Loud buzzing noise

It will rattle slightly, this is normal. The ones that are burned out will sound like they have gravel in them, you can defininely tell something is wrong.
The problem with diagnosing Kenmore fridges with this problem is that there are different manufacturers. Yours is built by Frigidaire and probably has a Tecumseh compressor. We find more failed compressors with the Tecumsehs than we do with the models that have Embraco compressors. The models with Embraco's generally have more relay failures.

You should not hear the buzz/hum at startup. You will need to replace the compressor, which will be replaced at no charge to you if it is less than 5 yrs old.
If it is older than 5 yrs, you can have it replaced, but it will be almost as expensive as a new fridge. You can buy an aftermarket start device called a 3-in-1. This has a start capacitor built in to give it a little more boost on start up. I don't recommend using them unless it is a short term fix until the compressor can be replaced or if it is out of warranty and there is nothing to lose anyway.

with any luck this is you overload and relay
it is the plug on the actual compressor, this is very easy to replace, if you replace it and it does exactly the same thing its your internal relay and your compressor is done....

Testimonial: "thank you...I removed the relay/regulator to find it rattled and found burnt marks inside. I found them online, am waiting its arrival now."

Hi,
Without actually putting gauges on the system to see what is really going on, I would say that your compressor has failed. There is a good chance that it is something inside that has broken. Turning it off and back on will give it another life sometimes but like youexperienced it is usually short lived.
I assume that you have checked that the condenser fan is running underneath the fridge. Also that the condenser coils are not completely plugged with dirt. These things can also make your firdge od wierd things...
This should give you a couple of things to checkout, but I fear that the compressor is bad and you will need to replace it or get a new refrigerator. If you choose to replace the compressor get a full price quote before the work is done, as it may not be worth doing if you have an older refrigerator.

I hope that this helps you to solve your problem.

Thanks for using Fixya!!
