Both of my front doors only open about 2-3" before stopping, and it is a bit annoying having to wait for the motor to stop moving before continuing to push them open. If I hit the open button and then push on the door, the motor fights back to put the door to the point that it is only open 2-3". So...I have to hit the button, wait a couple of seconds for the door to open 2-3" and then stop moving, and then push it open the rest of the way. Shouldn't the door open further using the motor? And if so, how do I get that to happen?
