Hello. We moved into a house a year ago that had a sub-zero fridge/freezer. When we go on vacation, the freezer unit sometimes shuts off (from not being used??). To get it working again, we have to turn the freezer up a notch. Consequently, we are now on notch 9 and don't have much room to go! Plus, our stuff is too frozen. But if we try to turn the level down a notch, the freezer shuts off. Or stops working, rather, since the freezer light still functions (and the fridge still fuctions). Another possibly related issue: the icemaker is really annoying and we have to turn it off so that it doesn't constantly overflow with ice. Thanks! Rebecca
