admin You maybe need to re-tension the spring unit, depending on the make of your door.If the spring requires tensioning or slackening – fit the crook pin on the right hand side by locating through the hole in the spring shaft and locating around the canopy arm in the head bracket. Hold the spring plug tight with a toggle bar in one of the four holes to maintain the tension.
Loosen the two Allen screws in the spring plug.
Using a second toggle bar, turn the spring plug one or two turns up to tension or down to slacken the spring.
Tighten the two Allen screws and carefully allow the spring to take up the tension before removing the original toggle bar. Ensure that the cables run down behind the cones and are in the outer grooves as shown.
Remove the crook pin.
Operate the door to make sure it is correctly balanced.
You will probably need help to do this, or call in the professionals.

Garage Door Opener Repair? I have a Crawford 1/3 HP garage door opener. Recently, it will only partially open. Sometimes it opens as far as 3 feet off the ground; other times it will open less than a foot off the ground. The chain DOES move, it just stops moving when the door reaches 1-3 feet off the ground. I have to open and close the door manually now. How can I fix this?

admin The garage door opener does not actually lift the door, it assists the springs in lifting the door. If you have a large spring on the wall above the door, the brackets on either end of the bar that attach to the track sometimes wear out and the bearing binds on the bar causing the motor to stop. You can try the adjustment screws on the opener, but I don’t know why it would all of the sudden get out of adjustment that much. That spring is under high tension and can be dangerous.
