I attended a call to a pack where I found the ICMT valve was stuck in the closed position.
The ICAD was saying the valve was open 83% but the valve was completely shut and pack off on HP.
Vented off the gas cooler and removed the valve found the valve not turning but the ICAD was ok.
Replaced the valve and the ICMT is now operating ok after a while found the valve moved freely seemed to defrost.
Found like a sticky substance inside the valve possibly oil has anyone come across this before.

Thanks
