Garage Door Bounces Back Open

This is almost always the result of a dirty or obstructed safety feature.

Garage door bounces back open.

A careless or rushed parking job can cause the car s bumper to block the sensor. Your garage door sensor works by having two photo sensitive devices on either side of the garage door. 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. This brain can wear out in time so you could need a replacement.

Maybe you have to hold the garage door button down for the door to close. You push the button to close the garage door. If your garage door is closing fully and then reversing to open again then it may be due to a problem with the close limit switch. This video will show you a few quick.

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. The measurement is used to reset the up limit switch on your garage door opener. Open the garage door and watch it closely as it opens. The garage door will automatically go in reverse.

If you garage door is lowering then reversing back to the open position there could be something obstructing the sensors. It goes partway down reverses direction and goes back up again. Measure the height where the door stops while it is being opened. If these can t see each other when the door is almost shut it will send a signal to the garage door motor to open back up.

The two dials may have a picture of a house with a garage door next to them. Turn the down limit switch screw clockwise one turn with a flat blade screwdriver if the garage door closes and then begins to open back up. Your garage door s logic board is the brain of your garage door opener. When the logic board wears out it can cause your garage door to close then open and vice versa without explanation.

You want the one on the left. Try the door and if it still re opens turn the same dial another complete revolution. Check to be sure these two sensors on either side of your garage door. When the garage door opens about halfway or 5 feet from the ground and stops the up limit switch needs to be adjusted.
