I have to assume that you are referring to the fan on the outside Condenser Unit? The most likely causes are either a burned out fan motor, or a blown Capacitor on the motor startup circuit.
number of things. you could have a bad condenser fan motor. bad contactor or a bad run cap for the condenser fan motor.

There is an electrical drawing on the motor that tells you how to wire it.

First isolate source of smoke- was it the fan motor, wires to it fried or a pinhole leak in radiator going through fan. If the motor is burned out because of bad bearings or whatever you will have to replace the unit.
It is due to pressure rising due to a bad condenser fan motor, bad capacitor, obstructing of airflowat the condenser, or a dirty condnser.
overheating of the c.motor and will turn to stop or burn the winding of the compressor motor due to over heating
No. The condenser fan is for the A/C(right side). The radiator fan is on the left.
You did not mention the kind of car. Check the fuses and relay to be sure you have power. Also you have a blower motor resistor and the fan motor. Grounds are just as important as the power source.
I just paid $620 to:1) have the condenser fan motor replaced2) have the run capacitor replaced3) fill 4+ lbs of freonAccording to the invoice the fan motor alone was $549. The service tech should be able to discount the freon if your having work done.
