Garage Door Opener Rail Bows Down

My only suggestion is the ensure that the door operates properly and easily without the gdo and then re connect the door.

Garage door opener rail bows down.

Normally it s only about an inch or so. 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. Also check the rollers. It s illustrated in the chamberlain manual under installation.

I believe there will always be a slight bowing as the pushing and pulling of the door exerts pressure on the rail. Second the opener should be lower. 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. Also verify the antenna on the motor unit is in the proper placement.

If you re too far away this can cause a problem with opening or closing the door. 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. Go to your local home improvement store and buy some angle iron and lower the power head.

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. You may also need to reprogram your keypad or replace the batteries in it. Every opener i ve ever seen or installed has a slight slope from the end of the rail back to the motor. 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.

Thus the problem with the opener moving and the door not. Scroll for more items post 848621 10 30 2015 at 13 15 1 780 days old by mb1280 checkrate likes i ve been trying to alleviate some loudness in a garage door and this seems to be an answer but i don t know exactly why.
