I have a GE outside unit model # 810AJ030-C (Air Handler is inside)
when unit is turned on from termostat, outside fan gives a humming noise. I can then turn the fan Blade and the fan contunues to turn until the set temp is reach. Each time it has to be manually started and it works well until the termostat automatically regulates to set temp.

Re: Fan only spin when It is manually turn blades.
That is a classic capacitor problem, It needs to be changed, a Tech should be able to do this relatively inexpensively. I'll explain how it;s done on the off chance that you can find a supply house that will sell one. Do all of this with electric off to unit. With a 5/16ths driver take out screws where the electric wires go in and remove panel, there will be a shiny silver container with wires coming out of it, make a diagram of which wires go to COM HERM FAN
The replacement has to be identical for example 370v 45uf 5uf. Don't accept one with different values than what's printed on it. Replace and Happy cooling!

You are referring to the air handler portion of AC. One of the fan blades is hitting something. Kill the power to all of ac and air handler and open up the air handler by removing the panel facing you exposing the fan. Manually turn the blade and look for the offender. Bend back into place, put back panel and tape up properly and turn all breakers back on.
Ir maybe just moving the fan motor itself slightly will do the trick. Whatever is easier and works will do.
Can you see the condition of the coil itself? If it is blocked this could be a cause for the frozen coils. Also, check the condition of the blades on the indoor fan. Dirt and dust accumulation on the blades reduces airflow.
Check for fan operation by turning the fan control at the thermostat to "on". If the fan blows, it works. If not, check a circuit breaker or fuse.
If the fan blows when forcing it on with the thermostat but not in automatic, check the fan control circuit in the air handler. Danger: high voltage, beware! There should be a system wiring diagram inside the air handler somewhere.
If you have a multimeter that tests "uf" or "mfd" that is microfarads. That will test the capacitor. Turn off power to unit, touch top of cap with insulated screwdriver across terminals to discharge and remove fan and common. MARK WHICH WIRES GO WHERE. Or if no mfds on multimeter, amps×2650÷volts=mfd. Amp draw on fan wire off of cap times 2650 divided by the volts between common and fan on the cap. If cap is good it's likely the motor.
Do you mean the air handler fan doesn't run but the outside part runs? If that is the problem, try turning the fan blade with a stick. If it turns freely, you have an electrical problem. It could be a relay, a bad motor winding, a bad capacitor, or a bad thermostat, among other things. If the fan won't turn, the motor needs to be replaced.
Hi, Could be a run capacitor on the fan motor. They usually swell up and or leak when they go bad. If not, the only real way to test them it with a specific capacitor tester. A new capacitor would be cheaper. Make sure that the outside unit is disconnected from power before opening it up, try to spin the fan blade by hand. If it doesn't spin freely it may need oiled if possible. See above solution. Your problem is the fan motor though so if this don't do it, It will have to be replaced. If this helps, Please rate my solution.
