One of the most common issues cited by homeowners is that their refrigerators are running, or cycling, constantly. Depending on the age of the appliance, the culprit could be as innocent as hair, dust or debris that has accumulated in the condenser coils. This can sometimes be cleaned out relatively easily with a brush or vacuum, as long as the refrigerator is unplugged.
However, if you’re experiencing a lower internal fridge temperature, it might be because the water line is blocked or clogged, or the condenser coils are cracked. Another possible cause can be a broken condenser or evaporator fan, which can dirty the coils and necessitate replacing the condenser, fan or, depending on the extent of the damage, the coils themselves.
