Abstract
A system includes a door sensor that provides a status of whether a door of a refrigeration system is open or closed, a temperature sensor that measures a temperature of a food compartment of the refrigeration system, a power sensor that measures an amount of power consumed by the refrigeration system, and a compressor sensor that provides acoustic data about a compressor of the refrigeration system. The system further includes a remote computing system configured to send an alert indicating that the refrigeration system needs servicing when the temperature of the food compartment of the refrigeration system is determined to be above a predetermined temperature while: the door of the refrigeration system is closed, the amount of power consumed by the refrigeration system is within a predetermined power range, and acoustic signals of the compressor of the refrigeration system are within a predetermined acoustic range.
