A vacuum insulated structure includes a machine compartment. A base plate is operably coupled to a bottom surface of the machine compartment. Base rails are operably coupled to the base plate and at least partially define the machine compartment. A machine plate is operably coupled to the base rails and defines a lower portion of the machine compartment. A front plate is operably coupled to a mounting wall of each of the base rails. A reed switch is operably coupled to the front plate between each of the base rails.
