QUICK TROUBLESHOOTING GUIDE 

 

Check these items before calling for service.  

PROBLEM: 

POSSIBLE CAUSE / SOULTIONS: 

Unit does not run 

  Electrical circuit is not 110-120V 60Hz. 

  The power cord is not plugged in. 

  No power at electrical outlet. Check to make sure 

breaker is not tripped or fuse is not blown. Additionally, 
make sure unit is not plugged into a Ground Fault Circuit 
Interrupter (GFCI) type of outlet.  

Unit does not maintain at the 
proper temperature 

  Check the room temperature.  We recommend the 

refrigerator or freezer should be placed in the air 
conditioned room between 65°F to 85°F.  If the room 
temp is too warm, the refrigerator or freezer may not be 
able to maintain the interior temp at proper range.   

  Door is not closed properly. 

  Amount of stored product is overloaded. 

  Product replacements are pushed against rear wall or 

interrupted the proper refrigerator air circulation.  For the 
proper air circulation, place the products evenly on each 
shelf.  Do not push against the refrigerator’s rear or side 
walls. 

  Evaporator is blocked by frost or ice.  Remove the 

products, unplug the refrigerator or freezer power, and 
allow the unit to defrost.  If the problem still exists, call 
for service.  

  3

rd

 party thermometer is placed incorrectly. For proper 

temperature monitoring, the thermometer should be 
place in the middle of refrigerator. 

 

PLEASE NOTE

!  Prior to shipment, each refrigerator and 

freezer has been calibrated and tested at proper temperature 
range. 

Appliance runs too long 

  Prolong door openings. 

  Control set too cold. 

  Room temperature is high which will make the unit work 

harder to keep cool.  

Temperature of external wall 
surface is warm 

  The exterior walls can be as much as 30 degrees 

warmer than room temperature due to the embedded 
condenser coils. This is normal when the unit is 
operating.
