Kenmore Refrigerator Knocking Noise

My Kenmore refrigerator has loud knocking noises coming from the compressor when starting or stopping. The compressor shakes. Something inside is hitting against the tank. At night it sounds like I'm sleeping in a blacksmith shop. Has the compressor failed internally, or do I just need to replace the four grommets?
Kenmore Model #253.64873400. Mfg. Nov. 2004. Top Freezer.

Thank you for your question. I can understand your concern about this knocking noise. The information you have received from Marc is very good. I can understand your concern about a noise coming from the refrigerator. Now, if the noise is occurring when the unit cuts off, the most likely cause will be the compressor. If this is a clunking noise, it will be from the compressor. This is a normal noise that can occur at any time and there is no fix for it. A compressor can make this type of noise at any time. It doesn't mean it's bad or is going bad. This is actually a normal noise. It may never make this noise but usually at some point it will. What's happening is, the mechanism inside the compressor, has gotten out of balance. The compressor will shake, due to the sudden drop in pressure, when it quits and the mechanism is hitting the frame now, making the clunking noise. It doesn't mean anything is going bad and normally it will only do this when the compressor quits but it can on start up also. I hope this helps you. If you would like more assistance, reply to this thread and I will be glad to assist you further. Thank you for using Manage My Life.

I found the answer! This solution has never been mentioned anywhere on the internet that I know of.
The manufacturer (Frigidaire, in this case) used only 3 compressor mounting screws in the 4 compressor mounting lugs. No wonder it was shaking! Sears wanted $5.00 plus $8.50 shipping for a single screw. I bought one at a local parts house for $4.11 and installed it today. No more knocking noise. I'm looking forward to a good night's sleep for a change.
Thanks for the replies to my question.

Arnell, this is a normal noise that the compressor can make, if it gets out of balance internally, as listed above. There is no fix for this and it does not mean there is a problem with the compressor or that the compressor is about to go out. I hope this will help you.

I have a Kenmore 65603 refrigerator freezer, and have a problem with water and ice accumulating in the frig section. I have increased the temperature setting, but this does not seem to help. Any suggestions?
