Best regards friends. I have a Samsung twin cooling nevecom I made a change of compressor but I committed the serious terror of not replacing filter. Charging all BN and lowering temperature at 11 degrees in the freezing part, the pressure gauge went empty and stopped cooling, I opened the pressure gauge and no refrigerant came out, I made a small hole in the compressor outlet and the refrigerant knob was capping the capillary now as that type of systems is uncovered since those systems believe that they have an expansion valve and no liquid would pass Thank you for your help. Thank you

If you have a capillary, you should not have an expansion valve. The capillary does not always come off, it is better to change it although you can try with gas 141b cleaning agent introducing it with a syringe and then sweeping with nitrogen. Of course you have to disconnect the compressor lines. Change filter and empty before gas
