Garage door cables enable the winding and unwinding of the springs as the door closes and opens. Common issues with cables are simple wear and fraying. They wrap around a drum fixed to the torsion tube and sometimes fall off that drum. The real problem may not always be with the cables themselves. Issues with garage door tracks and rollers can cause problems for the cables. Sometimes when a spring breaks the cable will tangle on the torsion tube. In this case the garage door can become "locked."
GARAGE DOOR LOCK
You should avoid the garage door if it becomes locked. The amount of tension that is stored in these mechanisms can be lethal when released. Call a professional repair service (preferably us) to get the problem fixed.
The obstruction sensors at the foot of a garage door are a safety measure in case a person or object is under the garage door as it is closing. Most are an infrared LED emitter/receiver pair, like what is found in a TV remote/receiver. These sensors can become misaligned, their wiring can become loose or damaged, or their internal electronics may fail. Sunlight is also known to cause sensor problems, likely because the sun emits a broad range of optical frequencies including infrared, which can affect both the emitting and receiving LEDs. In some cases what may appear to be a sensor issue may actually be an issue with the opener's limit or force settings, which may in turn be a result of problems with the track or rail.
REMOTES AND KEYPADS
In many cases, simply replacing the battery on a garage door remote will fix it. Remotes usually use coin cell or A23 batteries, both of which can be found in most stores. Sometimes the issue may actually be with the obstruction sensors, as they may be preventing the door from moving even when the remote's signal has been successfully received by the opener. Other issues can be in the programming. Remotes can forget their code. Some problems with remotes will require replacing them. With time, electrical contacts for the buttons can wear out and the electronic components responsible for tuning to a frequency can diverge, causing the circuitry to drift too far from its intended frequency. Keypads are wireless and have many of the same problems that remotes do.
Garage doors can have a few different problems. The hinges connecting panels can wear or break, the bottom weather seal can wear out, the struts on the door can be damaged. Some issues with garage doors can be subtle. For example, wood doors absorb moisture and as a result become heavier and larger. After it rains, the added weight on a door may not play nicely with the garage opener's settings, which were set for a door with less weight. The increased size of the door, though small, may be enough for it to get stuck at certain positions. We both repair and install garage doors.
