I got home from vacation and my refrigerator is not working. There is water, but no ice is being made. The freezer appears to be working, but the refrigerator section appears not to be working.I searched, and have ordered the repair manual. I was wondering if anyone had any ideas of what the problem could be?Any help is appreciated, since I can't seem to get a response from our usual repair man, and we are VERY rural, so I may have to repair this myself if possible.Thanks!This is model FRS26ZRGB4.
