Most likely failure is the start capacitor. Disconnect power to the machine or at least turn off the circuit breaker feeding it. Then pop off the hump looking covers on the motors. The capacitors inside are probably soldered in. If you can solder great, if not, is there room to butt splice in to the existing wires and have the covers fit back? Anyway, either take the old capacitors to a motor shop and buy new ones or pull the motor and take it to the motor shop and let them replace the caps. They're cheaper than a new motor. I would replace both since the quality is suspect anyway. If you disconnect the caps yourself, make sure you mark which goes where. If you plan on butt splicing, you may have to wheedle the motor shop into soldering on some pigtails.
