A home appliance includes a main body having a storage compartment, a first door hingedly coupled to the main body that opens and closes the storage compartment, and a second door that rotates relative to the first door. The second door includes a latch receptor. The first door includes a locking device with a magnetic component and a latch member. In a state in which the first door closes the storage compartment of the main body, separating the magnetic component from the main body by a first distance, the locking device disengages the latch member from the latch receptor of the second door. In a state in which the first door opens the storage compartment of the main body, separating the magnetic component from the main body by greater than the first distance, the locking device engages the latch member into the latch receptor of the second door.
