The genuine OEM Goodman 0130F00038 Auxiliary Limit Switch (light blue) is a thermal safety control for the AMVM961005DXAA 96% AFUE furnace. This normally-closed high-limit switch monitors temperature at a secondary location in the furnace and opens the circuit to shut down the burners if it detects an overheat condition — protecting the heat exchanger and blower assembly from damage.
The light-blue color code corresponds to a specific factory trip and reset temperature. This is a safety device — a generic switch with a different set point can either nuisance-trip or, worse, fail to open when it should. Always match the OEM part and color code exactly; never substitute an unrated equivalent.
Easy. Usually two mounting screws and two push-on spade terminals. Cut power at the disconnect, transfer the wires, and remount. A quick repair — but because it is a combustion safety component, verification by a licensed HVAC tech is recommended.
Fits Amana and Goodman furnaces sharing this cabinet. Confirm the color code and part number against the unit before ordering.
