At the furnace remove the green wire on the G terminal. If the fan turns off when the heat cycle is finished then it is a thermostat wiring problem. NOTE also make sure the new thermostat is not set to fan on but to fan automatic.

Then the fan/limit control is defective or the fan relay is stuck/defective.

Model #? If the unit doesn't have one of these, the circuit board is the problem.
