It is a kenmore elite model # 795.72372.312. The best course of action to rectify this problem is to have a fan with a high RPM (rotations per minute) installed just behind the opening space behind the fridge in order to increase the air flow in the chamber of the refrigerator. Have removed the water filter and still no water flow. To remove a build up of ice, use a hair dryer set to "low". With the quick freeze door so small fruits like strawberries and vegetables will freeze much faster. 3) Heat will continue to flow from the warmer object to the colder object until their temperatures are equal. A clear view of the freezer compartment was achieved using two specially constructed, transparent and insulated glass windows mounted on the side and top walls of the refrigerator. The purpose of the burst valve is to stop the water flow in the event the water line bursts and begins to flood the house. I just checked the fridge. There may still be a small amount of cooling because the frost over the coils, but with no air flow over the coils.This frost should be removed by manual defrosting or automatic defrost (in frost free refrigerators) for proper cooling inside refrigerator… Once this occurs, air is no longer able to travel through the coils and provide cold air to the fridge or freezer. Amana Br18VE #9908164502, the bottom freezer has cold air entering and is below frezzing but the top refrigerator compartment hs no air flow at all.
