Common signs that a refrigerator should be replaced include a compressor motor that is constantly running, refrigerator is too hot and increased energy bills. Homeowners should replace the refrigerator if it is more than 15 years old.
A compressor motor that is constantly running means that the thermostat is defective or the motor itself is faulty. Homeowners can begin by inspecting the thermostat and replacing it if necessary. If the compressor motor is the problem, it is often cheaper to purchase a new refrigerator. These motors are costly and difficult to replace.
A refrigerator that is too hot indicates that the motor is overcompensating. The problem is often too big to repair at this point, and it may be cheaper to purchase a new refrigerator. To prevent this from happening, clean the condenser coils located on the back of the refrigerator at least once a month. Homeowners can call in a certified appliance repair worker to inspect the unit and give a professional opinion.
Ever-increasing energy bills also mean that it is time to replace the refrigerator. Newer model refrigerators are energy efficient. They cost more but help save money on energy in the long term with a newer, more energy efficient model.
