Capacitor-start motors are typically used in compressors where the motor 
must start against a heavy load.  Blower service is quite the opposite.  
If you measure c. 130 -160 vac across the capacitor when the motor is 
running, you have a capacitor-run motor.

Something may be in the process of breaking down, Phil.  I would 
sustitute a similar capacitor to find out whether the RFI is coming from 
the capacitor or from the motor.  

-  good luck
