    Have a Dynasys gen 2, About 4500 hours. It works great. My 1 problem is that once you start up the unit the ac takes a few hours to kick in!! But once it kicks in it’s super cold and will work until I move the truck……. Then the process starts all over again.

    I’ve changed the high pressure switch & the capacitor by the motor, same issue happened.



    ANY ADVICE???

    Fyi, ended up being low on freon.... like 2 0z!

    The dynasys gen 2 should have 31-32 oz of freon, not 28.

    Also if your in Joplin, MO... the apu shop Joplin APU, is great, fast & cheap! I would highly recommend.
