Strange refrigerator sounds

Hello all...

So I'm having a strange problem that I can't seem to find an answer for even after searching the archives. I noticed recently that the compressor (condenser?) plate in my refrigerator appears to be making a strange sound. It sounds like there is water running through it (I realize it's refrigerant and has always been running through it, but I could never hear it before). It also seems to be working less efficiently and getting less cold. I haven't put a thermometer in there to be sure what the difference is but I noticed that the ice that typically freezes to the sides of the condenser is now slowly starting to melt. From what little I could glean through searching this might mean it's low on refrigerant or somehow air has gotten into the lines. Not sure but hoping someone here has had these symptoms and can help out. Compressor still comes on fine and it's still running, but worried that this means bad stuff down the line.

Anyway any help someone can give to narrow this down or confirm what I'm suspecting would be much appreciated.

Take care,
-Levin

Figured it out on my own. Turned out to be the cooling fan that ran over the compressor. I have an AB CU-100 air cooled unit so the fan is pretty important. At some point it must have burnt out and then caused the unit to run extremely hot which somehow was causing the running water noise through the evaporator plate inside the refrigerator itself. Wasn't really a hard job, fan was just a 120mm computer fan which I bought from a local electronics store and cost me all of $19. Easy to get out and rewire back up. Now seems to be running fine. Thought I would update this in case anyone in the future has a similar problem.

Take care,
