Ok, when taking apart ice maker to force restart - we noticed that chute going into icemaker had solid hunk frozen ice so we removed that. Also had a small frozen bit of ice where water line comes in top of refrigerator to ice maker. We cleared both of these out and put things back together, turned on the ice maker and its been working great for a couple weeks now. We also removed the back panel and cleaned our the defrost drain - it has all sorts of gunk in it. Also thawed freezer fully and squirted hot water into vents in the back of freezer to make sure nothing else was frozen. Once put back together - haven't had water going into bottom of freezer and freezing anymore. So it seems as both issues are fixed. Thank you much for your help once again!
