Hi Gary
A good post, should benefit alot of people.
I have this " pet " thing, that a large percentage of service tech's do no understand TEV superheat, let alone how to test and adjust. But then again I am old.
I have a fail proof test procedure that I stated years ago on this site, only works if designer was worth his salt.
Do you have a similar procedure.
What I use is good for pull-down performance or at design, but takes time.
