Reasons Why Your Commercial Refrigeration Isn't Cooling

Commercial refrigerators are necessary for various enterprises, including restaurants, coffee shops, and caterers. They exist solely to keep raw materials, fresh food, and anything else perishable from the cold. Sadly, old equipment will be unable to maintain the required low temperature, resulting in spoiling and foodborne disease.

Several things may go wrong with these machines. Continue reading to learn about the most common causes of your commercial refrigerator not cooling—and what you can do about it.

  •  The door doesn't close properly.

The commercial refrigerator door is the most important part of the cooling system. If the door is not closed correctly, it will be unable to keep the cold air inside, and the food will not be kept at the right temperature. This can lead to food spoilage and even health risks. It is important to check your commercial refrigerator's door regularly and ensure that it closes properly to ensure it works correctly. Depending on whether it is or is not, you should contact a professional to have it fixed.

  •  Thermostat Options 

Sometimes the simplest changes are the most effective solutions. Examine your commercial refrigerator's thermostat settings; possibly, the power was recently cut off and reconnected, or the thermostat was cranked up and set a few degrees over the appropriate cooling temperature.


Even with smart thermostats that automatically modify the temperature setting, having human eyes double-check the refrigeration unit to verify that things are correctly stored in the appropriate environment is beneficial.

  •  Blocked Vents 

Blocked vents might prevent air from moving correctly, causing the fridge to overheat. If the vents are blocked, it can cause the compressor to overheat and shut down, preventing the fridge from cooling. Also, blocked vents can cause the evaporator coils to freeze, preventing the fridge from cooling. To fix this issue, make sure all vents are clear and unobstructed.

  •  Dirty condenser coils

A lack of cooling is the most common issue regarding commercial refrigeration. This can be caused for several reasons, the most frequent of which are dirty condenser coils. Condenser coils are responsible for expelling heat from the refrigeration system, and they can't do their job effectively if they become blocked with dirt and debris. This can lead to a decrease in cooling efficiency and an increase in energy consumption. Cleaning the condenser coils is important to ensure your commercial fridge runs properly. This can be done by using a vacuum cleaner or a coil cleaning brush to remove the dirt and debris that has built up on the coils. Doing this will help ensure your commercial fridge is running efficiently and cooling properly.

  •  Compressor problems

Commercial refrigerators are essential for businesses that store food and beverages at a specific temperature. The thermostat is in a position to control the temperature of the refrigerator. However, if the compressor isn't working correctly, the refrigerator won't cool. If it's not working properly, the compressor won't turn on, and the refrigerator won't cool. There are several potential causes of compressor problems, including a faulty thermostat, a dirty condenser coil, or a malfunctioning start relay.

You should test the thermostat by measuring the voltage using a multimeter. If the voltage is too low, the thermostat will most likely need to be changed. The condenser coil is in charge of removing heat from the refrigerator. If the condenser coil is dirty or debris-filled, you can use a vacuum cleaner to remove it.

The start relay is responsible for turning the compressor on and off. If it's not working properly, the compressor won't be able to start, and the refrigerator won't cool. To check the start relay, you can use a multimeter to measure the voltage. You may need to replace the start relay if the voltage is too low. If your commercial refrigerator isn't cooling, it's likely due to a problem with the compressor. You can check the thermostat, condenser coil, and relay to diagnose the problem. If any of these components are not working correctly, they must be replaced for the refrigerator to cool properly.


 When a commercial refrigerator is not cooling properly, it can be a sign that it is time for a new one. If you need to repair the fridge regularly, Then it is better to invest in a new refrigerator. Replacing your commercial refrigerator can be a great way to save money and time in the long run. A new commercial refrigerator can provide more efficient cooling and help you save money in the long run. It can also help you avoid the hassle of frequent repairs. When shopping for a new commercial refrigerator, consider the size and features that best suit your needs. Make sure to look for an energy-efficient model with a good warranty. Investing in a new model can help you avoid the hassle of frequent repairs and provide more efficient cooling. Additionally, you should research the manufacturer's reputation and read customer reviews to ensure you are getting a quality product.
