What is wrong if you turn the thermostat to off but the furnace is still running?

When you say the furnace is still running, I take that to mean the fan and not the actual flame portion of the furnace. If this is correct, you either have a fan relay that is sticking closed or your tstat is bad. == == == == There may be a very slight time delay the the thermostat before turning off the furnace, but if you are sure that you have turned the thermostat off and the fire continues to burn, you have a serious problem. Have it checked out. The gas valve may be sticking in the open position. Regards
