ABSTRACT:
A microwave oven and control method thereof in which the microwave oven has a magnetron initially driven for a preset period of time to generating an output of at least 20% of a rated output of the magnetron when a cooking mode requiring a low output of less than 20% of the rated output of the magnetron is selected. Further, the magnetron performs the cooking mode by generating the low output of less than 20% of the rated output of the magnetron after the initial driving is completed. In this case, the cooking mode requiring the low output can be a thawing mode, a warming mode, etc. Further, the microwave oven of the present invention is an inverter-type microwave oven.
