You have to wade thru the linked thread from my previous post but member Ponz sent me his broken units. I opened it up and I drew the diagram (schematic) for the circuit board and attendant wiring.

Right. Photo shows cracked plastic gear on the units Ponz sent me to study. So the motor spins freely slipping on the gear. As mentioned in other thread, you can replace this with a metal gear. While Scottv may also have this problem, since he doesn't even hear the motor whirring sound, there's something else going on.
