Garage Door Cable Repair Phoenix, AZ

Your garage door system relies on two cables that work in tandem with the springs. When the door closes, the cables wind around drums mounted at the top of the door opening. When the door opens, the cables unwind and the springs provide the counterbalance that makes the heavy door feel light. If one cable breaks or slips off its drum, the door becomes unbalanced. One side drops lower than the other, and the door may jam in the tracks. This puts stress on every other component in the system, from the rollers to the opener. There are two common cable setups: – Torsion cables work with torsion springs and wrap around cable drums at the top of the door. – Extension cables (also called safety cables) run through the center of extension springs to prevent the spring from becoming a projectile if it breaks. Both types are critical for safe operation. Cables do not always snap without warning. Here are signs that your cables may be failing: – Visible fraying or rust. Take a look at the cables next time you are in the garage. If you see strands separating or rust forming on the surface, replacement is overdue. – The door hangs crooked. If one side of the door is lower than the other, a cable has likely come loose or broken on one side. – The door drops too fast when closing. Healthy cables control the descent. A fast drop means the cables are not doing their job. – You hear grinding or scraping. A cable that has slipped off its drum can rub against the door or tracks. Phoenix’s intense summer heat accelerates cable wear. Metal fatigue happens faster when temperatures consistently exceed 100 degrees, and most Phoenix garages are not climate controlled. That means your cables are baking in the heat every day from May through September.
