You certainly free to do as you like and you should follow your own
decision not mine. I am only saying that to me, the more logical plan would
be to find out what the problem is before trying to solve it by throwing new
expensive openers at it when it would appear it is not an opener problem.

Even the cheap openers are not known for the kind of problem you are
having when properly installed on a properly functioning door. I really
think you are missing something and I hope to save you some money. It might
even be something with the power supply, maybe as simple as a floating
neutral.

I do wish you the best of luck and I hope that if you replace the opener
again, that it works for you.
