I have a US Motors 1081 Pool Motor with the specs below. The pump started to hum without turning over. Did some research and changed out the capacitor a No Name 189-227 MFD Round with a Dayton 189-227 MFD Round 110-125VAC. Pump started up without incident. A few weeks later, pump started to hum again and would not turn over. Thought the new capacitor went bad so changed it out with a new same spec Dayton from Grainger. No luck. Have had to "jump start" the pool pump with my drill which starts the pump just fine and it keeps running for the entire timer cycle. However, it will not start by itself. I can turn the shaft by hand as well as the impeller. It just seems that the capacitor does not have enough juice to kick the motor over. Can I increase the voltage of the capacitor to the 220VAC version or will this not work? Is there another troubleshooting item I should try before taking the motor into the shop? I have read about rapping the motor with a hammer, but have not deployed this technique yet. I am trying to work from simple solution to more complex, with the most complex and expensive being to replace the pump motor. The pump is approximately 2 years old at this point. Any help or other troubleshooting tips would be most appreciated. Should additional information be need, kindly contact me. Thank you.
