Having installed (and re-installed warranty replacements) many of these motor, I have found that there is really no way to repair them. the factory warranty people generally just offer a replacement. Had them come out once and re-program the drive, actually hooked a laptop to the electronic control and "flashed" the software to the latest revision. Didn't help. Had one that kept dying and being replaced. Turned out there was a voltage problem coming from the auto controller that the customer wouldn't fix. Fried the electronics and I finally gave up on him after 4 replacements.

If yours was a replacement motor that was installed, it has a two-year from date of manufacture warranty. If it came on a pump, probably only 1 year.
