Do as you've done before, that's what I do. Drain and blow lines, then pump anti freeze through. Run water through door then leave pump on for a few hours until 2-3 cycles of ice have run through the ice maker. All is good! If your fridge has a filter that has to be in place for water to flow, they will usually remove he antifreeze coloring, mine did.
