When The Refrigerator Noise Will Not Stop

All refrigerators are supposed to make noise when they're running. However, it should be a low hum operating in the background. So, if the noise becomes loud enough for you to hear, you might have a problem to resolve. Ideally, you should only hear the sound when in the same room. In most cases, these noises indicate that your commercial refrigeration appliance isn't working as it should and needs a replacement. Here are the reasons your appliance could be making noises. 

The Refrigeration Appliance Stands on an Uneven Ground

The first thing you should check when you notice excessive noise from your unit is whether it is standing on a level surface. Most models have adjustable legs that may fall out of alignment. This happens because the commercial refrigeration appliance may move as it runs, making the leg fall out of alignment. The best way to handle this is to adjust the legs.

However, if you aren't sure you can realign it, call the technician to assess and fix the issue. The lack of stability can also lead to the items inside sliding and touching the walls. As a result, this increases the noise intensity inside the appliance. The good news is, resolving the balance should restore normal humming. However, if the loud noise persists, some other component has a technical issue that needs repair.

You Need to Fix the Damage to the Fan Blades

It is also possible that your fan blade has incurred damage or is blocked. In such a case, standing close to your unit should help you determine this issue. Any noise from the vent between the freezer and the fresh food section indicates a fan could be blocked or damaged. If this is the case, note that the issue is complex compared to leveling the refrigerator. Hence, it is best to allow a professional to handle the repairs to avoid damaging your appliance.

The Tubes in the Condenser Coil Are Dirty

Another common reason your commercial refrigeration appliance might make endless noises is when the condenser coil tubes are touching. These stick at the back of the appliance, and their role is to dissipate the heat, which enables the appliance to cool down your food. So, if you have moved the unit recently, these coils are likely bent, leading to noise. Note that you must be careful when inspecting this part of the refrigerator. This is because any punctures could lead to leaking refrigerant. On the other hand, a technician can diagnose and resolve the issue without causing further damage to your appliance.

There are several other reasons why a commercial refrigeration unit could be making excessive noises. Talk to a commercial refrigeration repair expert when you notice the odd noises and have them resolve it for you. The sooner you find and fix the problem, the lower the chances are of a complete appliance breakdown.
