Has anyone ever had their thermostat give them problems? Ours has been changing to "heat" all by itself. It seems to happen within a few hours of us changing it back to "cool." This started just the other day and we haven't had anything happen like the electricity going out or anything. Maybe it is just the beginning of our thermostat going bad? I don't think it is the AC because it seems to run just fine once I put it back on "cool." I did a quick google search but didn't have much luck finding anyone with similar problems and frankly, I am too hot and bothered right now to search much more in depth. As usual, I turn to my smart FSU friends.
