They generally have a spring-supported mechanism which is operated typically by a switch on the wall or a remote-controlled device. There are many moving parts, so it stands to reason that from time to time some of those parts will stop working.
When beginning your check of the doors, make sure that all the correct warning labels are there and clearly visible. Can you clearly recognize the manual release handle and would anyone else be able to identify it?
As well as the door itself, take a good look at the framework. What kind of condition is it in? Is it showing any signs of wear and tear? Any problems you see, contact a professional to do the work.

Its also important to instill in them the dangers of playing with strings and pulleys attached to the doors mechanism.
So, as you can see, there are simple things to check to ensure your garage door is working efficiently. Remember though, that if you do encounter a problem, its best to check with an expert on what to do.
