I have the DG240 it has been working fine since Aug 2007, a couple of days ago I found that it would not move west, it would move east OK. At the motor the lights are flashing correctly, I did a reset at the motor, nothing. By hitting the west button several times I got it move west. Then I could move it east with no problem with the east button.
It would not move west unless I pushed the west button several times and it would move west. So the only way I could move west is to hit the west button several times and then it would move.
I got out my hi-tech instrument ( hammer) and tapped it (motor) with the handle several times and it seems to be working ok, I hope.
Any thoughts would be appreciated.
