had a look at a copeland scroll compressor today on LT pack.
comp has desuperheater vapour injection.
solenoid coil for desuperheater energised when comp contactor pulls in and comp runs.

no liquid flooding back all other 6 comps ok and no evap coils iced up etc, the solenoid valve for desuperheater is not passing either all checked.

question......if the valves are passing in the comp could this cause the comp body to ice up.

has anyone come across this problem before?
