BFT Sliding Gate randomly opening and closing

[Adamit]

Hello All,

I have a BFT Deimos sliding gate that when fully closed, will randomly start opening and then stop half way, start closing again, stop before closing, and start opening again.
The gate has worked perfectly fine for a decade, and suddenly started playing up.

I have replaced the photocells, both entry and exit pin pads, gate motor and board. I have also tried using the autoset function so the gate can relearn itself, however the problem still happens right away afterwards. 

Open to all suggestions, I'm at a loss as to why this would suddenly start happening, Please help!

Did u ever fix this issue ?
