There are several simple things you can do yourself to help keep your garage door running properly. First, make sure your emergency release cord is pulled and all spring tensioners are completely relaxed before attempting any repairs or adjustments. Then, lubricate the track rails and down-track with a silicone spray to prevent friction. Also, make sure all of your hardware is securely tightened (but not too tight to strip) and that the carriage bolts are flush with surface of the roller hanger. Finally, check the alignment of your garage door by following the steps.
