If your fan still blows but you are not getting any cooling, probability is that you lost either the start capacitor or the PTCR( motor starter).
The box holding these is under the shroud on the curb side held on with a couple of 5/16 hex screws.
You should test for capacitance ( micro farads) and continuity, or if burnt, a visual check will suffice.
