1153E..old...are there any typical probs or tricks for this old fridge..Im in a rental unit and they avoid replacing...have had service in past for this...I think its just cleaning and setting...any suggestions? Indicators? what are the proper settings for this model..just have a freezer dial and a "fresh food wheel" what is the tiny hole from freezer into fridge with a tiny water catcher? Does this signal the frige or just collect drips of water? What about using warm or hot water in ice cube tray? Does this confuse the freezer temp because of condensation?
