Pump not starting

[gilkman]

I have a century SP3220Z1M pump motor (2.5hp) that will not start. I have tested the breaker, the relay in the Omnilogic panel, and the power at the connectors on the motor itself and I am getting a full 240v at the motor. I have also replaced the capacitor (tested the new one to make sure it was good) and the shaft on the motor spins freely.
any other suggestions, or am I looking at a new motor at this point?

Thanks!

If you need to go with a new motor I would suggest a variable speed like the Nidec Neptune 2.7THP as it will save you a lot of money over it's lifetime. If you have spare relays in your OmniLogic panel you can also control speeds using digital inputs as shown in the Installation and Operation Manual.

G-Man,

Are you sure you have 240 Volts AC??

I ask because to test 240 VAC, you need to test between the L1 input and the L2 input to get a valid reading. If you tested L1 to ground and L2 to ground, you can often get a false reading.

Thanks,
