Hi Hernán, obviously you have an expansion in the condenser, for having an obstruction in the condenser itself, generally when this happens the problem is located approximately an inch before where the freezing begins, the welding may have penetrated too much or the condenser was already covered before the work you have done. Perhaps he thought that everything was in the filter and the capillary, and in fact it was the dense or clogged condenser. The capillary should take into account that, being thinner in its inner diameter, it should have a slightly shorter length, and you on the contrary lengthened it more. I recommend leaving it in only 3 meters maximum. Luck. S @ lu2 friovega63.
