No matter how often the remote control system for a garage door is checked, there is really no way to fully prepare for the door suddenly not working. The best-case scenario is it stops functioning when leaving the house allowing for the opportunity to make a mental note to research the problem.

But then again, the remote might quit working when driving up to the garage in the middle of a torrential rain or full-blown snowstorm. Neither of these situations is very appealing.

Logically the first thing to check would be the battery in the remote control. To avoid one of the previously mentioned unpleasant situations, performing regular battery checks is a wise idea.

If the remote works after installing a new battery, problem solved. If a new battery does not work, then test the wall switch. Again, easy enough to leave the house through the garage using the wall switch, but not so convenient when returning home. If the wall switch operates the garage door, then the problem is with the remote control system, and it will need to be repaired or replaced.

Most homeowner’s know-how ends at the remote control battery or the wall switch. If neither of these opens the garage door then the problem is within the garage door unit itself.

The problem could be as simple as lubricating the rails, or as intricate as something broken in the trolley carriage. Trying to fix problems in a garage door system without knowledge of how the system works, can often lead to more problems.

For example, incorrectly adjusting the chain tension could throw the whole garage door off track and damage the rails, the rollers, or bend the door itself. These types of mishaps can become extremely expensive to fix but can be easily avoided by calling a garage door specialist first.

Clearly, if the choices are to be stuck outside in inclement weather without remote control power to your garage door, or getting in and out of the car to use the wall switch every time, then it is time to have the garage door repaired correctly. Anything much beyond changing out the battery in the remote control, or checking the fuse panel for the wall switch, should be left to the expertise of a trained garage door expert.
