The motor may be bad, but it's more likely your problem lies in the other electronic components. First I would check the wiring. After that, the capacitors mentioned are probably the most likely problem, so I would start there before worrying about transistors, then resistors, etc. The motor would probably be the last thing I checked. You can also test the motor by carefully applying a (low) voltage.
Most components on the board can be replaced by someone with skill. If a part no longer exists, something surely can be substituted, though fitting it all in the casing may present a problem.
