The genuine Goodman 0130F00038 auxiliary limit switch (light blue) is a factory OEM safety control engineered for the GCH950904CXAB gas furnace and compatible Goodman/Amana 95% AFUE models. This normally-closed thermal switch monitors heat-exchanger and cabinet temperatures, opening the low-voltage control circuit to shut down the burners if the furnace overheats — protecting the unit and your home from unsafe operation.
This is a true Goodman OEM component built to the exact trip temperature and mounting spec of your furnace. Generic aftermarket limits often carry an approximate temperature rating and looser tolerances, which can cause nuisance trips or delayed shutdowns. For a safety control, we recommend the OEM part to preserve manufacturer performance and warranty compliance.
Difficulty: Easy (DIY-friendly). Disconnect furnace power, remove the two mounting screws, transfer the wire leads to the new switch, and reinstall. Typically a 15–20 minute job with basic hand tools. Always confirm power is off before servicing.
