    Sorry snap I must have overlooked that part.

    Tempco.. After ur boss learns his lesson you can take him out of timeout. Jk!!

    I will assume you checked the sight glass b4 pumping system down and it was full, not bubbling which may indicate a low charge.

    If you are still having same issues and confident charge is ok, I would suggest pumping system down, checking screen or other possible restrictions. If you find no evidence of restriction then I would replace txv and lld. Leak test, vacuum and then see where you are.

    Someone more experienced please correct me if I gave bad advice as I am still very new in the saddle

    Good luck tempco

    have you done a stall test on the fan in the end that is freezing? ive had this before, where everytime ive opend the case the fan is spinning, but after a few checks over a week i found the fan could be stoped with my screwdriver, after watching it over an hour i found the fan would slow down and sometimes stop, then speed up again.

    replaced the fan havent been back for that case since.

Stat has been acting erratic for awhile so we decided to change it. Boss said no at this time to checking screen. My guts with you chappa on the screen. Guess we will see what happens
    Thats crazy, I would check the screen on txv.

    If we suspect a restriction we are changing the TXV. It's sweat no flare

    IMO, this is a big waste of time, effort and money.

    In refrigeration, the TEV is considered to be a serviceable part.

    Take it apart, clean it, service it (replace a power element if needed)

    Full on replacement is really only required if the body is leaking or there is damage to the internal components.

    Yes I did in post #24. And JP if you remove the TXV and service it and even change power head why not just replace it? For the cost of time to sweat it out ( even better if they are flare), re- install, vacuum, etc and just a couple hundred more to replace. I've replace a few that had leaks in the body already in my short career.

    Which is why the word 'hardly' was chosen instead of 'not'. ;-)
