Common Problems With Commercial Refrigerators

Posted on: 20 October 2020


If you run a business where you need to keep things cold all the time, your commercial refrigeration unit is most likely one of the most valuable pieces of equipment you can invest in. Like everything else in your business though, it needs to be serviced and maintained properly, or else it will deteriorate and need to be replaced ahead of its time.

Fortunately, the issues that plague commercial refrigeration units are somewhat common — so common that we are able to list out several of them below for you to examine. If you see any of them occurring in your business, contact a local technician to work on it immediately before the problem gets any worse.

Refrigerator Not Holding Temperature

The main reason you have a refrigeration unit is to keep things cool; if it's not doing that, something needs to be fixed. Before you call a technician, check a few things first to see if you can solve the issue yourself. First, make sure that the unit is at least a few inches away from the wall to provide the proper airflow needed for refrigeration. Next, check the door to make sure that it sealed, and finally, use an external thermometer to verify the temperature reading that you're getting from the fridge itself. If none of these present a problem, find refrigeration contractors in your area that you trust to work on the issue.

Ice in the Drain Pan

Your drain pan is designed to remove the water that is condensing inside of your refrigerator away from your unit and distribute it outside to avoid water damage and mold buildup. If you see ice chunks in it, that means there's most likely a blockage in the drain pan that is causing the water to build up inside and freeze before it gets emitted outside. Remove the clog, or contact a refrigeration expert to do it for you, and the problem should be solved.

Ice Building Up Inside the Unit

Most commercial refrigerators should have some ice buildup on the inside. If it's excessive, it could be your evaporator fan that's causing the problem. A simple reset should do the trick: turn off the unit and allow it to thaw completely. Next, check for any buildup that may be on the evaporator coils that's blocking the airflow and causing them to freeze. If only some of the coils are frozen, you'll need to have a refrigeration contractor charge up the unit.
