ok so I have tried what you listed, then i tried removing the fuses 59, 14, and 17 for 20 seconds and replacing them, I also tried removing the battery for 20 seconds and then reconnecting.
the gate is doing the same thing, but I did find that if I tell the gate to open and then easily assist the gate opening or closing with my hand it works as it should. but under its own strength it will open or close about 6 inches then revert and chime 3 times.
im wondering if the gate Pistons or Hinges whatever you want to call them are applying to much resistance and the motor thinks something is in the way? any advice from here would be appreciated. can I detach the gate motor and just use it manually for a while?
