Ice dispenser in the door is apparently a huge risk factor for fridge failure. The ice making machinery either being in the non-frozen section, and/or having some mechanical components passing through the insulating door, makes it struggle. People love it, but bad idea.

The fridge that was in my house when I bought it (recently) has an ice maker fully contained in the freezer at the bottom, you have to open the freezer section fully to get at it. Apparently that can work fine.

Just some tips for the future :)
