Step 1 - Check For Debris Blocking Gate's Path

First, we will check for a simple mechanical issue. You may be surprised to learn that a simple build-up of debris or a small item in your gate's path could cause your gate to stop closing! The very first step is to ensure nothing is blocking your gate's pathway. If all is clear and nothing seems out of the ordinary, move on to the next step.
