Question & Answer 

 

Main Problem 

Answer to the problem 

The internal 
temperature is too high 
or too low. 

It is a bit relevant to the surrounding environmental temperature. When the 
internal temperature is too high or too low, we can solve this problem by 
adjusting the controlling temperature. 

There is a sweeper 
phenomenon within the 
refrigerator after a 
certain duration of the 
its operation. 

A little sweeper can be drained off periodically and be wiped off by a towel. 
If there is a lot more sweeper, we can check whether the  drainpipe or 
other drainage are blocked and may get it though with a piece of fine wire.
