This could be a problem with your digital thermostat. Check to see if the batteries are good or if they need to be replaced. Also check that the fan switch is on the correct setting.
The problem could also be due to a faulty fan switch, or with the circuit board of your furnace. These problems are a bit more complex because of the wiring involved and usually require the skills of a heating professional.
