Sounds like a fan caught. Empty and defrost fully, then restart and check all working

Is it buzzing from the bottom rear of the unit?

try cleaning vents/drain holes in whole unit this should allow more air to flow.also when did you last manually defrost whole unit.....

Something has stopped your compressor. The part could be the start relay, start capacitor, overload or the defrost control board. where are the buzzing sounds coming from ? Sea Breeze

I believe that your refrigerator may need a new 12002495 or 1184282 Adaptive Defrost Control You can find it inside the fresh food section and behind the controls for temperature. Not sure about the buzzing sound yet but the moisture and thawing of the frozen food points to a defrost problem. Need you to unplug and have a look at the adaptive defrost control. Would not hurt to open the back panel in the rear of freezer and defrost if needed and need someone to check the defrost heater and defrost thermostat. Sea Breeze

I had the same problem. I found the buzzing noise was caused by ice build up around the fan motor inside the freezer. I believe water must have leaked down around the fan during a defrost cycle. I removed the ice maker, the ice cube bin and ice dispenser auger motor. It sounds complicated, but it isn't too bad. The ice maker and auger are connected with quick connect plugs. So just unplug, remove the screws and remove them from the freezer. You will need to remove several other screws as well, I believe 11 in total as well as the top freezer rack. This will give you access to the white aluminum panel that runs from the top of the freezer to about halfway down the back of the freezer. After you remove the aluminum panel you will see the fan about half way down the freezer. I found a lot of ice around my fan. The fan blades were hitting the ice causing the buzz. Remove the ice and the buzzing is gone. It took me an hour to complete this repair. I hope this helps.

it should come back after about 20 mins only and should cool back after about 10 mins.

i'm afraid the buzzing sound could be coming from your compressor which can not start. the over current relay is tripping off after 20 seconds to prevent the compressor from burning up.
i suggest to unplug the ref, let it cool for 1 day, re plug it after a day and observe the compressor if would run.

if the buzzing sound is still there and the unit is no longer cooling, then the compressor is not running.
check the relay of the compressor. it could just be the relay.

tnx 4 using fixya,

It sure sounds like a compressor problem to me. The buzzing sound is the compressor trying to start followed by a click which would be the overload protector tripping.

I THINK THE BUZZING IS THE COMPRESSOR TRYING TO START,ALSO LOOK ON THE BACK OF FREEZER AND SEE IF THE WALL HAS FROST ON IT,IF IT DOES YOU HAVE A BAD DEFROST HEATER OR TERMINATOR OR IT IS STUCK IN DEFROST,LET ME KNOW WHAT YOU KIND,ALSO YOU SHOULD UNPLUG IF YOU FIND THE COMPRESSOR IS TRYING TO START BUT WILL NOT,PULL OUT FRIG. AND SEE IF YOU HEAR THE CLICKING SOUND,ALSO PUT HAND ON COMP. TO FEEL IF RUNNING,BECAREFUL MIGHT BE HOT
