All electric garage door owners know well that openers can create several problems. From sensors misalignment to the need to reset the travel limit of the door, opener parts might keep the door from closing or opening. So, how can we find out what the real problem is? Whether the problem is simple and can be fixed on the spot or you need to call Garage Door Repair Highland Park to help you out, there is need to discover what's wrong with it first. The best way to do this is to troubleshoot it. You just have to follow some steps, which will give you an idea of the problem. Just follow common sense. What do openers need in order to work properly? For example, they certainly need power unless you have a backup battery installed. So, start from there and carry on checking other garage door opener parts until you find the reason why the door plays games with you.
Discover common opener problems
Even if you are certain that there is power in the house, make sure all lights are turned on. There are lights at the sensors and the wall button panel and they should be green. Also check that the opener unit is plugged in and there is no problem either with the socket or the wires. Next thing you can do is to check whether the lock button at the main panel is pressed. In this case, the garage door clicker won't work at all. In this case, you should open the little cover on the panel. If the green light is constantly on, this is not your problem but if it blinks, you should hold the lock button pressed for a few seconds to unlock the door.
Most problems though begin when the sensors are hit by bikes or cars and they lose alignment. Make sure both lights are turned on. If not, move them a little bit till they are facing each other and their beams meet. Then, both lights will turn on. They must also be clean so wipe the lenses and lastly check their wires following their route all the way from the safety eyes to the wall and the main opener unit. If they are damaged, they must be replaced. The battery of the remote must be replaced too if it's dead. Sometimes, the problem begins when the wrong battery is inserted in the remote controls. Some are thinner than others. In this case and until you get the right battery for your clicker, remove it and elevate a bit the tiny steel round plate underneath. This should fix the problem.
If you open the cover of the opener unit, you will discover that many parts can cause problems to the way the electric operators work. The main circuit board could be fried in a bad storm or blackout, the antenna might get broken, the ridges of the gears might get damaged over the years and the capacitor might be leaking. The funny and frustrating thing is that led bulbs often interfere with each other. If you have led bulbs in the garden, you might notice that when they are turned on, the opener doesn't work. All you have to do in this case is to replace the garden bulbs.
For the chain drive openers, make sure the chain does not sag but it's not too tightened either. It must move inside the rail but if it's too tight, it will soon break the gear. If the overhead door gets stuck, it might be something wrong with the installation of the opener. The rods passing through the rail must be connected with tiny clips. If they are missing, the door might vibrate intensely and the opener might get stuck.
