If your electician says there is power to the pump then I have to assume the issue is not with the controller. While a bad pump is likely it's also possible the wiring to the pump (in the well has failed). Either way you need to call a pump service company to check this out.
I have to assume that your electrician is familiar with capacitors and their function. but I suppose it's possible he isn't. It is possible that you could show voltage to the pump with a failed capacitor. In any case testing a capacitor can be extremely dangerous if you don't know how.
