Some of the common problems that cause refrigerators not to cool enough include dirty condenser coils, faulty evaporator fan motors and defective start relays. The homeowner should refer to the refrigerator user manual before attempting any repairs.
Condenser coils are responsible for dissipating heat from the appliance’s interior. Dirty coils limit this ability and cause the refrigerator not to cool enough. Homeowners should clean the condenser coils to fix the problem. Regularly cleaning condenser coils helps avoid the problem from occurring in the first place.
Another cause of a refrigerator not cooling enough is a faulty evaporator fan motor. The component is responsible for circulating cold air into the compartment. Homeowners should inspect the evaporator and fix or replace as needed. The number and location of the evaporator depend on the specific brand and model. However, most models use a single evaporator, usually located in the freezer side. For safety reasons, the appliance should be unplugged before inspecting the evaporator.
Finally, a defective start relay causes a refrigerator not to cool as it should. The relay is responsible for providing power to the compressor. The compressor not running at all or running intermittently is a sign that the start relay is defective. Homeowners should inspect the start relay and replace if defective.
