We all feel distracted anytime we enter our kitchen and notice some loud buzzing noise from our refrigerators. Generally, a refrigerator might produce noise for different reasons.

When there is a moderate noise from our refrigerator’s freezer portion, it is normal. However, when the buzzing is overly loud, signifies that your fridge need’s a service or repair. Without further ado, this article will help you to understand the effective techniques to stop your refrigerators from buzzing.

Steps to Stop a Refrigerator from Buzzing

Step 1 – Try and Listen to the Source of the Noise

Is this Buzzing coming from the bottom, back, or inside your refrigerator? Loud noise coming from your unit’s back might indicate the problem is with defrost timer, compressor, or condenser fan. If the fridges buzzing is rattling from the bottom, most probably, the drain pan is loose. If the noise is from inside the refrigerator, the evaporator fan might be the failing part, which circulates air through the fridge and freezer.

Step 2 – Clean the Entire Refrigerator Condenser Fan

The condenser fan is among the essential part of our refrigerators. This is the part that aids in keeping the condenser of our fridge cool. As the condenser fan is spinning constantly, it is used to suck up all dust especially for some individuals living in a dusty environment.

Therefore, the specks of the dust accumulated by this fan play a significant role in our fridge’s making loud noises. Use a vacuum cleaner to clean the condenser fan. Also, ensure you unplug the refrigerator before doing anything to avoid any injuries. Clean the fan and its surroundings using a clean cloth.

Step 3 – Look and Listen for Any Faulty Defrost Timer

If the Buzzing you hear has a scraping and ticking sound, the refrigerator defrost timer might be faulty. Therefore, check for any frost buildup in the fridge and freezer compartments. This indicates that the fridge timer is failing.

On the other hand, if the refrigerator is buzzing only twice or once per day for about one hour, this is another indication that defrosts timer must get replaced. In this case, you will require refrigerator repair experts to investigate further and do the repair.

Step 4 – Utilize Soundproof Floor Mats

The fridge can vibrate due to a faulty compressor and when its legs are not appropriately balanced. In such a case, the soundproof floor mats will hugely help to solve this issue. These mats are kind of dense, thick fabrics and with elastic construction.

Since one person cannot install the mat, look for a friend to help you. Lift your refrigerator gently and slide your soundproof mat under it. However, consider securing the mat using non-flammable glue or double-sided tape. Now, put your fridge down slowly.

Step 5 – Inspect if there are Loose Parts in the Refrigerator

Loose parts in your refrigerator might be the cause of a buzzing fridge. Since the fridge comes with many different parts, they may be both static and moving parts. And as the appliance ages, some parts might loosen, producing distracting noise.

First, inspect your refrigerator externally. In this case, watch out for any loose side panels and handles. Generally, examine the entire freezer stand for any cracks. Check for any loose drawers and trays inside the refrigerator. If you find any issue, call a professional to fix it.

Step 6 – Allow Appropriate Ventilation to Your Refrigerator

Lack of ventilation might be the cause of the refrigerator producing excessive noise. Generally, the refrigerator utilizes its surrounding air to keep its insides cools. Therefore, lack of ventilation will hinder the airflow of your fridge and also make it warm.

The fan inside any warm refrigerator works harder to keep it cool. As a result of a faster spinning fan, the appliance starts buzzing. Therefore, always try and keep your fridge in ventilated places. Also, ensure you keep a gap of about one inch between the refrigerator and the wall.

Step 7 – Consider Using Soundproof Panels

In many cases buzzing in refrigerators comes from its rear side. Especially for the individuals who keep their fridges against the wall. The sound waves from the rear of your appliance might bounce from this wall and spread through the house. This problem can be solved by a soundproof panel.

A soundproof panel is a product that absorbs unwanted noises. It stops the sound waves from bouncing from wall to wall since it is made with a soft, absorbent surface. When installing this product, you can use glue or double-sided tape.

Step 8 – Fill Your Refrigerator

Many of us might not believe this, but an empty fridge may produce a lot of noise than a fully stocked one. Modern fridges are manufactured to maintain the utmost efficiency, and they can still sense the number of stuff stored inside them.

Therefore, to maintain this maximum efficiency, the empty refrigerators will probably turn the compressor off and on. This specific action of the compressor is proved to produce a lot of noise. As a result, try and keep your appliance stocked with drinks, foods or fill it up by loading the water bottles instead.
