I am not sure if this is the right place to ask a motor problem, so advise me if not.
I have a water well with a vertically mounted 1.5 hp motor on top (jet pump). The motor was replaced a year ago at the cabin, so being where it is, it is not used very much. In a visit, I found that the pump was not working. For full disclosure, I will let you know that the circuit breaker is along the coast so corrosion is common, and I found that only one wire of the 240v was active. When I flipped the breaker off and on, both were active. However when power is switched on at the pump, the motor only hums. I removed it from the well and determined that the shaft turns freely, but again it only hums when power is supplied even with no load.
I understand that this type of motor is also commonly used on pool pumps. It has a capacitor in the "head" of the motor, along with some other wiring goodies - one item looks like a thermal breaker.
Anyone have an idea of what to do with this? Any tests to perform, or should I just buy another and hope that it lasts for more than a year?
