hi lucas,

I'm sorry but when I read again the whole thread, I saw that the compressor you had is fine. it is not a LBP that you need but M/HBP is fine, which brings me back to your first problem. it was fine and than got hot.

if the compressor is the right cooling capacity, than the problem is else where and I suspect the cup tube.

I dont like them in a walkin freezer, cant adjust them.

I'd go for a TEV and keep the EN9213E.
