    I got into refrigeration from when I left school at 16 and got my qualification through college now time served for 7 years. as my dad is a refrigeration engineer he got me interested in the trade as he has been in the trade for nearly 40 years. I stumbled onto your channel today and really enjoy all the videos I have watched and now a subscriber. Keep those videos coming. Sincerely Adam from Scotland.

    I wish there was more of those still around .
    Them digital controls sure make things harder to troubleshoot , I mean , once you get to s bloody electronic board , what are you supposed to do ?
    It's like we're gonna have to become electronic engineers now , innit !

    Thanks so much! Took me some time to understand turning it down to make it come on because I was thinking when the temp goes down it cuts off. Finally I see, when you turn it down that's the temp you want the cooler to be and it shuts off (opens) when it gets there with a normally closed solenoid. Gosh, I can't believe that tripped me up. Smh.

    great video! thank you so much. In my small cooler, I have a thermostat, but in the condensing unit, I have a low pressure switch. How would I set the low pressure switch if I want to control the temp just with the thermostat in the box? thanks
