PROBLEM: 

POSSIBLE CAUSE / SOULTIONS: 

Moisture collects inside 

 

Door gasket is not sealing properly. Check for debris, 
cracks, and items passing through door at the gasket.                                                             

 

The refrigerator or freezer is facing a doorway or is 
underneath of air conditioning vent. Relocate the unit or 
redirect air vent. 

 

Too many door openings. Minimize time door is open. 

 

Hot, humid weather increases condensation. 

 

Make sure there is a water trap (U-shaped loop) in the 
drain tube near the compressor. This will “trap” a small 
amount of water in the loop and prevent air from 
entering the chamber through the tube.  

Moisture collects on outside 
surface 

 

Hot, humid weather increases condensation. 

 

As humidity decreases, moisture will disappear. 

The display shows “SO” and 
the compressor does not run 

 

The temperature sensor is open. Call for service.                                                                                                                                                                                                                                                                                                                                                       

The display shows “SC” and 
the compressor does not run 

 

The temperature sensor is shorted. Call for service.  

The display shows “HH” and 
the compressor does not run 

 

The ambient temperature is above 40C/104F. Stop using 
immediately. 

The display shows “LL” and the 
compressor does not run 

 

The ambient temperature is below -40C/-40F. Stop using 
immediately.  

MOISTURE DURING THE SUMMER SEASON 

The amount of moisture, condensation, or high humidity related issues increase during the summer 
and,  in  most  cases,  will  self-resolve  when  the  weather  cools  down.    Please  note  a  refrigeration 
system does NOT generate moisture or water but simply condenses the moisture that is already in 
the chamber. Keeping the unit in an air conditioned, low humidity space will resolve many issues. 
Other things you should check 

1.

 

Location of the refrigerator (See Quick Troubleshooting Guide above) 

2.

 

Door sealing and frequency of door opening event (See Quick Troubleshooting Guide above) 

3.

 

Make  sure  there  is  a  water  trap  (U-shaped  loop)  in  the  drain  tube  near  the  end.  This  will 
“trap”  a  small  amount  of  water  in  the  loop  and  prevent  air  from  entering  the  chamber 
through the tube.  

 
BEFORE CALLING THE MANUFACTURER’S TECHNICAL SUPPORT DEPARTMENT, 

please have the 

unit’s model and serial number ready as well as the problem description.  The model and serial 
number  is  located  on the  serial tag  which  can  be  found  on  the  interior  left upper  wall  of the 
unit.
