You should regularly perform a garage door inspection to extend its life and reliability. The inspection checklist should include checkpoints such lubricating the door, checking the springs and inspecting the small sensors that raise the door back up if something is in its way. This is vitally important if you have children or pets in the home or that visit your property on a regular or semi-regular basis.
You want your door to close but also be ready to lift back up if it accidently does strike anything in its path. For example, let’s assume that a bicycle is left unattended and in between the door and the floor. The eye of the sensor will shoot its beam right between the spokes of the bike, and the door will still begin to lower and come down, which is what you want it to do. But if it strikes the bicycle then the door will quickly switch to its reverse mode and lift itself again. The best way to ensure that this happens in the way it was designed, just step away from it and grab it by hand. Get a feel for it and see how much pressure it’s putting on you to go into the motion of reversing it. Disconnect it and use it by hand. That way you know that the opener is following along. Determine if it’s adequately balanced out and stable. A door that is properly balanced will sit about halfway up after you’ve switched it to its manual mode. It’s always a good idea to inspect the door twice per year. If you suspect any serious issues, for example the door's balance or the spring, do not hesitate and call our representative.
