Problems that may require a professional repairman include a refrigerator turning on and off repeatedly or running constantly without ever becoming cold. Refrigerators that sweat may require a professional to repair the mullion heater that controls condensation on the refrigerator. It is advisable to have a professional replace the refrigerant in a refrigerator, due to the expense and legal complexities involved in disposing of used refrigerants.

Because of the complexity of a refrigerator's mechanisms, problems that truly require a professional repairman are difficult to separate from problems that owners can fix themselves without going through a process of elimination. For example, while a defective compressor sometimes leads to a freezer turning itself on and off rapidly, these problems can also be caused by a blocked condenser fan or dirty compressor coils as well.

It is advisable to research potential causes of a freezer issue and exhaust all of the possible solutions before calling in a repairman to avoid unnecessary costs.
