Have I fried my controller?

I have an MDC2250 controller running a rover.  During startup after a rough terrain test, I had a short circuit fault.  I found that a couple of strands of wire had broken out of a soldered connection and shorted the motor terminal to ground.  After repairing, I now have a slight rhythmic ( 5 sec on/5 sec off) buzzing sound while drawing almost 2 amps.  The controller eventually gets to an overheat situation. 

Have I fried my controller?
