Refrigerator noise

Does you compressor use a fan to cool down the condencer section or is there a coil on the back of the frig?
You can put a sound jacket over the compressor. Just make sure it is only over the compressor and does not block air flow if you have a fan assist condencer. If you have the coil on the back of the frig just cover the compressor and there is no air flow to worry about. You can use most anything you want. Try an old childs jacket. Do not block you drain pan either.

There is no way other than a sound blanket to lower the noise coming from a refrigerator. The compressor is a pump and makes noise as it runs and the hotter the air around it gets the louder it will get. Make sure it is on level ground also. This is what I do for a living trust me you cannot stop the noise no matter what you do short of remoting the compressor and condencer, very costly. Also with the new freons they seem to be getting louder especially when they startup.

BTW I meant the hood from a child’s winter coat. Unplug the refrigerator and place it over the compressor. Get some silver metal tape, tape it to the compressor or use straps and make sure it is snug but not overly tight. This is similar to the cover some people put on their water heaters to keep costs lower, just a lot smaller. Silver tape is heat resistant and should not peal off like duct or other types of tape will because of the heat from the compressor. You will be surprised at how well this works and it will not hurt the compressor either. I added one to my mother in-law’s outside a/c compressor because of a neighbor’s complaint of the noise level at night.

Blindjim is correct: there are only about 5 makers of residential refrigerators. Just the names are been changed to protect the innocent.
