Commercial freezers are meant to keep multiple types of food items fresh. This means the unit must maintain its temperature so that fresh meals can be served to the customers. However, certain factors can cause problems at unexpected times resulting in the freezer dropping its temperature. As a result, you need to be aware of the basic troubleshooting tips to carry out commercial freezer repairs and fix the temperature problems without disturbing the business.

Dirty Coils

If your commercial freezer is struggling to maintain the temperature, it might be that the coils are dirty. Freezers and refrigerators normally consist of evaporator and condenser coils. Depending on the make, model, and variant, there might be one or more. These components are located at the rear of the unit and tend to accumulate dirt and dust with time.

The condenser coil is made to remove heat from the commercial freezer. If it is not maintained, the accumulation of dirt and dust can make it impossible. As a result, the coils tend to overhead and the unit has to work harder than usual to make up for the loss of cool air. However, the bigger problem is that the unit can’t maintain its temperature.

This is why it is suggested to clean the coils at least once a month. And if your commercial freezer is used more frequently, then clean it more often than once a month. Plus, coils do not come cheap either. If they frequently experience overheating, do not be surprised if you end up replacing them soon in the future.

Thermostat Malfunction

Commercial freezers come with a pre-installed thermostat that helps maintain the temperature. Although, thermostat problems are not that common in new versions but can still take place. Mostly, the problem tends to be calibration. If you were not aware, thermostats need proper calibration to be able to achieve the desired temperature.

The unit can easily lose its original settings including the calibration if it was recently repaired or some components were replaced like the control board. That said, if you notice that your commercial freezer is not having any other problems, you need to get the thermostat checked.

Once you find out it’s the culprit, call an expert to get it calibrated. Otherwise, you will simply end up spoiling expensive food items. If the thermostat shows problems after calibration, then something else is wrong or the thermostat requires a replacement.

Faulty Doors

Commercial freezers are designed to be tough and rigid units considering they are used throughout the day. This means the doors along with the components will wear out. In most cases, the issue would be caused by hinges, gaskets, etc. Fortunately, you can easily spot them and they aren’t expensive to replace either.

If the door hinge tends to be the problem, you can simply purchase a replacement and even change it yourself. The most common sign in this case is the door will not close properly. Furthermore, if there is a problem with the gasket, cool air will escape. You can check it by running your fingers around the gasket and observing any leakages.

Keep in mind that gasket leakages can be very minor in the beginning. If you are not able to notice them, it does not mean they do not exist. You need to be really careful and observant while checking the gasket. Furthermore, another sign is that the door will not lock properly as well.

Gaskets are made of plastic and rubber meaning they will wear out with time. Then again, replacing them is very easy. You need to find a replacement and install it. The installation can be tricky, so it’s better done by commercial refrigerator services Fairfax.

If this issue goes ignored, cool air will escape and warm air will make its way inside. As a result, the unit will have to work harder to maintain the temperature. On the other hand, the temperature will continue to drop and eventually lead to food spoiling.

Compressor Malfunction

If your commercial freezer is having temperature problems, one of the first things experts tend to check is the compressor. The compressor happens to be the heart of a commercial freezer. It uses refrigerant to help the unit produce cool air. However, it is not a cheap component, unlike other components inside the freezer.

Compressors are covered under warranty by manufacturers when purchasing a new unit. If maintained well, a compressor will last around 10 years on average. However, if the unit happens to be old, it might malfunction due to weak bearings and other parts.

This will simply cause malfunctioning. Unfortunately, when a compressor malfunctions, you cannot get it repaired. Even if you did, there is no guarantee it will continue working. But, if the unit is new and under warranty, you can get it replaced.

Remember, compressors rely heavily on refrigerant levels to function normally. If a leakage or any other problem is causing the refrigerant level to drop, your compressor will soon give up as well.

Therefore, make sure you perform periodic inspections and maintenance to avoid expensive problems down the road.

Poor Maintenance

Sometimes, the problem is not with the unit but with the negligence of the owner. Because commercial freezers work without any break, it is important they are maintained and looked after. As a general rule of thumb, commercial freezers should be maintained by an expert at least once a month.

However, if there is only one unit handling all the load, it might need more rounds. Most people believe they are skilled enough to perform thorough maintenance but do not know how to check the refrigerant level at the same time.

Cleaning the outside as well as the inside is a quite easy and can be done by anyone. But, when it comes to checking the components for damages, cracks, rust, leakages, etc. you are going to need an expert. This is why expert maintenance is not just limited to cleaning the equipment.

It is a thorough and detailed process of checking major components to avoid complicated situations. Plus, it is more of an investment rather than an expense.

The Unit Is Old

If nothing else works and you observe your commercial freezer is constantly experiencing problems, it most likely means it needs a replacement. A well-maintained commercial freezer will last somewhere around 10-15 years and then, you will need a replacement.

This is simply because the components get weaker with time and nothing can be done about it. If you plan on spending money on repairs and replacement, you will eventually spend more than the actual value of the unit, which is not a sensible move.

Instead, you should save the money and invest it in a new replacement. This will save you from troubles and ensure your business doesn’t get affected during busy hours.

Conclusion

Commercial freezer temperature problems can be frustrating. However, you need to be prepared for the unexpected. That said, keep the tips mentioned above in mind and make sure the unit receives expert maintenance and care.
