Garage Door Opener Rail Bows Down

I believe there will always be a slight bowing as the pushing and pulling of the door exerts pressure on the rail.

Garage door opener rail bows down.

Firstly check that you re using it within the range required for your opener. Thus the problem with the opener moving and the door not. You may also need to reprogram your keypad or replace the batteries in it. My only suggestion is the ensure that the door operates properly and easily without the gdo and then re connect the door.

Second the opener should be lower. Every opener i ve ever seen or installed has a slight slope from the end of the rail back to the motor. It s illustrated in the chamberlain manual under installation. Also verify the antenna on the motor unit is in the proper placement.

Go to your local home improvement store and buy some angle iron and lower the power head. Normally it s only about an inch or so. My gdo rail bows slightly when opening and closing as well. If it is too high then the draw bar arm that pushes the door is at too much of a down angle and instead of pushing forward it pushes more down.

See the section in your manual titled position the opener when the door is fully opened the opener rail should be max 2 above the edge of the top section.

If you re too far away this can cause a problem with opening or closing the door. Disconnect the door from the opener trolley and open and close it manually.

Also check the rollers. The tracks might be bent or loose causing the rollers to bind.
