    superheat

    What application is this for? Ambient temps?I would lean towards an undercharged system or a restricted liquid line. What is the design freon and what freon is in the system?What are ur pressurers?

    Bad airflow?

    I am with Techman, a little more information would help tremendously!



    But a guess is a guess, check your airflow, bad capacitor on blower motor, bad bearing on small self contained, what ever would make your airflow inconsistant.

    Gotta add a third to that guess.

    I would start with airflow as well.  That is the normal culprit with erratic superheat.



    More info would help us narrow it down.
