There are a few things that could cause this. Misaligned safety sensors will prevent your opener from closing the door. Even if the sensors are correctly aligned but something is blocking them or their lenses become dirty, they could still prevent the opener from closing the door, or force it to reverse each time you try to use your remote or your keypad to do it. Obstructions in the tracks can also prevent the door from closing, and problems with the motor or the drive system are also likely to result in a similar problem. If you can close the door manually, then the problem is most likely something to do with the opener. If your door won’t even close manually, then there could be something wrong with the cables, the tracks, or other hardware parts. In any case, you should let a professional take a look - and that is exactly where our team at Garage Door Repair Yonkers come in. Your opener and remote will be troubleshooted, and the rest of the system will be thoroughly checked professionally, quickly, and affordably!
