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.  

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.   

Compressor noises 

 

Check the unit level. Also ensure none of the pipes in 

the compressor area are touching each other or against 

the side.  

 

Compressor may be overheated.  Please check the room 

temp and ensure the range is within 65°F to 85°F.   

 

A buzzing noise may indicate improper voltage to the 

compressor. Check supply voltage.  

 

If the problem still exists, call for service.
