furnace question???

[Mneugebauer00]

I set my furnace to 65. It blows out hot air and works just fine. But once it gets to 65, it just keeps turning on the exhaust for the furnace. I have a natural gas furnace. It will click on for 5 seconds, then off, wait 5 seconds back on, then off. It will keep on doing this. Anybody know what is causing this????

Could be the diferential on the stat is set too close or the heat anticipator is is set wrong.
