To stop your fridge from buzzing, remove all the beer and send it to an AA
You need to say where the buzzing seems to be coming from; the compressor,
under it, inside it, near the ice maker, near the timer (could be in back
or built into icemaker).
Some things like relays and small transformers can develop a buzz that does
not imply they are going to fail. Often this is a breakdown of the varnish
on the coils or metal plates which allows them to move in the AC field but
the part is otherwise functional. Try vacuuming all the dust out from
YOu can try pressing on the parts you suspect with a wood stick to see if
the sound changes.
I assume it still gets cold, do you have a frost problem too? Ice maker
Let us know if you can tell what is making the noise.
Still clueless, now get an applicance repair guy. Fridge still works fine
but just makes noise, wait for it to break and use the money for a louder TV
