When your business relies on freezers, coolers, and other refrigerated storage, you need to know how to diagnose a commercial fridge not cooling. Unfortunately, it is not always easy to figure out what is wrong. Many issues can cause your refrigerated storage machines to malfunction. With that in mind, the mechanical experts from Merit Mechanical Service want to provide you with information that can help you. We will review some ways to troubleshoot problems with your commercial fridges, coolers, freezers, and other refrigerated storage equipment.
This is one of the most straightforward ways to diagnose a commercial fridge not cooling. You want to make sure the power cord is not damaged and that it is fully plugged into the electrical out. If everything is okay there, then check the circuit breaker box to ensure there are no blown fuses or tripped circuit breakers. Finally, you should verify whether the power outlet is working correctly.
The thermostat is also another component that can cause a commercial fridge to fail to provide adequate cooling. First, check it to ensure that it is set to the desired temperature setting. Next, use an external thermometer to ensure that the thermostat is reading the correct temperature. Finally, you should replace the thermostat if you believe it is no longer working properly.
The next step in how to diagnose a commercial fridge not cooling is to check the condenser coils. Make sure they are not clogged with debris or dirt. They are located either at the rear of the commercial fridge or behind a grate in most cases. If they are dirty, then use a brush or a vacuum to remove dirt or debris causing the issue.
The evaporator fan is another part of the commercial fridge that can create cooling problems. Before you try to inspect the evaporator fan, make sure the unit is unplugged. Then, check around the evaporator coils and fan to see if there are blockages or accumulations of ice. If they are clear, move on to testing the fan. Start by manually trying to spin it yourself. It should spin without catching or resistance. If there are no problems there, plug the unit back in and listen for noises that indicate the fan is malfunctioning. Finally, you can use a multimeter if you are comfortable using one to test the voltage to make sure it is receiving power.
The next step in how to diagnose a commercial fridge not cooling is to check the heart of the refrigeration system – the compressor. It should not make noises such as buzzing, clicking, or whining. If it does make those sounds, it will likely need to be replaced or repaired. If not, then you should make sure that the compressor is not overheating or continuously running. Those are both signs that you need repair or replacement from a professional cooling service technician.
Many might overlook this step in the process of diagnosing issues with your commercial fridge. However, problems with vents or door seals will impact the ability of your refrigerated storage to provide proper temperature control. First, check the condition of the door gaskets. If they are missing, warped, or damaged, they are likely to allow cold air to escape from the unit. Next, make sure that there are no food items or debris blocking the vents inside the refrigerator.
Refrigerant leaks can lead to major system problems as well as causing health hazards. If you or employees are frequently suffering from nausea, dizziness, or headaches, those are signs that your commercial fridge may be leaking refrigerant. Due to safety laws and regulations, you need to use a certified HVAC technician to check whether there is a refrigerant issue. A qualified professional can provide the repairs or replenish the refrigerant as needed.
