A garage door is among the biggest moving parts of your home, and many families use it several times a day. Given how often it runs, problems are bound to happen.
Thankfully that the majority of problems come from a handful of parts. Knowing what to look for will save you time, money, and stress.

Broken and Worn Springs
The torsion springs handle nearly all the weight whenever you use the door. Springs are wound under enormous tension, which is why they eventually wear out.
When a spring breaks, the signs are clear: you may hear a loud bang from the garage. Never try to replace a spring yourself — a single mistake can be extremely dangerous. Always call a trained technician, and do both springs together so the second one doesn't fail soon after.
Opener and Motor Failures
The opener unit stop responding for all sorts of reasons, and only some mean a big repair. Check the easy stuff first: a fresh set of batteries often solves the problem.
If one control works and another doesn't, the issue is likely the remote or keypad. However, a motor that runs but doesn't lift, the cause might be a stripped gear that calls for a repair.
Track and Roller Issues
A door that looks crooked could have slipped out of alignment. It often occurs after an impact. In any case, never keep operating it — continuing to use it can cause more damage.
When Cables Fail
The cables and drums support the springs to lift and lower the door evenly. Once a cable fails, the door may hang crooked or get stuck. As with springs, they carry a heavy load and are not a DIY fix.

Fixing Automatic Gates
Automatic gates add security and curb appeal, but they bring their own set of issues. Gate motors may stop working during an outage, and the beams may need realignment.
A gate that stops halfway can indicate a motor issue. Since gates combine mechanical and electrical systems, a trained pro should handle the work.
Preventing Problems Before They Start
The best way to avoid costly breakdowns is a yearly tune-up. Keeping the tracks clean once or twice a year goes a long way to the life of your system.
When something does break, calling a licensed local professional is always the safest route. A trained expert can diagnose the problem quickly and save you from bigger repairs down the road.
