A cooling unit includes a cabinet with a cooling chamber, a refrigeration system including an evaporator mounted, a compressor, a condenser, and a controller for controlling the cooling unit. The controller has a memory, a processor and an output interface. The controller monitors at least one parameter of the cooling unit, logs in the memory data corresponding to the at least one parameter, and outputs the logged data via the output interface. The cooling unit can include a sensor that monitors a parameter that is logged in memory. The sensor can be a temperature sensor. The logged data can be compared to stored error conditions to detect whether an error condition has occurred. If an error condition has occurred, an error code is logged in memory and can be outputted via the output interface.

We claim: 1. A cooling unit, comprising:a cabinet providing at least one cooling chamber therein;a refrigeration system including an evaporator, a compressor receiving return refrigerant from the evaporator, a condenser coupled to the compressor and to the evaporator through a restriction; anda controller for controlling the cooling unit, the controller having a memory, a processor and an output interface, the controller being configured to monitor at least one parameter of the cooling unit, log in the memory data corresponding to the at least one parameter, and output the logged data via the output interface;at least one sensor mounted within the cabinet to generate an input signal corresponding to at least one parameter;wherein the controller is configured to receive the input signal from the at least sensor and log in the memory data corresponding to the at least one parameter of the input signal thereby including the plurality of data corresponding to the at least one parameter of the input signal in the logged data, wherein a plurality of error conditions are stored in the memory and the controller is configured to compare the logged data to the plurality of error conditions to detect whether one of a plurality of error conditions has occurred and log in the memory an error code corresponding to one of the plurality of error conditions when the one of the plurality of error conditions has been detected, and wherein the controller is configured to output a generic error indicator via the output interface when the error code is logged in the memory.
