The Goodman 0130F00038 Auxiliary Limit Switch (light blue) is a genuine OEM safety control engineered for the Amana AMES960603BNAA gas furnace. This thermally-activated switch monitors heat-exchanger and plenum temperatures, opening the circuit to shut down the burners if the furnace overheats. Installing the correct factory-matched limit prevents nuisance lockouts and protects your equipment from heat damage.
This is a genuine OEM Goodman/Amana component built to the exact trip temperature and mounting footprint of your furnace. Generic universal limit switches often carry a different set-point and can trip early or fail to protect the unit. For a safety control, we recommend OEM to keep manufacturer temperature calibration intact.
Easy (2/5). A two-wire quick-connect swap that takes most DIYers 10–15 minutes with basic hand tools. Always disconnect power before servicing. If you are not comfortable working near the heat exchanger, consult a licensed HVAC technician.
