One of the critical components of any food service establishment, like a restaurant, is a commercial refrigeration unit. While most kitchens trust brands due to their long-lastingness and better service, you must ensure their maintenance and upkeep as well if the food ingredients kept inside are not chilling enough. After all, industrial refrigerators have a sole objective: cold storage of raw ingredients, beverages, fresh food, and other perishables. However, all the various cooling devices can't perform fundamental functions flawlessly without maintenance for a long duration. There can be multiple reasons for your commercial chilling device not cooling correctly. It can be due to lack of maintenance & repairs, defective thermostat or dirty condenser coils. In the following lines, we will check out the likely reasons for this phenomenon that prevent optimal functioning.

Filthy Condenser Coils

Unclean condenser coils are one of the most frequent reasons for the non-cooling of premium industrial chilling equipment. These coils help chill the refrigerant and supply cool air to the fridge. However, the coils' functionality may get impaired due to contaminants like accumulated dust, dirt and grease. This issue can result in higher temperatures and food spoilage in retail refrigerator storage containers. Every machine needs proper maintenance to continue offering above-average functionality. Therefore, the staff must maintain the cooling device's temperature by cleaning the condenser coils every three months. Once you have removed the device plugs and taken out all the food items from the fridge, you must clean the coils by following the subsequent straightforward steps:

One of the products that require frequent upkeep is the Square Glass Cake Display. It is a crucial component of every restaurant and food establishment. For more information on the appliance, go to the Simco website.

  • Find the coils behind a top or lower grate or on the fridge's rear wall.
  • Eliminate any gathered dust and debris from the rings and the surrounding region with an appliance brush.
  • Clear all the remaining residue by using a vacuum hose attachment.
  • Clean the accumulated grease by using a degreasing agent.
  • Replace the bottom or top grate or reposition the refrigerator before restoring power and replacing food items.

Doors Not Shutting Properly

When you find your commercial refrigerator not cold enough, check the doors to ensure they're closing correctly. A rubber gasket placed around the door furnishes a seal that expels the hot air and keeps the cold air inside the appliance. The hinges also ensure that the door is aligned correctly and closed completely. If the rubber gasket is ripped or torn, cold air can escape, and warm air can enter, creating a warmer internal temperature. Similarly, if the door joints are loose or broken, you will not be able to properly close the door, resulting in escaping of cool air. While you can tighten loose hinges to realign the doors, broken hinges correctly or a damaged gasket require replacement.

Thermostat is Defective

A refrigerator's thermostat checks the internal temperature, giving a signal to the control board to prompt the compressor when additional cooling is required. In addition, you must know about the ideal temperature of an industrial fridge. It's typically advised that the temperature for optimal cooling should remain at 38°F. If the thermostat isn't properly working, you will not get a precise temperature reading, leading to a lack of cool air generation when required. When you find that your industrial refrigeration unit is not chilling, you can check the thermostat using the following methods:

  • Ensure the thermostat isn't obstructed by food objects that could modify its temperature readings. Take out or differently place any products that may be too close to the commercial fridges ducts or thermostats that supply air.
  • If the thermostat isn't obstructed, check the fridge's internal temperature using a separate thermometer.
  • If the thermometer's temperature is not similar to the thermostat's reading, the thermostat may be defective and needs to be changed.

Faulty Compressor

If the above troubleshooting points do not solve your problem, you have to assume that the device compressor may be past its sell-by-date. The compressor is essential in the generation of cool air for the device, concentrating refrigerant before it penetrates the condenser coils. The fridge won't cool adequately if your compressor isn't properly functioning. In addition to your premium commercial equipment not chilling correctly, you may also discover that the compressor is continuously working or making more sounds than usual. In such scenarios, it is recommended to contact a specialist to verify and change the compressor as required.

The Problem of Condenser Fan

The fan inside the refrigerator needs to stay cool as the condenser coils and compressor frequently get warm from soaking the hot air pushed out of the interior components. When the fan isn't working correctly, it could lead to overheating the compressor and a subsequent rise in your fridge's internal temperature. The reason your condenser fan is not spinning is due to some obstruction by an unidentified object. However, if you find the fans' blades have no obstacles, you must hire a technician to restore their functionality by changing the fan motor. The specialist will untie the mounting screws holding the fan in place and install a new device after taking out the motor compartment.
