How electrically friendly are you? Do you have and know how to use an ohm meter? There is some basic checking on the windings you can do to see if you have short.
The fan motor on your year AC unit is buried inside the fan housing. To get to it out, you have to take almost everything out of the roof unit. And I mean right down to the metal tub of the bottom. The compressor unit has to come out to get the evaporator fan blade off. It is doubled ended armature shaft. One end has a fan blade outside to blow across the condenser. The the other end is inside the unit to blow across the evaporator.
You can see the fan motor here out in the open. That is not the problem though, the evaporator fan blade is the problem.
Here is the inside fan blade
You can see it here, behind the evaporator coil.
Your year unit will have a capacitor for the compressor and the fan. They have changed the ratings of the fan capacitor over the years.
When I bought my new fan motor, I had to change the capacitor
This was my original motor.
And the new one that replaced it
If you know 120 volt AC control wiring and DC control logic, you can trouble shoot these. If this is too much for where you are at, then a shop may be a need.
At the moment my compressor system died last week. Pending what the shop rate you would get charged to change out the fan motor, if that is it, it may be cheaper to change the AC unit. I think my fan motor was around $150 ish but I did all the labor. If your compressor unit is the issue, start with a new one.
Hope this helps and let us know what your skill level is.
