MY FAN DOESN'T WORK UNLESS I JUMP START IT BY SPINNING IT AND FLIPPING THE SWITCH TO THE ON POSITON. IT THEN WORKS FOR ONLY ABOUT 20 MINUTES AND I HAVE TO DO AGAIN AND AGAIN.
IS IT POSSIBLY THE FAN MOTOR? IF SO, HOW CAN I REPAIR IT MYSELF?
Some fan motors have a start capasitor, some have a run capasitor and some have both. if you take out the capasitors (normally in the junction box) take note of which wires go where and head to a refrigeration spare parts wholesalers they should be able to give you the right ones then replace them. this shouldnt cost any more than $20 if that doesnt work you will need to replace the motor.

Shut the power off to the unit, spin the fan blade to see if it spins freely. If it doesn't spin freely, (there appears to be a little drag when you spin it),the bearings are bad, if it does spin freely, then try moving the motor shaft from side to side if there’s any play in the shaft side to side then the bearings are worn and motor needs replaced. Then, check the capacitor, if it’s bulging even slightly, the capacitor is bad and needs replaced. Most of the time people replace the capacitor if motor seems ok. If capacitor is ok, turn power on to see if the motor is getting the proper voltage, if it is and not trying to run, then the windings are probably open, the motor's bad and needs replaced.
The fan on the outside unit is powered from it's 240 volt source. Check that the breaker for the outside unit is not tripped. Also, a contactor is inside the outer unit that starts the fan - it may be faulty.
