COULD BE A BAD REMOTE, I WOULD TRY ANOTHER ONE FIRST.
COULD BE A FREEZER ETC. PUTTING OUT INTERFERENCE.
Anytime a door opens and/or closes randomly or doesn't work consistently I look for a smashed wire between the motor unit and the wall button.
If the wire is smashed the insulation becomes so thin that power will leak thru the insulation and activate the door or interfere with the remote signal.
Loosen the staples with a small screwdriver and slide the wire about ½ inch to move any areas of thin insulation away from the staples.
The second thing would be a bad wall button or a remote with a sticking button.
Or a remote in someone
