One more test that you want to try is locate the liquid line that runs from the condenser to the evaporator. Find an open metal spot near the middle and feel the temp of it before starting the system, then have someone turn the system on. You should feel it go from room temp to warm and remain that way. If if never goes warm or goes warm and then back to room temp, that confirms a blockage.
