Jeff, thanks so much for all the info. had a lot going on (major issues with internet and unable to get back online earlier) -- yeah the cable co doesnt like me now.
update on ice over..... up until 3 days ago, no ice at all on the botton of the freezer (or frozen running down slope of back wall).. GUESS what? today i noticed a small piece of ice at the front. weird thing is, that this past saturday, my boyfriend emptied the entire ice holder for our cooler, and then we have ice over on the bottom again???? any idea? thanks for the termistor chart, i will get that checked asap. but any chance our ice maker is an issue on top of the temp sensor? thanks again, Jen
