Not plugged in. 
The appliance is turned off. 
The circuit breaker tripped or a blown fuse.

 

Wine Chiller is not cold enough.

 

Check the temperature control setting. 
External environment may require a higher 
setting. 
The door is opened too often. 
The door is not closed completely. 
The door gasket does not seal properly.

 

Turns on and off frequently.

 

The room temperature is hotter than normal. 
A large amount of contents has been added to the 
wine chiller. 
The door is opened too often. 
The door is not closed completely. 
The temperature control is not set correctly. 
The door gasket does not seal properly.

 

The light does not work.

 

Not plugged in. 
The circuit breaker tripped or a blown fuse.

Vibrations.

 

Check to assure that the Wine Chiller is level.

 

The Wine Chiller seems to make too much noise.

 

The rattling noise may come from the flow of the 
refrigerant, which is normal. 
As each cycle ends, you may hear gurgling 
sounds caused by the flow of refrigerant in your 
Wine Chiller. 
Contraction and expansion of the inside walls 
may cause popping and crackling noises. 
The Wine Chiller is not level.

The door will not close properly.

 

The Wine Chiller is not level. 
The door was reversed and not properly installed.
