I would check the "G" wire at the Thermostat and make sure that it has a solid connection. The other end screws on to a terminal in the furnace. Check this connection as well. This green(G) wire is what activates the 120v relay on the circuit board. You can test this by turning the thermostat to the off position and then jumping the 24v R terminal with the 24v G terminal at the furnace. if the fan comes on then the problem is in the thermostat wire or the thermostat itself.

Hello, most likely the capacitor has failed and needs to be replaced. the capacitor is a small oval or round can with either two or three prongs on it. When a capacitor goes bad the motor has trouble starting.
