Common solutions for: Refrigerator runs constantly
Solution 1:
Condenser Coils are Dirty
The condenser coils are usually located under the refrigerator. They dissipate heat from the refrigerator as refrigerant passes through them. If debris accumulates on the coils, the refrigerator will have to work harder to remove the heat. If the coils are significantly dirty, the refrigerator will run constantly in an effort to cool down. Your refrigerator’s condenser coils should be cleaned twice a year.
Solution 2:
Freezer Temperature is Above 10 Degrees F (-12C)
If the freezer temperature is above 10 degrees Fahrenheit (-12C), the refrigerator will not be cold enough. If the refrigerator is not cold enough, it will work harder to cold down. As a result, it will run constantly. The freezer temperature should be set between 0 and 5 degrees Fahrenheit (-18 to -15C). If the freezer temperature is too high, ensure that the condenser coils are clear of debris and the condenser fan is working properly. In addition, check to see if frost has accumulated on the evaporator coils. If the evaporator coils are frosted over, part of the defrost system has likely failed.
