Abstract
An apparatus and a method for controlling operation of a compressor in a refrigerator, which are able to prevent an explosion of refrigerant caused by leakage of the refrigerant by supplying or blocking power source to electric devices in the refrigerator after detecting error of the compressor, comprise a temperature sensing unit for sensing inner temperature of the refrigerator, a door open sensing unit for sensing opened/closed status of the refrigerator door, an operating time measuring unit measuring operating time of the compressor, a microcomputer outputting a control signal based on the inner temperature, opened/closed status of the door and the operating time of the compressor, and a driving unit for supplying or blocking power source to all electric devices in the refrigerator based on the control signal.
