The door safety circuit of a microwave oven is arranged to prevent a door from being opened on the case where a cooked material is unexpectedly exploded. In the microwave where a pair of door hooks are formed, a locking protrusion(10) having a hole(10A) is protruded, and a solenoid(20) is installed on the inner side of a front plate(3) and forms a shaft(20A) which is inserted into the hole(10A), the door safety circuit installs a start relay(RY1) which controls each load driving power by means of a first switch(RY11) at a relay where a second switch(RY12) is formed to be engaged with the first switch(RY11). Thus, the output power of a low voltage transducer(L.V.T) from the second switch(RY12) of the start relay(RY1) is applied to the solenoid(20) via a direct current rectifier(21).
