signal, it shuts off gas as a safety measure. A dirty, cracked, or failed sensor is the single most common cause of short-cycling and "ignites then shuts off" furnace faults.
This genuine OEM sensor matches the factory rod length, insulator, and mounting geometry exactly, ensuring the correct flame-current reading the control board expects. Universal aftermarket sensors often require bending or bracket modification and can produce weak or unstable signals. Choose OEM for a guaranteed drop-in fit and reliable flame proving.
Rated Easy (1/5) — typically a single mounting screw and one wire connector. Always shut off power and gas before servicing. Most homeowners complete this repair in under 15 minutes with a nut driver.
