While an automatic garage door may work for years without a problem, chances are it will malfunction at one point or another. In some cases, parts may have worn out and need repair or replacement. Check out a company like National Garage Remotes & Openers if you're looking to replace your garage door opener as you might be surprised at the number of options available.
But in other cases, it may be something that is very simple to address. One of those things may be the remote opener that you use for your garage door.
Before you assume that you're going to need an entirely new garage door opener or will face expensive repairs, note a few simple things to check first. These may easily get your door working again.
1. The code
If you notice that your garage door doesn't open and close as it should after it's been repaired, the code for the opener may have been inadvertently changed. The remote opener works by sending a code to your garage door, which in turn tells it to open. This code keeps your opener from opening and closing all the garage doors on your street, and if it gets changed in the unit that controls the door but not in the remote, the two pieces cannot communicate with one another. You should have an owner's manual that tells you how to change the code for both the remote and the unit inside your garage, so try reprogramming the code first and note if that fixes the problem.
2. Excessive heat and cold
It might also be that the parts inside the remote have been worn out; if you leave it clipped to your car's visor in the bright sunlight every day, this could cause damage to internal parts. Excessive cold can also damage its parts.
Note if your car is parked in hot sunlight all day or if you leave your remote opener in the car while it's parked in the garage during the dead of winter. In those cases, it may be best to simply replace the opener altogether and note if it now works, and take it inside with you rather than leaving it in the car.
When you hit the button to your garage door opener, it needs to send a signal to the sensors of the unit that opens and closes the garage. Note if the unit is blocked in any way so that it cannot receive that signal. Do you store sporting goods and other items on overhead shelves in the garage? If so, are they blocking the housing? Clear a path for the signal and this may very well fix the problem with your garage door.
