Is my compressor damaged?

post #1 of 5
Thread Starter 
Got a used Little Devil case last week with a built in phase change unit, however since I got it the compressor has made some awful noises, I suspected that it had came off it's spindle and was hitting the compressor shell.

When I moved the case slightly to the side while it was running the compressor would run at normal noise levels and sound just like any other NL11F compressor I've ever had, I assumed it was just a bad mount in the case that was causing bad vibrations.

Today however I took the phase unit out of the case so that I could have some repair work carried out on it, I decided to ghetto rig the phase unit and it's still making noises which concern me.

The last NL11F I had I also ghetto rigged up on a food tray and it didn't make any bad sounds, it just sounded like an NL11F should sound.

This one is on a piece of arcyclic that's on a flat surface and noise it generates makes me cringe, I've made a video so you guys can see for yourself and give me some advice, when moving it side to side it does quiet down and stop giving me the impression that something has been knocked lose inside the compressor.

Any suggestions?

It sounds to me as if there may be a lack of oil in the comp. Unless a comp is fairly level and the right way up it can be prone to making odd noises anyway, that's why fridge manufactures advise leaving a fridge standing for 24 hours before switching it on. So leave it and don't move it for 24 hours and try it again.

I've Ohm'd out all the windings and they're all fine, also haven't got any continuity between the windings and shell...

Compressor has no start capacitor so I wonder if it's trying to start on the run winding?

Sounds like one or more of the suspension springs inside the compressor have become damaged or weak over time. Shipping damage is a common cause of this. The fix.. replace the compressor or.. quick temporary fix, do what you did in the video, mount it at a slight angle. That angle looked small enough as to not cause any problems with oil pickup. Keep the angle minimal.. under 5mm lift on the one side if possible.
