Method for controlling defrosting in a microwave oven having an infrared sensor, including the steps of (a) controlling a first defrosting up to a preset temperature upon reception of defrosting key application from a user, (b) turning over frozen food upon completion of the first defrosting, and (c) periodically detecting a surface temperature of the turned over frozen food by using the infrared sensor, and controlling a second defrosting according to the detected surface temperature and temperature variation, whereby permitting an optimal defrosting of the frozen food by making voltage application condition control according to the periodic detection of a surface temperature of frozen food by an infrared sensor, not only in the first defrosting when one side of the frozen food is heated, but also in the second defrosting after the turn over of the frozen food, and to prevent a pre-mature, or excessive defrosting by making defrosting control based on the surface temperature and the temperature variation of the frozen food.
