Typically a water curtain will need to be replaced because the plastic cracks or breaks. Because of the curtains proximity to the evaporator, the plastic is exposed to constant hot and cold, so replacement is normal after several years. A magnet should also be in place in the bottom right hand corner, which is used to satisfy the bin switch. This signals to the control board to either initiate a freeze cycle, terminate a harvest, or shut off on a full bin.
