Disuse 
In need  of  a  rather  long suspension  of  use, 
power supply plug of the refrigerator should be 
plucked  to  cut  the  power,  and  clean  the 
refrigerator  following  means  as  mentioned 
above. 
The door of the refrigerator should be open in 
suspension  of  use  to  prevent  the  small 
amount of food left producing harmful stink.
