Loose Belt Garage Door

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.

Loose belt garage door.

The manual does not indicate how to solve this problem. This would reduce the slack and less tension on the belt. 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. If you hear a squeaky noise when the door is opening and closing this is most likely a sign that the pvc part of the exterior frame weather stripping and the weather stripping between garage door sections have probably dried out and are.

Tim the belt needs to be loosened at the trolley with the door closed. However you may have to adjust the travel slightly. The belt should still have a little slack when the door is closed. When opening the door the belt on the non pulling side is very loose.

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. 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. Next jump the belt at the sprocket pulley at the opener 2 notches on the belt. Brand new chamberlain garage door opener with excessive slack in belt drive.
