Liftmaster Garage Door Closes Then Opens Again

Hopefully after you read this you won t have the same problem in the future.

Liftmaster garage door closes then opens again. If the garage door does not close completely or begins to close and then opens back up again the down limit switch needs. As these wires short against the housing the electrical impulse causes the door opener to activate. This brain can wear out in time so you could need a replacement. If your garage door opens ok but won t close then it s possible the safety reversing sensors are not correctly aligned.

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. Try opening the garage door with the remote and see what happens. There may also be loose wire connections inside the button housing itself. These steps should fix most doors.

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. This problem bugged me for several months. Don t just assume that if the path is clear that the sensors are ok. Now press the remote control.

Close the garage door with the opener and watch it closely as it closes. 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. 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.
