Commercial Refrigerator Repair

In this article, we will take you through an overview of the troubleshooting process that occurs when a commercial refrigerator is not cooling as it should. A commercial refrigerator repair professional who is competent and knowledgeable should look for these things when fixing a commercial refrigerator.

Let’s start with a brief description of how a commercial refrigerator works, and take a look at the main parts and their functions. Essentially, a compressor is used to pressurize and heat refrigerant, which is then cooled by a condenser. The condenser uses a fan to cool off coils. Then this condensed, but high pressure vapor is expanded in larger coils in an evaporator after passing through a metering device. Air is blown through these now cold coils containing low pressure vapor, to send cold air through the unit. The refrigerant ultimately makes its way back to the compressor to repeat the cycle. It is a simple process, but for the commercial refrigerator to work, there are underlying components and functionality that must be operating correctly.

The first thing a repair technician should take note of at the commercial refrigerator unit is the temperature. This helps shed light on what kinds of problems might be occurring with the refrigerator. Is the temperature too high? If so, is it just out of range or significantly too warm?

Next, all fans should be evaluated. Fan motors burn out in commercial refrigerators, and can have a significant impact on the operation of the unit. After looking for that, the repair service technician should check the coils to make sure they aren’t obstructed by ice, grease, dirt or other materials. When we do commercial refrigerator repair, we frequently find that neglected condenser coils are the source of the commercial refrigerator not cooling.

Is the compressor running? Sometimes the condenser unit will have problems starting or operating normally. This entails its own troubleshooting and diagnostic trajectory. The service technician will take note of whether the unit is running, and if it is not, whether it should be according to the temperature control. Assuming all of these tests indicate that the refrigerator is operating as it should, yet the temperature is still too high, the technician will turn to the refrigerant line for evaluation. At this point, there is a strong chance that the refrigerant pressure is off. If the refrigerant pressure is low across the board, the technician will adjust the level, a service commonly referred to as adding Freon to the commercial refrigerator. At the same time, it should be noted that there can be a restriction in the line, which would cause an abnormal pressure distribution line and affect the commercial refrigerator.

A repair technician has to evaluate many different parts of the unit as he tries to understand why a commercial refrigerator needs repair. Many problems have the same or similar ultimate outward symptoms, and a thorough evaluation is needed in order to diagnose the specific cause or causes of the problem. A professional commercial refrigerator repair company’s technicians will contrast the information about your unit against their experience and be able to repair your unit.
