what is the reason, how to fix it?

A new refrig­er­a­tor of the lat­est brand, which has a low degree of noise, began to buzz loud­ly, and this def­i­nite­ly cre­ates dis­com­fort. The ques­tion imme­di­ate­ly aris­es, why is it mak­ing noise — is it brand new and is it still under war­ran­ty? How to be in such a sit­u­a­tion? After all, only a faulty or dis­con­nect­ed refrig­er­a­tor does not make sounds.

Features of the location of the refrigerator

It is pos­si­ble that the refrig­er­a­tor makes a lot of noise dur­ing oper­a­tion due to the wrong loca­tion in the kitchen. First you need to find out why the noise occurs. The main source of noise from the refrig­er­a­tor is the com­pres­sor. He pumps cold tem­per­a­ture, and it is he who makes a loud noise, buzzes and rum­bles. If it is equipped with two com­pres­sors, then the noise lev­el is dou­bled, since each of the com­pres­sors will oper­ate at dif­fer­ent times in a relaxed mode.

In the case of a ser­vice­able refrig­er­a­tion unit, the noise lev­el of the com­pres­sor is quite tol­er­a­ble, here you will only need to put up with it. If the refrig­er­a­tor not only makes a lot of noise, but also makes irreg­u­lar rat­tling sounds, then the prob­lem lies in anoth­er rea­son, which is quite solv­able. First you will need to check if your refrig­er­a­tor is close to a wall or fur­ni­ture. In addi­tion, the vibra­tion of the device can usu­al­ly occur due to near­by objects. Make sure the refrig­er­a­tor is installed cor­rect­ly. If nec­es­sary, adjust the legs.

As for the cam­era, inside the cam­era you need to put things in order. If the refrig­er­a­tor began to buzz very loud­ly and the sound of rat­tling and ring­ing dish­es is observed, then the expla­na­tion lies in the prod­ucts that fit snug­ly against the walls. In par­tic­u­lar, we are talk­ing about glass jars and dish­es with met­al lids.

It is worth not­ing that before buy­ing a new refrig­er­a­tion unit, it is rec­om­mend­ed to check it before turn­ing it on so that the com­pres­sor pipes do not come into con­tact. Oth­er­wise, there will be extra noise.

Why the refrigerator began to buzz loudly: causes of malfunction

• Bad shock absorbers. If ear­li­er the new unit worked well, and then it began to make noise, you need to look at the com­pres­sor shock absorbers. If they are not firm­ly fixed, sec­ondary noise will occur. There­fore, there is noth­ing to be sur­prised that the unit began to rat­tle and “bounce”. Replace the faulty com­pres­sor shock absorbers with a new one and then the prob­lem will be solved.
• Coolant. A house­hold appli­ance using refrig­er­ant may start to make a lot of noise due to the gas cir­cu­lat­ing in the tubes with fran­tic move­ment. There is noth­ing wrong here, it’s nor­mal. I’ll have to get used to the hum­ming of the refrig­er­a­tor. See also: How to fill the refrig­er­a­tor with fre­on at home.
• No Frost. Unit cham­bers equipped with No Frost may encounter noise gen­er­at­ed by the rota­tion of the installed fan. If the device sud­den­ly began to buzz strong­ly dur­ing oper­a­tion, then this is due to ice that has frozen near the blades. Here, the sal­va­tion will be the com­plete defrost­ing of the refrig­er­a­tor, which will take at least 10 hours.

Noisy new fridge

Accord­ing to GOST stan­dards, the per­mis­si­ble noise lev­el of a refrig­er­a­tor is up to 55 dB and this is an aver­age sound. How­ev­er, if you look at the attached man­u­fac­tur­er’s instruc­tions, most of the lat­est batch­es have it around 40 dB.

Note that when choos­ing a tech­nique, you need to pay atten­tion to the label on the front side of the device. You will see the ener­gy con­sump­tion class, the vol­umes of each cham­ber and the deci­bel read­ing. If you want a refrig­er­a­tor that works almost silent­ly, ana­lyze the mod­els and pur­chase the one that has the low­est noise read­ings.

And if, when choos­ing a qui­et unit, it still emits a strong hum? We do the fol­low­ing:

• check the removal of the ship­ping bolts. They fix the springs where the com­pres­sor is fixed. If you do not pull out the bolts, then the refrig­er­a­tor will rat­tle and make a loud noise.
• let the refrig­er­a­tor sit for a while. Let it freeze a lit­tle — it will take a week for the device to return to nor­mal func­tion­ing.
• third — check whether the device is installed cor­rect­ly. Maybe there is con­tact with objects or near­by fur­ni­ture? For nor­mal oper­a­tion, it is required to leave a space to the wall of about 5 cm.
• pay atten­tion to the load of the refrig­er­a­tor. By the way, this applies to new and old refrig­er­a­tion units. It is quite pos­si­ble that pots or jars are in con­tact with each oth­er inside — this cre­ates a ring­ing. Here you just need to cor­rect­ly dis­trib­ute the con­tents on the shelves.
• Have you noticed that the hum of the refrig­er­a­tor is only at the begin­ning of the com­pres­sor oper­a­tion? This is nor­mal! At the begin­ning of the start-up, the motor needs a large start­ing cur­rent, which is why you hear the short-term growl of the refrig­er­a­tor.

But if every­thing is per­fect in your refrig­er­a­tor and it has been work­ing prop­er­ly for more than one year, and there were no extra­ne­ous nois­es before, this indi­cates a prob­lem. There­fore, he gives you such a sig­nal that some­thing is wrong with him.

General recommendations

Top­i­cal answers to the prob­lem of refrig­er­a­tor noise were con­sid­ered. If you have not been able to fix the prob­lem your­self, then you will need to con­tact a qual­i­fied spe­cial­ist. Most like­ly the sit­u­a­tion is in a seri­ous break­down of the com­pres­sor.

Impor­tant:

Some sounds, such as crack­ling with clicks, as well as increased buzzing when the device is turned on, are com­mon and do not por­tend dan­ger. Remem­ber that when buy­ing, you need to study the tech­ni­cal prop­er­ties of the refrig­er­a­tor — this way you will avoid noise.
