As I was watchingTV this morning I noticed that it was getting hotter and hotter in the house. I looked at the thermostat and it was not calling for heat, but it was still blowing very hot air. I turned the thermostat to the off position and it would not turn off. I tried cycling it through the AC hoping that it would work, which it did after about 15 minutes. After that I set the thermostat to off and about 10 minutes later the heat was blowing with the thermostat off. Once again it was already in the off position so I am completely confused. I have a Totalline electronic thermostat. I just pulled the unit from its base on the wall and that finally shut it off. I have the same thermostat upstairs and it is working just fine. This is the seond time in a week this has happened (it also occurred last Sunday, but has been fine since then until now). I really need some help. I am hoping to fix this problem myself to save some money.
