When your commercial freezer freezes, there are several possible causes. One cause may be a faulty seal. Old joints are not sealed properly, allowing outside air to enter. Another cause may be a faulty door or hinge. Problematic door closers may not catch the roller sufficiently on the hook or the hydraulic mechanism may leak.
Also, the main control board may be faulty. You may also need to replace the thermostat. The condensation pan may also leak or be cracked. A professional freezer repair company will be able to fix these issues. Although some problems can be easily corrected, others may require major replacement or repair.
The first step in a commercial freezer repair job is to diagnose the cause of the problem. If the compressor is not sending power to the refrigeration system, it will not be able to cool the freezer. If so, the compressor may be faulty. Check continuity of all parts. If a component is faulty or smells burnt, replace it. Also check the evaporator fan. If it does not rattle or rattle when shaken, it is faulty.
Other potential causes of commercial freezer failure include a faulty compressor or faulty thermostat. A faulty thermostat will not regulate the temperature accurately. Likewise, a dirty compressor coil will cause the temperature to drop. Fortunately, these problems are simple to fix.
