Garage door repair ranks among the most critical home maintenance tasks homeowners face today. This comprehensive guide covers everything from basic troubleshooting to complex repair solutions.
Understanding Garage Door Mechanisms
Modern garage doors incorporate several mechanical and electronic components working in harmony. The system includes springs, cables, rollers, tracks, and an opener mechanism. Understanding these components helps identify potential issues before they become serious problems.
Torsion springs store and release energy to lift and lower the door smoothly. Extension springs, found on either side, help balance the door’s weight. The opener motor provides the power, while safety sensors prevent accidents.
