Cavalier 72 - cooling issues
SodaShopNick:
I am having some cooling issues on a Cavalier 72 I have been working on. The issues seem to be similar to what Greg Long posted earlier this month, but I did not see a response and did not want to assume they were exactly the same (his topic: http://soda-machines.com/discussions/index.php/topic,22624.0.html ). Because the machine was in decent shape on the outside I decided to leave it original and only work on the inside. I tore it completely down, powder-coated the tub liner, disassembled the bottle stack and cleaned and repainted, replaced the bottle gate solenoid, replaced the wiring from the solenoid to the block, placed all rubber seals and installed a new wiring harness. For the refrigeration unit I actually brought it to a member I met on the discussion site and he made it look close to brand new. He found a leak in it, repaired the leak, recharged it, installed a 3 and 1, new thermostat and wiring harness. His work was completed several years ago while I worked on the rest of the inside.
A few weeks ago I put it all back together, but for some reason no matter what number I put the thermostat on the temperature remains around 40-41 degrees. The compressor does cycle, but again the temperature does not appear to be changing much at all. I did not try what Greg did and pulled the thermostat out of the tube. Either way none of the seals seem to be leaking and so I am at a loss as to what can be causing this. I thought maybe this was a cut-in cut-off issue that I could adjust, but there are no adjustment screws on the thermostat to adjust this.
Any thoughts on this would be greatly appreciated.

Here is a picture of the cooling unit:

So just disconnect the thermostat’s wiring connectors & wire them together with an insulated jumper, let the machine run & see how cold it will get.
This test will help determine if it’s a thermostat problem or something else.
SodaShopNick:
Thanks Johnnie. I will give that a try and see what happens.

You stated that you replaced the thermostat. Some stats are rated 40 degree's +......... while the one you need goes from 0 up to to 40, Try your old thermostat if you still have it.
