If you own a commercial refrigerator or freezer, you know it is no silent machine. Some sounds your commercial unit makes are perfectly normal, while others may indicate a problem. In this blog post, we’ll go through the various noises a commercial fridge or freezer can make and explain what these sounds could mean.
A humming noise is a common sound that commercial refrigerators and freezers make. It is typically the sound of the compressor running, which is the heart of the refrigeration system. The compressor is responsible for circulating refrigerant through the evaporator coil, which removes heat from the unit.
As long as the humming noise is steady and consistent, it is usually nothing to worry about. However, if the noise is irregular or sounds louder than usual, it could be a sign of a problem with the compressor, such as a failing motor or low refrigerant levels.
A buzzing noise is another typical sound that commercial refrigerators and freezers make. It is usually the sound of the evaporator fan motor running. The evaporator fan circulates air over the evaporator coil to remove heat and keep the temperature inside the unit consistent.
A buzzing noise from the evaporator fan motor is usually nothing to worry about, but if the noise is loud or irregular, it could be a sign of a failing motor or a loose fan blade.
A clicking noise is often heard when a compressor starts up or shuts down. This is because the compressor has an electric motor that starts and stops as the unit cycles on and off. A clicking noise can also be a sign of a problem with the compressor, such as a failing motor or electrical issue.
If the clicking noise is accompanied by other symptoms, such as the unit not cooling properly or the compressor running continuously, we recommend having a technician take a look.
A rattling noise can indicate that something is loose inside the unit. This could be a loose fan blade, a loose evaporator coil, or loose parts inside the compressor. It is crucial to identify the source of the noise and have it repaired as soon as possible to prevent further damage to the unit.
A hissing noise is a sign of a refrigerant leak. A damaged refrigerant line or a leaking compressor could cause this. It is important to have a refrigerant leak repaired as soon as possible, as low refrigerant levels can cause the unit to work harder and lead to further damage. A hissing noise could also be caused by a clogged filter drier or expansion valve, so it is best to have a professional diagnose and repair the problem.
A variety of issues, including a faulty fan motor, a worn or damaged belt, or a loose motor mount, can cause a squeaking noise. It is important to identify the source of the noise and have it repaired as soon as possible to prevent further damage to the unit. A squeaking noise can also be caused by a failing compressor or motor.
If you hear any unusual noises coming from your commercial refrigerator or freezer, it is vital to have it diagnosed and repaired by a professional technician. By addressing any problems early, you can prevent further damage to the unit and ensure it continues operating efficiently and reliably.
