The support spring that hold the motor in place inside of compressor has failed so when the compressor stops the motor bangs off the inside of the steel shell of the compressor. the only resolution is to have the compressor replaced

My fridge knocks when running


Your fridge's compressor motor is suspended inside the compressor housing on three or four springs. These springs are designed to hold the motor load in a vertical position. Transporting a fridge on it's side can stretch or break these springs which can cause a shudder stop condition (the fridge makes a shuddering banging noise everytime the compressor stops and sometimes when it starts).

It's a good idea to let a fridge sit for a bit anytime it is moved. Over night won't hurt but an 8-10 hours is more than enough time some say less.


the internet consensus seems to be that you should limit the amount of time the unit is not upright. And as stated above, leave it upright at least overnight before starting it. Apparently damage can arise from mixing of lubricant and coolant, so damage is more likely in an older unit with worn seals.

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.

Compressor makes brief but loud rattling noise when it shuts off. Other than that the refrigerator is operating properly.


There are rubber shock mounts between the bottom of the compressor and the fridge frame, if any of these are worn it can cause that sound. Sometimes the condensate tray is what is actually making the noise; when the compressor powers down it vibrates and causes the metal tray to shake, maybe bumping the side and creating the noice. Pull the fridge off the wall and take the cover off the back of the fridge. Be careful, there's some voltage going through there. Locate the condenstae tray, shake it gently and see if it's loose. Give the compressor a gentle push and see if that makes the sound. Usually it's one of those two things and not an actual problem with the unit. When you touch the compressor, be careful, they can get pretty hot.

Knocking noise from condensor


neoprene washers sometimes go hard ergo sound travels and is amplified by box section (fridge/freezer)

Knocking/banging sound on compressor start up


Check the compressor mounts. They are usually springs mounted with rubber. If they are two loose the compessor wil hit some other metal part when starting up. Shakle it and see what it is hitting. Ajust accordingly.

Compressor makes a loud grumble an vibrates when it shuts off


There are springs inside the compressor that suspend the motor. When one or more of those springs break then the motor will knock against the casing when it shuts down and loses centrifuge motion. The compressor will continue to run up until the point the it beats itself to death, which could be next week of next year. There's no way to tell. The only solution is to replace the compressor.

Knocking/banging sound on compressor start up


I have a GE ZIS480D - side by side with compressor on top. It had an even tempo knockng sound coming from comprssor area. I asked my repair guy (at his shop) wat it could be. He shruggs and says "dont know, I'll have to come out and see it for $65." Just give me an idea of what it might be. He says "could be the timer or the motor knocking on something. I'll have to come out and take a look".. I'm a very highend custom homebuilder and have built hundreds of homes with every possible issue imaginable. When a repair guy says "dont know need to see it" it means I have no idea but by the time I leae your house I'll come up wih something. When something doesn't make mechanical sense I just pound on it or give it a good smack. I do it with my truck, my computer, my doors that stick and even sometimes my wife (kidding about the wife, she'd take me out in a heartbeat. Anway, I got up in the compressor ares and smacked it a couple times from every direction and sure enough it stopped knocking. I have been called a genius before but all I do is force into submission and it works. A good smack with the palm of your hand will not hurt the unit. Give it a shot
