PURPOSE: A dispenser protecting device for a refrigerator is provided to prevent malfunction though the faults of components which composes the driving protection circuit of a dispenser. CONSTITUTION: A dispenser protecting device for a refrigerator comprises a switch(SW11), a plurality of first transistors, and a plurality of second transistors. The switch controls current quantity according to a first DC power supply. The first transistors are connected to a first DC power supply and the emitters of the first transistors are grounded and the collectors of the first transistors are connected with each other. The base parts of the second transistors are connected to the plurality of first transistors. One collector of the second transistor is connected to the second DC power supply and the other one emitter of transistor is connected to the coil of the relay. |
