When a refrigerator does not stay cold enough, it can indicate a worn out door gasket, a malfunctioning evaporator fan or dirty condenser coils. A refrigerator that does not maintain an adequate cooling temperature can cause the food stored within to go bad, so it is important to take care of the issue promptly to avoid spoilage.
One of the easiest things to check is the condition of the gaskets on the refrigerator door. To maintain the proper temperature, it’s important that the gaskets create a good seal. If they are loose or torn, they should be replaced.
An evaporator fan that is not functioning could also be causing the refrigerator to be too warm. The evaporator fan is located in the freezer compartment along with the evaporator coils. It circulates the cold air in the freezer and refrigerator compartments. If the fan and evaporator coils are frosted over, the refrigerator should be unplugged until the frost melts. If the fan is not turning, it should be replaced.
Dirty condenser coils can compromise the ability of the refrigerator to maintain the proper temperature. The condenser coils are usually located on the back of the refrigerator, near the bottom. Depending on the model, the condenser coils could be on the outside or inside of the unit behind a panel. A vacuum or brush can be used to clean any dust from the coils and restore proper functioning.
