Garage automatic doors problems.
Generally for automatic garage doors cables balance out the lifting of the door s massive material so that it would just swiftly go up and down when the sensor is activated.
These are heavy duty springs that do all of the hard work when opening your door.
The garage door cable enables you to pass through a heavy door safe and sound.
The metal rollers and hinges on a garage door can become stuck making it hard for the garage door to open and close.
Automatic doors have sensors located along the track usually somewhere around knee height.
This is a problem that will require you or a service person to replace it.
A partially working garage door is easy to ignore but also very easy to fix.
If your garage door is closing fully and then reversing to open again then it may be due to a problem with the close limit switch.
Finally it s possible the garage door opener s motor has burned out and isn t operating at all.
