Re: Frozen Shut
We used to be able to get one pound cans of R-12 for around 5.00$ US in the Bahamas. I haven't looked for at least 10 to 15 years, though, so I don't know if it is still available. I worked in aviation and we were at the very end of updating to 134 and others. I am still older than I care to be though.

Same but reverse idea as heating the case.
I used to hold a can of computer air duster upside down around the base of the cylinder until the engine would come loose, that is if the soaks and heat wouldn't do it first.
We had a full cylinder of R-22 up until a few years ago when our home air conditioner started to leak. We emptied the full cylinder just giving it boosts over a month or so until the compressor seals were leaking too much. We figured that the damn thing was old enough (1979 York) to just get it replaced. When the contractor came to replace the AC, he noticed the green cylinder that said R-22 on the side of it and asked if it was full as he would like to buy it from us. He also said "good luck getting anywhere near 35 years out of these new air conditioners, they just don't last as long as the old ones". Same goes for the fridge downstairs that was about 40 years old when it quit, we bought a new one and they said the new one should last about 8-10 years before we'll want to be a new one.

I was thinking of mentioning the same thing.
Re: Frozen Shut
Well fellas there are a lot of ways to free up "frozen" engines and I believe that most of them have been covered here. Those of us with extensive experience each have their own method.
I hope this thread has been helpful to the "newbs" among us. With that I'm going to exit and move on to other modeling threads.
