The Refrigeration Compressor is one of the main components of your refrigerator. The purpose of the compressor is to compress all the refrigerator gas used inside of the fridge. This process raises the pressure inside the fridge, and the temperature, which is released through a set of coils outside the fridge. If the compressor is not working in your fridge, the unit will fail to cool. Knowing the common problems of a compressor is a good way to learn basic troubleshooting when your fridge stops working.
The Compressor Fridge increases or decreases the temperature and pressure of any air vapor entering the refrigeration unit. The model of commercial refrigerator you are working on determines how large the compressor is, and where it is located. If the refrigerator you are working on is not keeping things cold, or you do not hear any running action, it is possible that the compressor is not working. Check the temperature of the compressor itself. If it is incredibly hot, then there may be a problem with it. Listen to hear whether it is running. If it is running, you may hear the sound of the compressor whirring hard, like a motor trying to start, then the sound cuts out. This means the compressor motor is faulty.
Fans
For almost any troubleshooting situation with a commercial refrigerator, you should check to make sure the fans of the fridge are working. Fans help regulate the temperature of components inside the refrigerator, so if they are faulty, the unit may run hot, or not run at all. As soon as you start working on the fridge, make sure the fans are running. If they are not, make sure the fans are clean and free of debris. Check to make sure that all the wiring going to the fans is in good working order, and that there is no visible wire damage. You can use a voltage-reading device to make sure the fans are receiving power. Also, make sure the fans are running in the correct direction, as specified in your operations manual. If the fans are not working on your fridge, it can cause the compressor and other components to work too hard, causing them to wear out early. Check the fans regularly for correct operation.
