Liftmaster Garage Door Closes Then Opens Again

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.

Liftmaster garage door closes then opens again.

Your garage door s logic board is the brain of your garage door opener. These steps should fix most doors. This will cause the trolley to move into position and reconnect to the garage door. The symptom of this is a garage door that is in constant motion opening fully then immediately descending only to start the same cycle again.

Hopefully after you read this you won t have the same problem in the future. Get logic board replacement. If the garage door does not close completely or begins to close and then opens back up again the down limit switch needs. 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.

Now press the remote control. If your garage door opens ok but won t close then it s possible the safety reversing sensors are not correctly aligned. There may also be loose wire connections inside the button housing itself. Don t just assume that if the path is clear that the sensors are ok.

To reconnect the garage door to your liftmaster garage door opener manually close the garage door pull the emergency release handle down. When the logic board wears out it can cause your garage door to close then open and vice versa without explanation. This problem bugged me for several months. Close the garage door with the opener and watch it closely as it closes.
