Vendo 63 running warm
:
First of all I apologize for any of my newbieness. Been visiting the site for a while but just got an old Vendo 63 on a trade for some web services.
Anyway, my problem is everything on the machine works great except that it runs warm. Now if I understand this correctly, the evaporator (on top) is supposed to generate the cold air while the compressor (down below) supposed to suck out the warm air and push out of the machine. Am I close on this?
Anyway, both parts run, but the evaporator is spitting out warm air (about 80 degrees I would think) and the compressor down below is spitting out very cold air out of the machine. Suffice it to say my sodas are pretty warm.
This guy had the machine running several years ago but had it under shelter on the side of his house for the last 3 years. There was A LOT of dust, junk, etc. inside the machine that I vacuumed out before plugging in.
Does anyone have any idea what might be causing the warm air issue?? I imagine it could be a number of things.
Any help for this newbie would be much appreciated. Thanks!!!

Hiya and welcome, well one of two things may be going on here, first thing I think of is your compressor has some stuck valves inside, OR somebody repaired the machine or replaced the compressor and or the evaporator assembly (before you got it) and brazed the darn lines bass-ackwards! (there have been RARE occasions when a compressor will start and run in reverse, but it's usally cause by miswiring of the start & run terminals)

Here's a basic diagram of a typical cooling system simular to you V63's follow the lines and compare to yours and let's see if we can figure out whats going on here!

Johnie thanks for your help!
I compared the wiring diagram you attached and it looks like everything is wired correctly.
Because there was a lot of dust in the evaperator assembly I could not get to with a normal shop vac I tried to lightly spray the area with a jet hose and it seemed like I got a lot of junk out. I tried to make sure not to get the motor or fan wet.
Anyway, I turned it back on again and it seems a little colder (maybe 70 instead of 80) but it might just be me not sure. I need to get a thermometer to put in there to be sure.
Any other help would be much appreciated! Thanks again.
UPDATE: I did find a thermometer and popped it in there. Sure enough its 70 degrees. It feels a little cooler than earlier today, but that just might be because its evening, not sure.
UPDATE 2: Had it running all night. This morning its up to 77 degrees now. So no change really. I added a picture below in case it helps at all, compressor is hard to see because its dark, but hopefully its of some help.

Well assuming the plumbing all ok and the compressor's running,then maybe all you'll need is a recharge of Freon (F12) and then check for leaks, you could also have a refrigeration tech. convert it over to a F12 replacement ( I like "hot-shot" it's a "drop-in" replacement & you don't have to monkey around with oil additives,etc.) he should put a vacuum pump on it & recover any remaining F12, then recharge the system with a replacement coolent (134A, hot-shot,etc.) & check for leaks assuming your compressor,s in good shape you'll be good to go, you might want to talk to Eric over at Global compressors , look in you local phone book under vending & contact some of them & explain you've got an older machine that needs service & see if they can help you on a local level too. let us know how it goes!
