Homeowners are greatly confused when the refrigerator does not keep cold while the freezer does. This scenario starts happening after the first five or more years of usage. If the freezer is cold but the refrigerator is warm and the evaporator coils are frosted over, there may be a defrost system problem. Several times a day the defrost heater assembly turns on for a few minutes to melt away any frost or ice that may have accumulated on the evaporator coils. If the defrost heater assembly has burned out, or the defrost thermostat or defrost control have failed the frost will build up on the coils and eventually no air will be able to travel through the coils to provide cooling. The most common cause for this condition is a problem with the defrost system. If the refrigerator's freezer is cold but the refrigerator is warm the temperature control board might be defective. The temperature control board provides the voltage to the fan motors and compressor. These boards are often misdiagnosed. Check all other components to be certain this is the cause of the problem. Don’t forget to check your appliances once or twice a year to get the right treatment in advance.
