If there is no ice production or low ice production, always check the temperature of the
freezer. The temperature must be between 0° F and 5° F for several hours to achieve proper
ice production. Some models recommend 5° F or colder for 24 hours. Water will not flow into
the icemaker until the icemold has reached operating temperatures.
When updating the control boards, replace both boards to ensure compatibility. Make
sure to replace the old Icemaker Tech Sheet with the new Tech Sheet.
Replace all parts and panels before operation
