Abstract

A method of controlling a refrigerator including a power supply unit, an inverter applying three-phase power to a compressor is disclosed. The compressor is driven initially for a predetermined period of time. If the RPM of the compressor is not within the range between a maximum and a minimum RPM, a controller determines a malfunction of the compressor or a disconnection between the inverter and compressor during the predetermined period of time. The controller increases the number of the malfunction by one whenever the malfunction is determined. If the increased number is greater than a given number, the controller stops the compressor and alerts user to the malfunction.
