What is for you the reason why you suspect the TEV for ice-building up of the evaporator?
I can think right now of ten other reasons!

If it's a Danfoss, open it complete counter-clockwise and turn the spindle afterwards 3.5 turns clockwise again.

But then, what have you adjusted with turning on that spindle you think and what if your problem isn't solved (it will be not solved, that's for sure)

It's a lot more complicated then you think.

There lots of reason why it freezes.
Is it fully freezing? or is the fins just frosting up?
does it frost back?
