Check your superheat and adjust txv if required.

Ice block on compressor means there is liquid flood back to the compressor mostly. Is there ice block on the evaporator as well? In that case, make sure that melts away (defrost the unit) as the ice on the evaporator coil will act as an insulator to absorve heat. If that doesnt solve the issue, I suggest that you install a suction accumulator just in case to prevent compressor failure.
