Your commercial freezer is one of the most important kitchen appliances to deliver quality products to customers. It is designed to store food items to keep them as fresh as possible until they are served to the customer. However, if that is not the case, the food quality will be compromised. One of the most common problems amongst commercial freezers is overheating. Look for commercial refrigerator services or find these tips below that might help fix the issue.

Dirty Condenser Coils

If you observe that your commercial freezer is overheating, the first thing you might want to check is the dirty condenser coils. The reason is that with time, dust and dirt accumulation on the coils impedes their performance as the heat does not dissipate properly. Since the coils are designed to cool the refrigerant, it is important that the heat exits.

This is an important factor that needs to be considered especially during the summer season. If the coils are overheating, the unit will work harder to compensate for the loss of cool air, which will increase energy consumption as well. Ultimately, the condenser coils will give up and you will end up paying for the replacement, which could have easily been avoided by keeping them clean.

Faulty Doors

The doors on your freezer are not just regular doors. They are designed and made using special materials to prevent the air from escaping. When the doors are closed, they form a seal, which keeps the cold air inside and warm air out. With that said, if the doors tend to be faulty, the cold air will escape.

This will create an imbalance inside the freezer and the components will struggle to make up for the loss. Then again, the entire unit will work harder and consume more power in the long run. The problem with faulty doors and rubber gaskets is that while they are sometimes easily identifiable as culprits, some minor cracks and damages can make it very difficult to diagnose the problem.

In such a case, you will need to call in a professional. A faulty door might close properly but will not seal. From the outside, everything might look perfect but won’t be the same inside. Plus, damaged or worn hinges will also make it impossible for the door to align and seal properly as well.

Faulty Thermostat

Another potential culprit might be the thermostat. Since it is an electronic component that tracks the internal temperature of the unit, it will not communicate properly with the components to produce cool air if it happens to be faulty. Therefore, the freezer might show safe temperatures even though the unit might be too warm or hot.

A faulty thermostat does not only spoil expensive food items but also increases energy consumption and may lead to expensive repairs and replacements. In addition to that, you should also make sure that the freezer is not overstocked as it usually leads to improper readings as well.

Compressor Failure

Even though compressors are tough and rigid components and are usually backed by years of warranty but there is still no guarantee as to when they can give up. Usually, when the compressor is about to give up, you will hear strange and unusual noises. If you observe that the noise is running continuously, you should immediately shut down the unit and consult an expert.

Unfortunately, compressors can only be replaced and are costly. You do not have to be worried about it if you have a modern freezer. However, if it is quite old, then the chances are relatively higher.

Poor Maintenance

Finally, poor maintenance is amongst the biggest causes of an overheating commercial freezer. Commercial freezers require thorough maintenance at least once a year to prevent or avoid expensive repairs and replacements. The task is performed by experts who inspect and thoroughly clean the entire unit.

Therefore, business owners must follow the manufacturer’s recommendations to ensure the best performance and longest life of their commercial freezers.


Concluding, an overheating commercial freezer is a bad sign for business. The tips mentioned above will help you fix the issue and if not, you will need the help of a commercial freezer repairs expert. Make sure that you inspect and clean the freezer at the end of each working day to prevent complications down the road. topac
