A:AnswerProbably not. The listing would say if such an upgrade was available and what it would cost, as well as suggest professional installation for the option (the plumbing has to be installed to connect your water pipe to the unit).
A:AnswerA 90-degree open door would not add to the width of the unit, so no additional space would be required on that side. However, the crisper section needs more than a 90 degree open door (on the hinge side) in order to be opened more than a couple of inches.
A:AnswerNo. An ice maker is usually part of the door, so you would need to find a same size door with the same hinge (or an adapter for it) that has an ice maker part of it. Then you would need to retrofit a water line to the unit so that it could feed water to the ice maker, plus a storage space for the ice made. This latter means a separate unit for that outside of the refrigerator, or use all of the available freezer space. If you are or know an engineer who is handy with tools, have plenty of time, and don't mind something that looks like it was supposed to be Frankenstein's wife, maybe then.
