Thanks for taking the time to make this video. I just bought a v21 and am having some trouble shooting problems. While this did not address the issues I'm having, I wanted to say I appreciate it

It has an electronic control which is set through the computer. Unless you are having a problem with your compressor or a leak there should be no need to adjust the temperature.

I have been offered an abandoned gently used Vendo V-71. what price range should I consider paying.

i notice that it doesnt come with a cold control.. how to set it
