What should the water pressure be in the water line for the ice maker?
Do not attempt service or replace parts of the appliance unless referred to in the owner's manual. Follow all safety precautions provided in the owner's manual.
There should be 20 to 100 pounds per square inch (PSI) of water pressure. If the refrigerator has a factory installed water filter, the water pressure should be 35 to 120 PSI.
