Abstract
A microwave oven equipped with a toaster and a method of controlling the same. Particularly, the microwave oven equipped with the toaster is provided with a plurality of heaters and a plurality of buttons each corresponding to one or more heaters to selectively operate the heaters provided in the toaster, thereby minimizing a power consumption resulting from an unnecessary operation of the heaters. Further, the microwave oven equipped with the toaster and the method of controlling the same limits a consumption current by preventing the toaster and the magnetron from simultaneously operating, thereby being applicable to, for example, the wall mounted microwave oven having a limited consumption current.
