So before my heat and a/c stopped working completely, it wouldn't turn off! I would have to adjust it whenever I feel too warm or cold. I would turn it from 0-4 but it just would not turn off! At times it would turn off for alittle bit but would just turn right back on.. This happen for a solid 2-3 weeks until... It won't turn on anymore!! Since it's getting cold up here in Maine I need my heat! I hear nothing when I try to turn it on... Help?
