I was very optimistic when I found these detailed instructions to repair the activators. Very clear and easy to follow, but alas… See the three plastic nubs that the activator attaches to with the two screws? They seem to be very weak spots. One of mine snapped off, and once that happens, I’m not sure there is any solution. Any ideas? A potential waste of a good motor. I wonder if this is a “designed to fail” kind of thing.
