A bread maker having an oven compartment and an electric component compartment, a pair of parallel kneading drums inside the oven compartment that reverse rotary direction periodically and to which are attached opposite ends of a mixing bag containing bread ingredients, and a drum driving part in the electric component compartment rotating the kneading drums. A rotation sensing part senses a rotation rate of one of the kneading drums. A controller stops the drum driving part when the sensed rotation rate is greater than a predetermined rotation rate.
