Common Commercial Refrigeration Problems And How To Fix Them

Posted on

You may occasionally need to invest in repairs for your refrigeration units. It can be as simple as saving money by updating commercial refrigeration units with automation or repairing issues that are causing problems and energy loss. It is easy to find yourself in a position where you will need to find a solution to common refrigeration problems. The following commercial refrigeration problems are some of the issues that you might face:

Thermostats and Refrigeration Accuracy

A lot of refrigeration issues are caused by the temperature controllers, which need to be set correctly for proper temperature management. However, if the controllers are not set properly, it can create a problem in the entire system. Issues that cause commercial refrigeration inaccuracy include:

  • Thermostats failures—When a thermostat fails, it can cause the system to either over-cool, under-cool, or operate for a short time and then shut down altogether. If this happens, the entire system must be shut down and repaired.
  • The wiring is damaged—The wiring can be damaged by age, and it can cause the entire refrigeration system to stop functioning.

Thermostats can cause a lot of problems with your refrigeration system, but other issues can also contribute to their failure.

Refrigeration System Leaks and Condensate Drains

Commercial refrigeration systems can also have several issues with refrigerant gas leaks and problems with condensate drains. These types of commercial refrigeration problems include:

  • Leaking refrigerant—If a refrigeration system leaks refrigerant, it is going to run longer, and the system will not provide the accurate refrigeration that is needed.
  • Condensate drain blockage—Condensate should be drained away from the system so that the drain doesn't clog. If the drain gets blocked, the refrigerant will not be able to drain correctly, and the system will freeze up.
  • Disconnected condensate drains—If the condensate drain is not connected, the refrigerant will not be able to drain away from the system. When the refrigerant can't get out, it will continue to build up, and the system will eventually freeze up.
  • Incorrectly sized condensate drains—If the condenser drain is too small, it will not be able to handle the condensate, and it will back up.
  • Water traps and drains—Water traps and drains also need to be sized correctly. If they are not sized correctly, the condensate will not drain properly, and the system will freeze up.

Issues with leaks and condensate drains can affect many aspects of your commercial refrigeration system, as well as have an impact on its energy efficiency.

Troubleshooting Compressors

Commercial refrigeration systems use compressors, which pressurize refrigerants. When the compressor isn't functioning properly, the system won't cool. This can happen because of a broken fan or relay, weak refrigerant, or a problem with the compressor itself. There could also be issues with the motors or condensing unit that are the cause of issues with your commercial refrigeration compressor.

When dealing with commercial refrigeration problems, you want to isolate and correct the problem as soon as possible. Contact a commercial refrigeration repair service for help with the repairs and service your systems need.
