Like the above circuit, pin 1 of CN71 suply the power. And electrical load suply the power when electricaload operated. operated refrigerator, freezer to fact comp operation And if it is needness of defrosting operation, performed comp’s electrical load is off, it is security of circuit. In fact, each operation is operated to temp. sensor and absoluteness defrosting isn’t operated with comp.
