Taking Care of a Reversing Door05/30/2016 Back To Blog
Bent Track Repair
You press the button of the opener remote like you do every day, the motor starts working smoothly, yet you suddenly notice it lowers the door just to one point and then brings it up. Why is this happening? Most often, the track is bent. The rollers which have to guide the door down to the floor get stuck and cannot move further down. The solution involves straightening the track. When the bending is too severe, the component should be replaced with another one for the door system to function normally again. To reduce the risk of track bending, you should watch out for obstructions in the form of pebbles and remove them timely. If necessary, the tracks should be cleaned with solvent or brake cleaner on a regular basis. The will prevent the building up of sticky dirty which can obstruct the path of the rollers.
Troubleshooting Safety Sensors
The job of the sensors is to signal the opener when an object passes underneath the door. The opener stops the door from going down and reverses its movement. However, when the sensors don’t work, the door will keep reversing even if there is nothing underneath it. This actually helps to maintain the required level of safety until the problem is solved. The first thing to do is to wipe the sensors clean and to align them to aim at each other. Check to see if they get any power as well. If these devices are clean, properly aligned and receive power yet still don’t work, then they must have failed and should be replaced.
