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.

Now press the remote control. Your garage door s logic board is the brain of your garage door opener. As these wires short against the housing the electrical impulse causes the door opener to activate. Close the garage door with the opener and watch it closely as it closes.

This will cause the trolley to move into position and reconnect to the garage door. Try opening the garage door with the remote and see what happens. 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. When the logic board wears out it can cause your garage door to close then open and vice versa without explanation.

This brain can wear out in time so you could need a replacement. To reconnect the garage door to your liftmaster garage door opener manually close the garage door pull the emergency release handle down. There may also be loose wire connections inside the button housing itself. This problem bugged me for several months.

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. 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. Don t just assume that if the path is clear that the sensors are ok. If the garage door does not close completely or begins to close and then opens back up again the down limit switch needs.
