the answer to your problem is most likely the motor start capacitor. A AC motor can run in both directions. The start capacitor is used to cause the current to lag behined the voltage which determines the direction the motor will turn. Its posible the start and run capacitors are in one can. so changing one will change the other. However look for a wiring diagram. Do not asume that both capacitors are wired in properly. They may be fighting one another causeing premature failure.

Air mover is too close to the vents - the ductwork (re-routed 180 and back) must be modified or lined inside with a sound absorbing material.

check for Freon level if its low compressor will not run

Replace the run capacitor. It is a silver cylindrical object located in the electical compartment of you outside unit. There is most likely three places on the top where different color wires are attached. One is marked F,or Fan. The center should be marked C, or Common, and the last should be marked Herm, with wiring to the compressor. Make sure you write down or label each wire you remove and it's correct location. They must be installed on the new part just like they were on the defective part. For you to know which dual run capacitor you need, the old one will have printed on the side either 370, or 440 v,as in volts. You must also need to know the microfarad rating and it is also printed on the side with the voltage rating. Since this is most likely a dual(runs fan and compressor) you should see two ratings abbreviated as mfd. Something like a 5mfd for the fan motor and perhaps a 35 mfd for the compressor. CAUTION !!! This device has line voltage and you must insure the power is off at the disconnect/ breaker BEFORE you begin the repair. Sounds complicated but really only takes a few minutes. The main thing is getting the right mfd and voltage ratings for the new part and keeping a record of where the wires were mounted on the old one, and putting them back the same place on the new part.

sounds like a motor issue check for loose bolts on top of the unit i would get the unit cleaned and have the technician look at it
