Working on a HP system.
It was making ice in the evap.
84 deg ambient
a real low suction pressure, a normal for ambient discharge pressure.
19 degree SH.
Checked the TEV, the bulb was hanging in the air.
Restrapped it to the suction line ( screw tightend mount was still attached to suction line inside the evap case).
Suction and discharge pressures the same as before, now with 30 deg superheat?????????????
Attempted to adjust TEV, found turned almost all the way clockwise (perhaps 1/16 of a cw turn remaining)
Couldn't get any change to SH.
Has the TEV bulb lost charge or did a previous tech screw things up?
I think either way time the change the TEV, lucky it's a flare fitting.
Any other ideas?
