Default AC

I have a 2003 conquest motorhome with a duo therm AC. When i turn on the ac it hums and sounds like a motor is locked up.
Any ideas of what it could be would be appreciated

My first load in the parts cannon would be the compressor start capacitor. These give the compressor an extra boost to get started. If they are bad the motor usually just groans until the breaker kicks.
