At wits end. Machine stoped making ice. Service replaced evaporator and drier/filter. Made ice for two days and then all ice melted. He removed a part that controls the thickness of ice. He said that he has done that succesfully on many machines. He has been back twice, machine produces ice for a couple of days and then melts down. He now has replaced that part he took off, when he lleft he said that he doesn't think it will make any difference. The machine is now making ice, but will probably quit in 2 days again.

Any advice would be appreciated
