Abstract (en)
[origin: EP2009958A2] Disclosed herein is a method of preheating a microwave oven. The method includes driving a cooling fan motor for a predetermined preheating duration if a preheating operation is performed by setting a preheating temperature and inputting a preheating signal; determining whether an internal temperature of a cooking chamber reaches the preheating temperature while continuously driving all available heaters of the microwave oven; and maintaining the preheating temperature for a preheating temperature maintaining duration by driving the cooling fan motor while selectively driving the available heaters, if the internal temperature reaches the preheating temperature.
