Next jump the belt at the sprocket pulley at the opener 2 notches on the belt.
Loose belt garage door.
However you may have to adjust the travel slightly.
The manual does not indicate how to solve this problem.
I recently replaced our chain driven garage door opener which functioned fine for 9 years with a chamberlain myq opener which runs off of a belt instead.
The average life of a belt drive garage door ranges from 7 to 10 years with some which will need belt changing after only a few years while others might not for nearly two decades it depends on the quality of the product.
When opening the door the belt on the non pulling side is very loose.
A constant grinding noise could be a sign that your garage door opener s chain or belt is either too loose or too tight either way it needs adjusting.
The belt should still have a little slack when the door is closed.
It was nearly a direct swap and all works as desired except.
This would reduce the slack and less tension on the belt.
I am sorry no more videos in 4k takes too long to edit.
A belt drive garage door opener uses a rubber belt instead of chain links to open the garage door this makes it relatively soundless compared to its chain counterpart.
