Scotsman Ice Machine Troubleshooting

by Ian Haynes

One of the leading ice maker brands in the US, Scotsman ice makers are usually reliable. However, like with all technology, sometimes their models can run into technical difficulties. Keeping your ice maker in top condition is important as it prolongs the life of the machine and minimizes any potential issue or damage.  

Read this guide for help with Scotsman ice machines troubleshooting.  

Scotsman Ice Machine

Ice Machine Not Turning On 

  • Power Switch Is Off Or The Cord Is Unplugged 
    Find out where your power switch and plug are from the machine’s manual. Check them carefully to ensure that the machine is securely plugged in, that the plug works, and that the switch is on. 
  • Blown Fuse Or Tripped Circuit 
    If your plug and switch are in order, check your machine’s manual for where the fuse is located. Change the fuse in the machine and plug according to manual instruction and test if that works. If not, inspect your fusebox for any broken or tripped fuses and contact an electrician if there is an issue. 
  • The Machine Transformer Could Be Open 
    If your Scotsman ice machine is not working after all of the above, locate your machine transformer and inspect it carefully for damage and contact a professional if necessary. 

Ice Machine Not Making Ice 

  • Low Room Temperature  
    If the temperature of the room with the ice machine is at or below 55 F, your ice machine may not work. Increase the temperature of the room and wait a few hours to see if that helps. 
  • Water Leak  
    Inspect your machine for any leaks and fix and clean them accordingly. If the leak cannot be fixed, we recommend calling a professional. 
  • Filter Or Condenser Is Dirty  
    Try cleaning your filter or condenser to see if removing debris helps the machine make ice. 
  • Low Refrigerant Charge  
    Inspect your machine’s refrigerant level and call a professional in if necessary. Only professionals can refill the refrigerant for safety reasons. 
  • Ice Bin Is Full  
    If you still need Scotsman home ice machine troubleshooting help at this stage, try clearing out your ice bin completely to see if that helps it make ice. 
  • Check the water supply is open  
    Inspect your water supply valve to ensure that it is open, secure, and undamaged. If it is damaged, replace it according to manual instruction or contact a professional. 
  • Check the water curtain  
    Sometimes ice falls into the water curtain and needs to be removed. If ice falls and gets stuck here, your machine may consider the ice bucket to be full. 
  • Reset the machine  
    Reset your machine by pressing and holding the right button according to your manual. 

Too Much Ice Production 

  • Faulty Thermistor  
    If you have too much ice, test your thermistor with a multimeter. If the resistance reading increases steadily, it is working perfectly. If not, you will need to replace the thermistor. 

Ice Machine Is Noisy  

  • Rattling Sound   
    Some noise is normal, and you will gradually learn what sounds your machine makes when it is healthy. However, if you want to be safe, we recommend doing the following according to your manual: 
  • Check and clean your condenser 
  • Check the reservoir and replace the pump if necessary 
  • Check and clean the evaporator plate 
  • Check the cutter grid for blockages and remove them 
  • Check the motor bearings and lubricate if necessary 
  • Replace the motor if broken or damaged. 
  • Check that there is ample airspace on all sides 
  • Check that the machine is secure and sat firmly on the floor 
  • Tighten any loose screws on the back panel 

If none of the above works, contact a professional for help. 

The Ice Is Melted Or Not Fully Formed 

  • Excess Water    
    Check the bin for wet ice or water and check the drain and drain line are clear. 
  • Insufficient/Dirty Water Supply    
    Inspect your water supply for blockages and clean according to manual instruction.  

If neither of these work, you may have a leaking internal hose that needs to be fixed by a professional.
