A Guide to Common Commercial Refrigeration Problems

If you own a business that involves food and beverages, then you know how important it is to be aware of commercial refrigeration problems. In the event that your unit/s breaks down, your business might be temporarily crippled, causing you to lose customers and revenue. Not to mention, a sudden breakdown of your system can also impact your energy bills and product safety.

It’s vital, then, to keep your commercial refrigeration system in check on a regular basis. Since units typically run 24/7, you must implement preventative maintenance to ensure that everything is functioning correctly and efficiently at all hours of the day.


The importance of regular maintenance to prevent commercial refrigeration problems

Since proper maintenance is key to guaranteeing the longevity of your unit, you must make sure that it’s cleaned regularly. It’s also important to conduct a self-inspection at least once weekly just to make sure that everything is in working order. Check the defrost frequency setting and the thermostat and make sure that it’s set to the right temperature to keep food from spoiling and preventing the system from being overworked. Make it a note to also check any leaks as those might cause irreversible damage to the system.

As for tune-ups, you must enlist the help of a professional to perform them bi-yearly. This process entails the cleaning and thorough inspection of the evaporator, condensing coils, and ice makers. It also involves the checking of other key components and refrigeration levels.


Most common commercial refrigeration problems

But even if you do all the necessary steps to keep your refrigeration system from breaking down, you might still run into operational problems occasionally. Because of this, you need to be well-aware of common issues that occur with commercial refrigeration equipment so you can put a stop to the commercial refrigeration problems right away.


Here are the most common problems you should be aware of:


Formation of ice or frost

If you notice ice or frost forming inside your refrigerator, it could be a sign of poor air ventilation or maybe even a refrigerant leak. You might need to check the temperature and the frequency of the defrost cycle to see if the settings have accidentally been altered. If not, then it could be caused by loose door gaskets, a malfunctioning defrost system, or dirty fans and filters. It’s best to have a professional assess the situation and make the necessary repairs right away. Having ice or frost in your unit can only lead to further and much more severe damages.

Strange noises

The soft hum of the motors running is normal, but if there are other strange noises you notice emitting from your unit, that could mean there are internal issues you may want to look into. You might have a problem with the system’s components, including the compressor, fans, or motors. At the first sign of a concerning noise, contact a technician right away.

Inconsistent temperature

If you find that the unit is having trouble keeping food cold, you must first check if it’s set to the right temperature. But if you notice that everything is set the right way, the system might be experiencing thermostat-related problems. It could also be indicative of other issues, including dirty fans or evaporator coils, a malfunctioning compressor, or poor airflow. The smart thing to do is have a professional do a proper inspection right away.
