Garage Door Opener Rail Bows Down

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.

Garage door opener rail bows down.

You may also need to reprogram your keypad or replace the batteries in it. If they look to be in good shape and you are still not sure what is causing the problem i recommend you have a qualified door technician come take a look at this. 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.

The tracks might be bent or loose causing the rollers to bind. The front of the opener should only bearly clear the door when it is at its peak going around the curved part of the track.

Second the opener should be lower.

Firstly check that you re using it within the range required for your opener. Every opener i ve ever seen or installed has a slight slope from the end of the rail back to the motor. My gdo rail bows slightly when opening and closing as well. I believe there will always be a slight bowing as the pushing and pulling of the door exerts pressure on the rail.

Disconnect the door from the opener trolley and open and close it manually. Also check the rollers. Thus the problem with the opener moving and the door not. My only suggestion is the ensure that the door operates properly and easily without the gdo and then re connect the door.

Open the door by hand and when it is at its peak measure it and make sure the bottom of the rail clears by 1. It s illustrated in the chamberlain manual under installation.
