Troubleshooting

 

 

 

 

 

 

 
Before Maintenance 
1. 

Be sure the electrical supply is 115 VAC, 60Hz, 15A and is properly grounded to protect 

maintenance personnel against electrical shock. 

2. 

Are any electrical leads loose? Danger of short circuit? If so, disconnect power. 

 
Basic Troubleshooting 

Some problems can be pinpointed through the service technician’s senses of hearing, sight and 
touch. Examples are listed below. 

 
Listen 



Listen to the user’s description of how the ice maker was operating, especially the depiction of 

unusual phenomena. Ask how the unit was operating before the user called for service and try to 
deduce the defect from the comments. 



Does the machine sound normal when it is running (like a window air conditioner)? 

 
Look 



Check the cooling system tubing, especially the welded joints. If some oil can be seen, the gas 

may be leaking resulting in less than the normal amount of ice is being produced. 



Is the cycle of the icemaking and ice harvesting normal (Does water run, is the fan running and 

is the evaporator getting cold enough)? 



Check the water system especially at the connections. Are there any water leaks? 



Check the flow of water through the water filter and if not, replace the water filter. 



Check if the ice maker was installed according to the user’s manual (level and air space). 



Inspect the ice maker to see if it needs to be cleaned. Please note, cleaning a dirty ice maker is 

not a warranty repair! 

 
Feel 



Touch the tubing at the evaporation weld, feeling the temperature. During the icemaking stage, 

it should feel cold. During the ice harvest stage, it should feel hot. 



If appropriate, touch the capillary tube or TXV tubing (near the drier). It should feel warm 

during the ice making stage. 

 

 

Troubleshooting Guide 

 
This troubleshooting guide in the user manual should be read before this guide. Be sure only when 
the trouble shooting in user manual can’t help you solve the problem, turn to this guide.
