    You said it's pumping down but failed to say what the low pressure control is set at.

    If jp had a dollar for every time he's linked that sporlan headmaster charging document.....you'd be able to retire!

    On a more serious note, sounds like its time for you to put your cold weather gear on and take some superheat readings after topping the charge off....

    I've learned probably more from him than any of the guys I work with, honestly. 2sac, icemeister, phase loss, and cracker too just to an,e a few more who are awesome.

    Thanks, guys. You're making me blush.

    gcmechanical,

    I'll answer any question that you've got here on the forums.


    Yes, low charge will cause uneven frost patterns as well.

    Thanks.

    Now, 2sac makes a good point, too.

    Take a few extra minutes and verify the settings of all of the operating controls.

    I took that to mean that it was shutting down on low pressure jp.

    2sac always makes good points, how could you go wrong with a guy who has Al Bundy as an avatar??? That makes me laugh every time I see it.
