at all

 

 

  The circuit breaker of power source is active. 

 

  The voltage is too low.    (In this case, call an electrician.) 

 

  The power switch is not ON. 

 

 The large amount of articles (load) is stored in the chamber at 

one time. 

 

  The freezer is in defrost condition.

 

The cooling is poor

 

 

  The ambient temperature is too high. 

 

  The door is not closed firmly. 

 

  The large amount of frost is built on the chamber wall. 

 

  The set temperature is not inputted properly. 

 

  The freezer is in the direct sunlight. 

 

  There is any heating source near the freezer.
