MOISTURE DURING THE SUMMER MONTHS 

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 will 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. 

PROBLEM: 

POSSIBLE CAUSE / SOULTIONS: 

Compressor noises 

 

Compressor may be overheated.  Please check the room 
temp and ensure the range is within 65°F to 85°F.  If the 
problem still exists, call for service. 

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. 

Odor inside the unit 

 

Interior needs to be cleaned.  See section on 
maintenance and cleaning in this manual.  

 

Make sure product containers are tightly sealed to 
prevent leakage 

Door will not close 

 

The unit is not level. Refer to the Leveling section at the 
beginning of this manual 

 

Check for dirt and debris or items passing through the 
door seal.
