    Haha , 2 of the most basic tools. They are priceless.

    Most manufactures won’t tell you their design specs so the above is the preferred method.
    The primary function of the design engineer is to make things difficult for the fabricator and impossible for the serviceman.

    The LG info you posted indicates the NR58LAJG has a capacity with R134A of 607 Btuh at -10 Deg F SST at 60 hz. Using the Tecumseh cap tube selection I entered this capacity with 120 Deg F SCT, 36" heat exchange length and .026" ID cap tube. The calculated length of 88".

    I selected .026" ID simply because it results in a good length...not too short and not too long. If you want to size for a different ID just enter what I did and run it with the ID you want.

    I just scrapped an old captube at the junk yard and I got 1 penny for it. I can't remember where I got it from,but,it came from somewhere.What did your captube look like? I hope it wasn't yours!

    I think your at the point where you need to by a new fridge. Labour on this job alone outweighs the cost of replacement , especially if you are still trying to find the lost restrictor.
