I recently installed the 3/4 HP Full Rate Two Speed Motor W/ Timer 115V - Round Flange - B2973T to replace a failed single speed motor. Here’s the retailer link: A.O. Smith 3/4 HP Full Rate Two Speed Motor W/ Timer 115V - Round Flange - B2973T - INYOPools.com
It works fine on low speed. On high speed, after 2 minutes of runtime, it throws a “fault 12 overload” code. After a few minutes of being shutdown with power removed, the code is cleared and the motor runs fine on low speed.
The retailer has no experience with this code. They sent a lower HP impeller, but to no avail. Fault 12, the same problem, still occurs after 2 minutes.
Does anyone have any knowledge of how to resolve this? Thanks, much appreciated!
