You didn't say how big the motor is or what the make is. I have a
Hayward filter, pump and motor. I had similar problems with mine and
the starting capacitor fixed it. But, more and more stuff happened, and
I think an additional cause of my issues was wearing bearings. I
replaced the motor (can't remember the price but way less than $600) and
I found the newer technology resulted in a much quieter motor and pump
assembly which appears to be much more efficient as well. This is a 3/4
HP motor on a 220v line.
