My thermostat's fan will not turn off. Do you have any suggestions?

Hope I`m answering you right ,I`ve never seen a thermostat that has a fan. Thinking you mean the fan in your furnace/airhandler,, sounds like the programing of the tstat is set on fan instead of auto fan. Do you still have the tstat programing book that somes with tstat?

Yes, I meant the fan on the HVAC. The tstat is not the problem. It is set on AUTO. Also after I disconnected from the tstat from the wall, the fan is still on and won't shut off.

Thanks.
