Air Conditioner Freezing? How to Fix Frozen Refrigerator Pipes

Frozen refrigerator pipes often indicate a bigger problem with your commercial cooling system. In this article, Cold-Rite offers some DIY ways to thaw your pipes. However, you should always contact a commercial refrigerator repair company to see why your refrigerator pipes are freezing. Fixing the problem now can save you from a costly repair later.

What Causes Frozen Refrigerator Pipes?

The primary reason why your refrigerator pipes are freezing is that your evaporator coils are too cold. The evaporator is one of the main components of your commercial cooling system. The evaporator coils are filled with a refrigerant solution that cools the air in your industrial coolroom.

When your commercial cooling system is working, the evaporator absorbs heat and expels it. However, several problems with your air conditioning system can cause the evaporator coils to absorb less heat. Rather than condensation turning to a gas through the evaporator, the condensation sits on the coils and freezes. Eventually, this ice build-up can lead to frozen refrigerator pipes.

Common Problems with Commercial Cooling Systems

Now that you know why your refrigerator pipes freeze, let’s go a step further and diagnose the root problem with your commercial cooling system. The ice build-up could be due to:

  • Refrigerant leaking from the evaporator coils
  • Dirt accumulation on the evaporator coils
  • Blocked air conditioning vents
  • Clogged air filters
  • Blower fan malfunction
  • Collapsed air ducts
  • Low refrigerant solution levels

How to Prevent Freezing in Your Industrial Coolroom

Before you call your local commercial refrigerator repair team, you can try a few DIY solutions to fix your frozen refrigerator pipes. While the following tips can remedy your problem temporarily, it’s always a good idea to have a trained technician check for problematic system failures too.

Run a Defrost Cycle

Running a defrost cycle will melt all the ice that has accumulated on your pipes already. After you run the cycle, adjust the temperature of your industrial coolroom or freezer to see if a lower temperature will prevent further icing.

Check for a Dirty Air Filter or Coils

Fixing your frozen refrigerator pipes could be as simple as cleaning the air filter or vacuuming the evaporator coils. Dirt restricts airflow and forces your cooling system to work harder than it should.

Check for a Clogged Vent

A blocked or closed vent can prevent cold air from entering and warm air from leaving your industrial coolroom. Opening all of the vents can thaw the frozen evaporator coils.

Schedule a Diagnosis with a Certified Repair Technician in Sydney

Some commercial cooling system problems require a professional. If DIY solutions don’t work and you suspect your frozen refrigerator pipes may be the result of a refrigerant leak, blower motor failure or collapsed air duct, you should call Cold-Rite as soon as possible. Waiting for frozen refrigerator pipes to thaw will only result in worse problems for your industrial coolroom.

If your commercial refrigerator is too cold or you notice ice build-up, call Cold-Rite, Sydney’s best refrigerator repair specialists.
