OUT SIDE FAN DOES NOT START WHEN A/C UNIT COMES ON. tHE FAN WILL START IF YOU GIVE THE BLADE A SPIN MANUALLY.

replace the cap with the rating printed on the cap. You can test to see if the cap is bad by turning on the ac unit and take a screw driver and give the blade a spin if it comes on you need a cap.

The condenser fan in the back near the compressor comes on when the compressor comes on. The fan motor is the likely problem. It is easy to replace and inexpensive. Here is a link that should help Condenser fan replacement Spin the fan blade by hand or listen closely when it is making the noise to isolate it.

Now if the fan is not the problem and the noise is coming from the compressor, the compressor will likely need to be replaced. This is hardly ever worth the cost of the repair. You would be better off buying a new unit.

look on the side of the motor it will have a wiring diagram your fan supplies voltage to the capacitor its self so two of your wires go to the capacitor not just one. good luck

If you can start it by turning it manually, and it starts, then the only obvious solution is replacing the motor, since it's obvious power is getting to the motor, and if so should start on it's own.

If the fan does not spin and the motor hums, you have a stuck rotor. It may be due to bushing/bearing alignment problem or a lubrication problem.
Try to spin the fan blade manually. It should turn freely, otherwise the rotor is stuck. Remove fan blade and put few drops of lubricating oil on the bushings/bearings and manually turn the shaft to free it up. Alignment of shaft and bushings/bearings must be after lubrication is done and the rotor is still stuck. Move the shaft up and down and side to side until it smoothly spin when manually turned.

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.

your capacitor on the fan side is blown but that particular model needs a dual capacitor. Don't run the fan too long like that you will overheat the windings and melt her down.

Replace the fan motor capacitor. If that does not correct the problem you will have to replace the fan motor.

If you have power to the fan and the fan won't come on, then its bad. You don't have to do another check. You will know if the capacitor is bad by turning the power on to the unit and taking a stick to start the fan. If the fan starts running after manually spinning, then the cap is bad. If not, the motor is bad.

Unplug your unit and check the fan blade by manually rotating it with your finger it should rotate freely, check if the blade is not touching the fan blade frame,Check for worn out fan motor bearing. Check if the screws are not loose.
