Hello Experts.
My background: I am not electric/electronic qualified.
My garage door closes and opens on press of a button. There is a black box (connected by a chain) - I believe this is the central controlling unit. I have attached pictures of this.
Recently, it opens back on itself after reaching the floor! It doesn't open back fully, just about 30cm from the floor.
What could be the issue?
Thanks in advance.
