Electric appliance or refrigerator with indicator for electric controller applied thereto

A refrigerator equipped with a temperature sensor for detecting an inside temperature of the refrigerator, a temperature setting device for setting the inside temperature of the refrigerator to a desired temperature, a freezing device composed of a compressor, a condenser and an evaporator, an indicator arranged to be activated under control of an operation switch to display the inside temperature of the refrigerator detected by said temperature sensor and the desired temperature set by said temperature setting device, and an electric controller for controlling said freezing device in such a manner that the inside temperature of the refrigerator is maintained at the desired temperature set by said temperature setting device and for activating said indicator to display the inside temperature of the refrigerator detected by said temperature sensor or the desired temperature set by said temperature setting device under control of said operation switch,

• wherein said electric controller comprises memory means for memorizing a data indicative of the type of said electric controller, and means for activating said indicator to display the type of said electric controller based on the memorized data for a predetermined time when the refrigerator is connected to a source of electric power in a condition where said operation switch was closed and for disabling said indicator to display the type of said electric controller when the refrigerator is connected to the source of electric power in a condition where said operation switch is maintained in an open position.
