The purple arrows in the picture below show where they are.

After removing the old unit, it is important to clean all of the surfaces where the old unit was installed. This will help prevent rust and keep the cooling unit looking and functioning properly.

Next, transfer the boiler housing and electric heaters to the new cooling unit. If your refrigerator has a separate heating element, you will need to install that also.

Once the new cooling unit is installed, it is best to let the refrigerant and ice melt inside for about a week. This will allow the fluids to fully mix and the new cooling unit to run properly.

When you have the new unit installed, make sure that the evaporator sealing tape is on the outer periphery of the evaporator foam pack. For units where the frame member is blocking the evaporator sealing tape, it is best to put a small amount of Thermo-Mastic on the bottom of the evaporator foam pack before inserting it into the refrigerator. This helps the evaporator seal against the fridge cabinet.
