To repair a water leak at the water valve I pulled the refrigerator out, took off the cardboard cover at the bottom and removed the copper attachment cleaned it reassembled and tightened. While I was down there I used the vacuum to clean all the dust accumulation and got to close to the compressor fan while it was running. Now it rattles. I unplugged the refrigerator and cleaned the fan blades. I noticed there was a lot of in/out slop. It now has an unpleasant noise, more of a rumble than a rattle. I just wonder if it was damaged to the point where it will stop running correctly.

Thanks, It's funny went out for a while and now it seems normal. Hopefully there wont be anymore issues!
