I think that Jim could be right on target but, I am wondering did you replace the dryer and pull a vacuum on the system to remove all the moisture from the system before recharging?? I f you did not you could have a small amount of moisture in the system that will freeze in the expansion valve when operating stopping all flow of refrigerant. This will stop all cooling until the clog melts then work a while then stop again when it freezes again and so forth...Good Luck...Mark
