Question about Refrigerators

1 Answer

I have a knocking (5 quick, loud knocks) sound intermittently on my refrigerator. I think it is when the compressor starts up (not 100% sure). I opened the back panel and everything looked normal except there is some black, sticky tar-like substance on the side of the compressor, as if something is melting. It is on the outside of the compressor casing, but not dripping onto the floor panel. The fridge is a 4.5 year old Samsung side-by-side. The noise is loud enough to wake us up at night. Do we call a repair guy or is there some trick I can try? The compressor seems properly mounted on four springs. Fan is clean. I can't see anything abnormal with the coils.

Chances are that black tar like substance you are seeing if from the capacitor. This is were I would start, as a capacitor is not all that expensive. Make sure it is the same rating as the current capacitor, and be aware that capacitors store electricity. When you disconnect the leads don't cross the terminals with your fingers, or you will get a shock. Hope this helps

My KSRP25FNSS makes a strange knocking noise at each compressor shut down and sometimes during running. The noise is always a series of 5 knocks, very loud, in quick succession that telegraphs though


Hi,

By you discription above it sounds like one of the three spring the supports the compressor pump has failed or broke. Now the only fix is to have the compressor replaced, but if the unit is still cooling, currently its a noise problem only. I hope this helps you. If this is still under a warranty, ask for it to be checked as if in warranty it needs to be replaced. Good Luck

How do I stop the loud knocking noises coming from my refridgerator?


Pull the fridge away from the wall and inspect the compressor. Your description sounds like the compressor is hitting something. It is rubber mounted and usually can be pushed away from whatever it is hitting.You do not want to jamb something to stop the noise, as the compressor needs to move freely. Many compressors shake during start up and shutdown, and this is considered normal. Abnormal if the compressor hits something during this movement.

Knocking sounds like something is knocking on the door


Hi

The knocking could be the damper if it last for about 5 seconds when the compressor turns on or off, or it can also be the refrigerant gassing off in the evaporator this sound can be really intermittent, but is normal with the refrigerants used today. However the compressor you see is actually the outer shell, inside of which is a refrigerant pump (i.e.: compressor) which is on internal support springs. When the unit turns off, the momentum of the internal parts can sometimes knock against the outside of the compressor case. The only "fix" would be a new compressor. However this does not actually indicates compressor failure and most likely will run many more years with no problem.

Please get back to us if you have further query else please accept the suggestion.

"you are right that cleaning under your refrig wont get rid of a "compressor knocking" sound. what it might do is to lower the amount of heat from the condenser coils and thus cause less pressure and stress on the compressor making it run easier and less likely to bang or knock when shutting off.
if your coils were very plugged with lint and you have cleaned them, that will help but it wont "fix" the problem.
inside the compressor is a motor and a pump, the motor is supported by 3 springs and they can stretch or break causing the motor to hit one side of the black outer can and cause the noise.
that may be too technical, but its not something that can be repaired without replacing the compressor, at a cost of 700-800 bucks. most would not pay this as its not worth putting that amount of money into an older refrig."

"think that you are hearing either a freon related sound or even just the sounds of the unit going thru defrost.
how often do you hear the noise? just maybe once a day or is it everytime the unit shuts off?
either way i would rule out the ice maker and water system as when the "shut off arm" is up then it is off and wont make any noise, or ice.
keep the i/m arm up and then listen for the next day or two and try to narrow down when it makes the noise and frequency you hear it and then get back to me.
it may not even be a problem, just normal operating sounds that cant be changed."

Noise after the motor starts


Is this a clicking or a knock/pop sound? The knock knock sound can sometimes be helped a little bit by tilting the refrigerant filter drier (located in the compressor compartment) to a horizontal position. Ask your technician to do this for you.

Refrigerator has loud knocking sound when cycling down every 17 min.


could be the compressor.somtimes when they age you will hear a knocking or shaking sound.

If this is a new unit, by new i mean 5 yrs or less.It may need to be serviced.

Also cycling every 17 min is not a good sign.Could be overworking.Or low on freon. Bad start capacitor possibly.

Car started noise like nock ing that was from Clutch in AC copmressor


It could be the compressor is going out, or the clutch itself is worn out. If the AC still gets cold, then it is the clutch.

My amana refrigerator is making a knocking type noise


hi,

The knocking could be the damper if it last for about 5 seconds when the compressor turns on or off, or it can also be the refrigerant gassing off in the evaporator this sound can be really intermittent, but is normal with the refrigerants used today. there is a page in the owners manual devoted to noises your refrigerator can make.
