Refrigerators and freezers are some of the most useful appliances we can have in our homes today. If these appliances stop working, we can get greatly inconvenienced as far as food preservation is concerned. For a refrigerator and freezer not getting cold enough, it is one of the most common problems that homeowners experience with refrigeration appliances. So it is important to understand the various causes of problems or reasons why sometimes a refrigerator or freezer won’t get cold enough.
Damaged door gaskets
If the gasket on the door of the refrigerator or freezer suffers any damage that makes it not to seal properly when you close the door, then you’re going to have warm air getting inside refrigerator or freezer compartments and they won’t get cold enough. It is important to inspect the gaskets to make sure they are not torn or getting loose to a point of interfering with the door closing properly and leaking cold air.
Build-up of dirt on condenser coils
The condenser coils are supposed to help the refrigerator to get rid of the warm temperatures absorbed from the food stored inside the refrigerator. If that builds up around the condenser coil, they cannot efficiently cool down the refrigerant. So that’s another reason you may have the problem of a refrigerator and freezer not cold enough. These condenser coils are located in the back or the underside of the refrigerator, so you should access them while the appliance is unplugged from the power source. The best way to clean the dirt off is to pass a vacuum cleaner over the coils.
Frost buildup on evaporator coils
Sometimes moisture inside the refrigerator or freezer can form ice or frost on the evaporator coils. If that happens, it interferes with heat transfer as the evaporator coils are supposed to absorb warm temperatures from stored food. The defrost system is supposed to start periodically and melt any buildup of ice or frost on evaporator coils. If that doesn’t happen, then the evaporator coils will not efficiently absorb warm temperatures and the refrigerator or freezer will not get cold enough. With the frost build-up, the evaporator fan will also not work properly. It will probably hit the frost with its blade and start making a lot of noise when it becomes unbalanced. The evaporator fan is supposed to blow cold air to flow through paths on the evaporator coils in the absence of frost build-up. The defrost system failure can be due to failure of its component parts, that is, the defrost heater or the defrost sensor.
Faulty thermostat and incorrect temperature control
Sometimes the freezer or refrigerator will not cool properly if the thermostat is faulty or is not set to the correct temperature. You can locate the thermostat under the freezer or the refrigerator depending on your brand or model of appliance. For the refrigerator, the correct temperature setting should be 40°F or lower, while for the freezer it should be set at 0°F.
While there are many possible reasons to explain the problem of any refrigerator or freezer not cooling properly, you will realize that some problems will require simple fixes while others must be solved by experienced appliance service professionals. So make sure to call an appliance repair technician if the problem making your refrigerator or freezer not to cool well is beyond your technical skills and abilities.
