A bread maker including a main body having an oven compartment with a front opening, a door to open and close the front opening of the oven compartment, a pair of kneading drums spaced apart from each other inside the oven compartment and winding a mixing bag filled with ingredients for bread thereon, a drum driver driving the kneading drums to rotate, a heater heating the inside of the oven compartment, and a heater driver driving the heater to operate. The bread maker includes a door sensor sensing whether the door is open or closed; and a controller controlling the drum driver and the heater driver to suspend the kneading drum and the heater, respectively, when the door sensor senses that the door is open. With this configuration, the bread maker and a method of controlling the same, suspends heaters and kneading drums when a door is open while the bread maker operates, thereby increasing safety and decreasing loss of heat and electrical energy.
