This problem just started tonight. When we came home we noticed the furnace running unusually long. I turned the thermostat down and it continued to run. I turned the thermostat all the way down to 50 degrees and it wont shut off. The only way to get it to shut off is to go to the fuse box and turn it off there. Then if you turn the breaker back on it kicks right back on. I was told there might be a reset button but I don't know where it would be or that the thermostat is bad. I'm really not much of a mechanical person so any help that could be provided would be greatly appreciated.

Hi,


Most likely a stuck sequencer.


Sequencer # 3110 - 3571 can be seen and ordered here by paging down :
