What is the common problem of a garage door?

The most common problems of a garage door include noisy operation, door not opening or closing, broken springs, misaligned sensors, and worn rollers, especially in Canadian cold climate. Common garage door problems include broken torsion springs, which are most common failure, springs last 10,000 to 20,000 cycles, about 7 to 12 years, and when broken, door will not open or is very heavy. Second, misaligned or dirty safety sensors at bottom of door prevent door from closing, causing light blinking. Third, worn rollers and hinges causing grinding noise and jerky movement. Fourth, garage door opener issues like stripped gear, dead battery in remote, or motor failure. Fifth, door off track due to impact or worn cables. Sixth, weatherstripping and bottom seal failure causing drafts and water leaks, common in Canada with snow and ice. Seventh, remote control not working due to battery or programming. Eighth, door imbalance due to spring tension loss. Ninth, frozen door in winter when ice forms at bottom seal. Tenth, noisy door due to lack of lubrication. Preventive maintenance includes lubricating rollers, hinges, and springs annually, checking balance, cleaning sensors, and replacing weatherstripping. Most common problem overall is broken springs and sensor misalignment, which account for majority of service calls, costing 200 to 400 dollars to fix springs and 100 to 200 dollars for sensor alignment.
