If you're wondering why your garage door is opening by itself, some of the most common reasons include: A short in the circuit board. The garage door circuit board, or logic board, helps operate the entire garage door. Circuits in the board can get damaged over time, causing the door to open and close on its own.

Why does my garage door start to close then open?
Your Logic Board Needs Replaced. Your garage door’s logic board is the brain of your garage door opener. This brain can wear out in time, so you could need a replacement. When the logic board wears out, it can cause your garage door to close, then open (and vice versa) without explanation. Get Logic Board Replacement.

Jammed Control Buttons
Malfunctioning Remote Circuit Board
- Sometimes the problem is not just a button on the remote that won’t work; it might be the device’s circuit board. The circuit board is like the brain of the remote control, and a defect can cause it to send wrong signals to the unit. If the remote behaves erratically as to open the garage door on its own, its circuit board might be faulty. Such fau...
Faulty Logic Board
- Just like personal computers and other computing devices have motherboards, garage door openers have logic boards serving as their brains. The logic board—the equivalent of a motherboard in a garage door opener unit—can wear out over time. When that happens, it may become unable to perform its function correctly. It can also malfunction due to a manufacturing …
Overlapping Signals
- Suppose you have a garage door opener made before 1993, and you recently reprogrammed it; overlapping signals might be a cause. In that case, one of your neighbors or somebody nearby was likely using their garage door remote control at the same time it programmed to your garage door opener. Now when the person uses their remote to open their garage door, it also operates …
Blocked Safety Sensors
- Modern garage door openers are equipped with sensors as a safety precaution. A sensor is mounted on the tracks on each side of the garage door and has a beam pointing directly at one another. If an object or person is at the doorway, it will break the beam, alerting the system of its presence. With that, the sensors will prevent the door from closing. While the sensors are an exc…
Misaligned Safety Sensors
- If you have a residential garage door opener manufactured after 1993, the chances are that it has a pair of safety sensors on the garage door flanks. These sensors have beams that must point in the same direction for them to work. As it is, the repeated opening and closing of the garage door often creates vibrations that can loosen one or both of the sensors over time. A loosened senso…
Incorrect Limit Settings
- Garage door openers have a component that limits or controls the extent to which the door can travel during opening or closing. This component is called a limit switch. The component must be set correctly to stop the door once it reaches its fully open or closed position. If the limits are set incorrectly, it may cause problems. Some of the common problems associated with incorrect li…
Damaged Control Wiring Or Electrical Circuits
- The garage door opener is a sophisticated system that uses various components to perform its functions. These components are connected through a system of cables that transmit signals. Some wires run between the motor unitand the safety sensors, while others run between the motor unit and the door. All of these small gauge wires carry electrical signals, making them sus…
