Frequency Drive Motors

Carrier Variable Speed Motor was not working at all. We replaced the motor module and now it just "bumps" back and forth. When we spin the shaft by hand, we can feel the resistance of the magnets, but the motor still wont come on. We checked the harness for continuity. Any suggestions?

    They make a good ecm motor/control test meter for these

    Call your supply house. They might even have one you can try.
