On either side of the garage door, if your door opens but does not shut. It could be your remote control sensors, if you have them, that transmit an invisible beam between themselves, are dirty or out of alignment.
These sensors get dirty over time, blocking or even misaligning the light beam, resulting in the eyes not matching on either side of the garage door. To gently remove any dirt, use a smooth, clean cloth and a streak-free cleaner. Check the alignment.
For it to shift, the metal track on which your garage door runs must be positioned correctly. If bends in the rails or gaps between the rail and rollers can be found, you have a problem. The heavy door compounds these problems of alignment and can make the door potentially hazardous.
Ensure that there is no build-up of debris covering the tracks or in the way of the photo eye sensors on the garage floor. To stop them being clogged up, check all the tracks for grit or mud and wipe them down periodically.
