Verify that the Estate refrigerator is plugged into a working power supply with a three-prong outlet if the refrigerator does not seem to have power. Three-prong adapters can be purchased at many hardware or grocery stores. Replace the fuse or reset the circuit breaker if needed.
Ensure the thermostat is turned to a cold temperature if items in the refrigerator seem too warm. Avoid opening the refrigerator door frequently, as this warms the internal temperature and may affect overall food temperature.
Adjust the thermostat to a warmer temperature if frost appears on the outside of food products or food is frozen. Allow several hours for the new temperature to take effect inside the unit.
Push refrigerator and freezer shelves into position and the crisper cover closed if the doors do not close completely. Wipe down the door seal with a clean, wet cloth and then dry it with a clean towel. This removes excess dirt and debris that may prevent the seal from closing all the way.
Ensure the water shutoff valve is completely open and the water line is straight if ice is not being produced or the ice cubes are very small or hollow.
Contact a service technician for assistance if the above methods do not resolve the issue.
