If you get it for free (from a trash pile/ dump) then why does it matter. Give it a go and if it dosn't work try again. Why pay if you don't need to.

If you really want to pay then just have a look on ebay. Although they look a lot more expensive on the US sites than UK.

If you find a fridge with the compressor still int it how do you remove the actual compressor unit.

How do you stop the oil from coming out? (is this right if you turn them upside down the don't work)??

How do you get the gas out safely?

and what do you need to add to the compressor unit to make it work safely and reliable?

Thanks jazzman

Alot of times when people throw out refrigerators, it is because they do not refrigerate anymore, so would this also mean that the compressor is junk as well??????

Sorry to hijack this thread but I've found a fridge compressor on the top of a shop roof ( its next to some flats) and id love to take it home but my dad is concerned about it still having freon or whatever its called still residing within the compressor even though all the connections and lines have been cut or removed. So I ask, Is it safe?

Well, it's possible there is some hanging in the tubes, but it's only a microscopic fraction of what was in it originally... freon turns from liquid to gas when decompressed. Also, it's not toxic in its normal gaseous state (Well, just don't inhale it :)).

If it's a newer model chances are it used some modern refrigerant since freon is being phased out.

keep it the right way up and it wont leak, if it does just top it up with mineral oil.

with a sharp pair of side cutters, freon isn't toxic but heaver than air so don't breath it in because you could suffocate if your not in a well ventilated place.

you need to put a pressure gauge and hose, a air filter on the suction side is a good idea too. I add about 5ml of oil every 2 weeks or so to make sure it full.

Yes I need them, because in high pressure, quick connections are difficult to disconnect and very loud if you did that. With a bleed valve, after the chamber is full, close the chamber valve, then open the bleed valve to let the rest of pressured air that are left in the compressor and fittings out, so you can disconnect it safely :)
