Unraveling the Mystery: Why Does It Happen?

One of the most common reasons for a garage door to behave erratically is sensor misalignment. Garage doors are equipped with safety sensors that detect obstructions in the door’s path. If these sensors are misaligned, they may erroneously signal the door to reverse.

2. Limit Switch Issues

The limit switch determines how far your garage door travels during its opening and closing cycles. If the limit switch is improperly set, it can cause the door to close only to reopen immediately. Adjusting the limit switch to the correct settings is crucial for resolving this issue.
