Question about Honeywell Programmable Thermostat Heater
Sounds like a relay sticking. Possibly in the thermostat or possibly the furnace relay at the furnace. The next time it happens, unplug the thermostat from the wall. If the furnace still runs then it's the furnace relay.
Hope that helps...

Our Honeywell thermostat is model RTH6300B. Now that the weather is getting hot, we decided to put the centeral air on. Hot air keeps blowing out. I called Honeywell several times thinking that we had fixed the problem. It still is blowing out hot air. Also, my husband checked the wires. Has anyone else had this problem? Any ideas what it could be?

Possible solution would be to push the reset button if you haven't already. I have had to do it twice on my dc90 in the last week.
If you look at the glass where you can see the combustion chamber, the glass is oval, follow the long axis of the oval toward the 'top' of the ignition chamber (my unit is laying down, with the blower on the west end and the combustion chamber on the east, as I am facing south). On top of the chamber are two protected spade clips. In between them is the reset. Make sure that the unit is off, press the button, and fire it back up.
