How To Fix Commercial Refrigerator Making Loud Unfamiliar Noises

A refrigerator is one of the most important appliances in your restaurant. Not only do we need it to store our food products but to also keep things cool, especially during the summer season. Refrigerators are not cheap and over time like other electronic appliances will start to break-down. One of the telltale signs of a refrigerator about to break down is unfamiliar noises. While some of them will require minor repairs, others would need a commercial refrigerators repairs specialist. Therefore, in this blog, we are going to help you fix your refrigerator that is making loud unfamiliar noises.

Source Of The Noise

As with everything that makes a noise, the first thing you need to do is locate the source. Observe whether it is coming from the inside or outside. Refrigerators are not complex machines, they are quite simple and straightforward. Therefore, locating the source of the noise should not be a problem. Once you are able to locate the noise source, fixing it will be much easier.

Noise From Inside

If you observe that the noise is coming from the inside of the commercial refrigerator, it might be due to evaporator fans that have become defective. This is a normal occurrence and does not require too much time to fix. Furthermore, if you notice that the noise relates to chirping, squealing, or groaning, then it might be due to a faulty cooling fan.

To dig deeper, open the refrigerator and hold the fan switch down. If you notice that the sound increases while holding the switch down, it might be due to a bad fan motor. In such cases, you need to get the fan immediately fixed. It is responsible for optimum cooling.

Noise Coming From Outside

In most cases, noises originate from the outside of the commercial refrigerator. The reason being that this is the area where most moving parts are installed. If you hear a noise coming from the rear of the refrigerator, it might be that the condenser fan is showing signs of trouble. Sometimes, debris and dust can accumulate causing it to create certain noises. In addition to that, a bad refrigerator compressor will also create awkward noises. A rumbling or a purring noise indicates that the compressor has become defective.

Refrigerators tend to make grinding, knocking, or scraping noises as well. As there are two fans installed in every refrigerator, you need to find out which one is making the noise. Check the condenser fan as well as the evaporator fan. It might be that something is obstructing it.

Moreover, if the blades happen to be damaged, they will need to be replaced. While you are working on the condenser fan, make sure to clean the coils as well since it will help the refrigerator run smoothly.
