Does the fan on the outdoor condensing unit come on when the compressor does? If so, Is the condenser coil clean so that the airflow from the fan can remove heat from the condenser coil so the compressor won't overheat and trip the internal overload compressor protection circuit? If yes then is the indoor evaporator fan working properly? If yes are your filters clear and evaporator coil clear so that adequate air is flowing over the coil to prevent the compressor low pressure protection circuit from tripping? If so is the refrigerant charge on the system correct- either overcharged or undercharged can trip the compressor protection circuit. By now you should have come across an explanation for your compressor short cycling. If I had to guess I would bet on inadequate airflow over the condenser coil do to a faulty condenser fan motor either not turning at all or turning for a few minutes and then stopping when it overheats. This is likely caused by an unsealed replacment motor being used outdoors and water/rust has accumulated over the winter season and/or the capacitor is bad (in this case the motor may be turning slowly backwards) or just plain old worn out. I hope this helps get you to cold air sometime soon GL!

SOURCE: RUUD UBHA-14 J11SFJA air handler. The fan (blower) doesn?t runs

Absolutely, however, you want to properly diagnose the reason why the fan is not running. It could be a less expensive part than the fan motor itself.
First, check to see if you have the proper voltage going to the motor. I believe your motor requires 240volts ac. If you do not have 240 volts, you have a control problem.......either the thermostat is failing to close R & G or your blower relay may have failed to close the contacts necessary for your fan to operate.
If you have the voltage, then you want try spinning the blower wheel with your hand. Does it spin freely? Is the motor warm/hot? If so, turn everything off for an hour or so. As soon as your energize it, try spinning the motor with your hand again.....if it spins freely with no resistance and then starts running by itself, the problem is the run capacitor (approx $20.00 depending on where you purchase it from). If there is resistance when you try to spin it, the problem is most likely with the bearings and you will need to replace the motor.......if you have to replace the motor, go ahead and replace the capacitor also, making sure it is properly "matched" with your new motor.

I hope you find this to be very helpful to you, moving forward. :-)

SOURCE: air handler motor stopped working

Check the capacitor before you replace the motor. It's a common problem that's easily fixed. Make sure the fan rotates freely.

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.

Hello,,there is a way to comfirm that but you will need a meter that reads microfarads, after discharging the capacitor with a insulated screwdriver you simply put you meter leads to each terminal on the capacitor with tje meter set to microfarads, if the capacitor is good it should read the same microfarad reading thats printed on the capacitor, if not replace the capacitor.
