Disclosed is a method for controlling a microwave oven including a power supply part supplying an AC power, a high voltage transformer generating a high voltage with the AC power generated from the power supply part, a magnetron generating electromagnetic waves with the high voltage generated from the high voltage transformer, and a control signal generator part supplying a control signal to the magnetron, the method comprising the steps of setting up a reference oscillation time; measuring the time when the magnetron starts being oscillated according to the control signal; comparing the reference oscillation time with the oscillation start time; and adjusting a pulse width of the control signal where the reference oscillation time is longer than the oscillation start time. With this configuration, the temporary surge operation and the noise generation can be lowered in the hot state, that is, when the filament of the magnetron is heated to a predetermined degree of temperature over, thereby serving to enhance a stability of the circuit.
