If your garage relies on a set of roller doors, you may be perfectly happy with the installation. After all, they work as they should on a regular basis, and you've had no cause to worry about them since they were first installed. That is, up until now. For some reason, they are not responding to your wishes, and you may find that your vehicle is stuck inside. Could this be a relatively simple problem to fix, and if so, what should you look at first?
If the door is not responding at all and there is no sign of life, the first thing that you need to do is check the power source. Is everything still connected properly, and is it possible that one of the building circuits is disabled? If everything seems to be working okay elsewhere, then have a look at the mechanics of the operation.
Dirt or Debris
Check the rails to see if there is any obstruction. Leaves, dirt or other debris can sometimes get stuck and may have been dragged further up into the structure with the passage of time. This may not be readily apparent, but look for any obstructions higher up or even above you and try to get rid of them, if you can.
Have a good look around the proximity sensors as well and see if they are clean and open. If they are obstructed in any way, then they may be sending a signal to the motor to deactivate everything for safety purposes.
If you only use a remote control to operate your roller door, then it is possible (though relatively unlikely) that a nearby device is operating on the same frequency. This may be the case if a neighbour has recently moved in and their remote control is clashing with yours.
Lastly, have a look at the structure and composition of the door to see if you can see any signs of damage that you may not have noticed before. Someone may have reversed into the door when you were not there and compromised its ability, but be careful before you try and complete any DIY repairs. After all, you don't want to make matters worse.
If you're not able to diagnose the problem in any other way, get in touch with a repair specialist. They will be able to come out and fix your door as soon as is practical so that you can get on with your day.
