3 Major Commercial Freezer Problems – How to Identify & What to Do

Commercial Freezer Problems 101: Business establishments need to take their commercial refrigeration seriously. There is nothing more frustrating than dealing with a short-cycling freezer, or one that consistently produces annoying sounds. The chances are that your commercial freezer is no longer in top shape and working condition. That would affect your commercial foods and beverages that need refrigeration and impact your business.

Read on to learn about 3 of the most common, major commercial freezer problems and what you can do to troubleshoot or identify the problem before hiring a commercial refrigeration specialist for repair.

3 Major Commercial Freezer Problems

Here are the top commercial freezer problems you might encounter along with what you can do about them. Read below before you hire a commercial refrigeration repair service.

1. Water Leaks

It’s common for your freezer to have a small amount of water leaking on the floor. It happens when your defrost drain has frozen over and needs to be defrosted and cleaned. The water leaks may also have to do with dropped ice cubes that have melted and spilled drinks after having filled a glass.

When confronted with this problem, there are a few things you can do. First, examine the water line from the shutoff valve to the freezer to see if there’s any problem. If the problem has to do with the freezer itself, see if there’s an excessive amount of frost forming on the evaporative coils or if the water isn’t evaporating in the condensation pan. The chances are that certain parts need to be repaired or replaced.

2. Frost Build-Up

There are instances when you encounter frost build-up in your freezer. When faced with this problem, you may need to have the defrost heater repaired or replaced. This issue may have to do with a few correctable conditions.

First, the frost may occur because the door is not closing properly. Make sure to keep the freezer door closed all the time. Second, the freezer temperature may have been set too low. Be sure that the freezer temperature is around 0°F (-18°C), and the refrigerator is around 37°F (3°C). Lastly, the frost on the back of the freezer section may have an issue with the defrost cycle. Further troubleshooting is required to see the underlying problem and make the necessary fix.

3. Unusual Noises

Sounds produced by your commercial freezer may be caused by a handful of reasons. First, clicking from the ice maker indicates it harvests a batch of ice. Second, the appliance is going through a defrost cycle if it produces sizzling sounds. Third, gurgling occurs when water drains off the evaporative coil. Finally, swishing sounds happen when the multiple-speed fan ramps up to high speed.

If you hear unusual noises, apart from those discussed above, there’s a problem in some parts of your freezer. Having your commercial refrigeration inspected or repaired is necessary.


Commercial freezer problems can develop at any time. To minimize machine downtime for repairs, equipment needs to be checked and maintained to ensure it’s in top shape and working condition. As outlined above, be wary of common issues with your commercial freezer, such as water leaks, frost build-up, and unusual noises, and be sure to follow the valuable tips discussed above. The condition of your commercial refrigeration can impact your business negatively.
