Garage Door Begins To Go Down Then Back Up

Look at the top hinge on the door.

Garage door begins to go down then back up.

There may be two nuts on one track. Sometimes the sensors will be in alignment and just as the door gets close to being shut it will vibrate enough to push one sensor off. Yes it goes all the way down the track when the door is disconnected. Another common cause of garage doors acting this way is a faulty rpm sensor.

When the opener is activated the screw rotates causing the nut to move until it reaches the switch. See if you can find a manual online and go throught the setup steps again. If the door had hit a stop it would not have reversed. One for the opening limit and one for the closing limit.

Consult your owners manual or a trained garage door technician in replacing the rpm sensor. When the opener reverses the screw turns the opposite way and the nut travels back. Your garage door sensor works by having two photo sensitive devices on either side of the garage door. Then you have a binding problem in the door.

Adjust it if needed and make sure the door is positioned in the middle of the 2 tracks. A careless or rushed parking job can cause the car s bumper to block the sensor. If the door hits something hard it will reverse. In order to fix this you ll want to make small changes to the close limit setting until the door opener knows to stop once the door has reached the floor.

Here s a rundown of some of the possible reasons this can be happening. Your travel down setting needs to be adjusted. Possible reasons why your garage door hits the floor then goes back up as is the case with so many issues at the home there s no one reason why your garage door closes then opens. Parts can be purchased in online stores or directly from the manufacturer.

This is almost always the result of a dirty or obstructed safety feature. If this has been helpful please click the green accept icon.

You might consider calling a local garage door company to come and debug it for you. If the door reverses and the lights blink 10 times there s still a problem with the sensors or something tripped them on the way down. It goes partway down reverses direction and goes back up again.
