What do you do when your garage door opener doesn’t Respond?
First, unplug your garage door opener from the electrical outlet. Next, remove the garage door arm from your garage door opener. Next, lock your door closed and placed grips or clamps on the track above the middle roller. This will ensure the door does not open while you’re working. First, position the ladder in a manner that will allow you to keep your face away from the winding cone and winding bars.
As you unwind the spring. Insert one winding bar into the winding cone. while firmly holding onto the winding bar. Loosen the set screws and the winding cone. Ensure that the set screws are not in contact with the door shaft. Insert the second winding bar fully into the winding cone. Lift up on the second winding bar and remove the first bar. Then insert the winding bar into the next hole on the cone and repeat this process until all tension is removed from the spring.
You will want to count the total amount of quarter-turn you remove from the spring as you are unwinding it. This is the same amount of tension that you will be reapplying later. Take your time and concentrate on what you are doing. Eliminate all distractions from your work area before unwinding or winding torsion Springs.
If your garage door has two torsion Springs, repeat this process on the other spring. All tension must be removed from the garage door before you can proceed.
Loosen the Limit Screws.
First, loosen the set screws on the cable drum. Then slide the cable drum away from the end bearing plate. Now remove the cable from the cable drum. You may let the cable drop to the floor first. Remove the lag bolt holding the bottom track bracket to the wall. Next, remove the fasteners that hold the bottom bracket in place. Slide the track to the side and remove the bottom bracket from the door. Remove the cable from the bottom bracket and then completely remove the cable from the door. Then prepare the new cable by cutting any pieces of tape that are wrapped around it. Always be careful using a sharp knife. Now attach the cable to the bottom bracket.
Replacing the Rollers.
Install the roller into the bottom bracket and thread the cables behind the rollers on the door with the cable behind the roller on the bottom bracket. Install the bottom bracket onto the garage door. Align the bracket with the holes. It was removed from, and reinstall the fasteners, making sure to tighten them before proceeding.
Now re-install and tighten the lag bolt into the track bracket.
Take care to reposition the track bracket in the same location it was originally first. Ensure the cable is clear of any obstructions and is running directly from the bottom bracket to the cable drum. Insert the cable into the slot in the cable drum. Make sure the cable is properly seated into the cable drum as noted by the correct graphic on the screen. Then make sure the cable is properly tracking in the grooves in the cable drum. Slide the drum firmly against the end bearing plate and tighten the set screws on the cable drum. Do not overtighten the set screws holding the drum in a manner that will keep the cable tight on the cable drum. Placed locking pliers on the shaft, letting them rest against the wall. This will hold the cable tight on the cable drum.
Resetting the Up and Close-Limit Screws
Insert the winding bar into the winding cone, making sure the winding bar is inserted all the way into the cone. Lift the first winding bar and insert the second winding bar into the next hole and the winding cone. This is a one-quarter turn. Continue to wind the spring until the proper amount of turns have been applied. Once the number of turns has been reached, let the bottom winding bar rest against the door.
Tighten the set screws against the shaft. Insert the second winding bar into the winding cone and lift slightly removing the bottom lining bar and testing the strength of the set screws.
