The invention discloses a microwave oven capable of preventing incorrect door opening. The microwave oven comprises a microwave oven body, and is characterized in that a left opening door is arranged on the left side of the microwave oven body; a control panel is arranged on the right side of the microwave oven body and is internally provided with a circuit board; a magnetic control lock is arranged at the junction of the left opening door and the control panel and is connected with the circuit board; after the magnetic control lock is electrified, the left opening door is tightly locked; and after the magnetic control lock is powered off, the magnetic control lock is unlocked. According to the microwave oven capable of preventing incorrect door opening, when the microwave oven is electrified to work, the magnetic control lock is used for automatically locking the left opening door of the microwave oven, so that an accident that the microwave oven is incorrectly unlocked by people, and thus microwave leakage occurs to cause injury to human bodies is effectively prevented, and the very good safety protection effect is realized.
