I am getting pissed at this gate. I had to habe a new motor put in after the old one died and parts were no longer available. This fucking thing was supposed to be the best there is, bit now it has failed for a second time.
That blue plastic disc turns with the arm, and you can see the maroon plastic pieces attached to it that hit the switches that stop the motor in the open or closed positions. In the bottom photo, the switches are the back parts mounted on the red platforn. When the disc misaligns, the gate doesn’t know when to stop. Tonight, it opened too much and hit the base, triggering the godawful loud impact alarm.
This thing cost too much to be this unreliable.
