Troubleshooting Garage Door Opener Liftmaster - Garage doors come in several shapes and sizes. Their functions vary from basic security of an area to concealment that is decorative. Most doors could be broken down into groups or several basic styles. Typical modern garage doors for residential applications are usually predominantly of the overhead sectional variety.

Before, with operating an overhead garage door the greatest concern was the possible hazards associated with the springs used for balancing the door weight. Pre mid-1960's garage door installations normally relied upon a pair of stretched (tensioned) springs to assist the operation of the garage door pivoting hinges. These springs became loaded (tensioned) as the door was transferred to the closed position.
Some of the most dangerous aspects of those spring systems was that after an amount of time, frequently with no care or inspection, the points of attachment of those springs would rust or become feeble. This weakening of the springs or points of attachment would frequently result in an inadvertent explosive failure fling the broken spring parts around the garage, embed the spring or steel parts to the garage walls, other items in the path of travel or automobiles.
