Question for eric

I would have called you, but you were probably closed, so....

I have a Vendo 126 with cooling unit model VT25.

How did they fill this at the factory? I saw a 2 inch crimped/welded tube protruding from what I can only assume is the compressor, the large round deal set back in the machine, behind the coils and fan.

Is that where it was originally filled? If so, is that the best place to have a service valve installed?

Everything works and runs when plugged in and the temp dial is turned on, it just won't cool. It freezes up the capillary tube right before the upper unit coils, and no coolant goes beyond that. Consensus is that it is low on Freon. I have R-12, so I just need a way to get it in the system.

I'll try and help a little here. That is the factory fill tube on the compressor. On the deck Eric did for me the service valve is installed on this tube. Best to talk to him before cutting into the system though.

I'm not Eric, but I know what he will tell you. You have moisture in the freon turing to ice.

I'd heard that, also. Blowing or vacuuming out the system will be part of my service valve installation. I know I should probably just send the unit to Eric or Antiquities, but the shipping hassle makes me want to find someone local. I'm not into a restoration right now, I just want cold cokes.

You may also have a leak. If you are freezing down the cap tube itself, there may be a restriction, as Moon said, or its low. Pull the unit, do a complete, thorough cleaning and have a close inspection. You may be able spot some oil residue. If the unit is filthy, cleaning it will make a world of difference!
Post back and let us know.

P.S.  Creighton, great meeting you this past weekend. The pleasure was all ours, finally able to put a face with the voice. Next time you're in the area, give a shout!
