A garage door is not going to be nearly as useful as it is meant to be if the light bulb happens to go out. This can cause immense amounts of problems, and it is in your best interest to get it fixed as soon as possible. The light bulb can be replaced just like a regular light bulb can.
The first thing that you will need to do is turn off the light switch and remove the old light bulb. In most cases, the lighting fixture is rather high so be certain to use a sturdy ladder to reach the bulb casing. Once you have gotten to the opener, you will likely need to drop the hinge cover down to access the bulb. Once the hinge is activated, remove the bulb by turning into counterclockwise.
The next step is to check the wattage of the bulb. You need to make certain that you put a new bulb in that has the correct wattage. If you put in a bulb that has a higher wattage, you may be asking for trouble. It is also suggested to avoid using the new energy efficient light bulbs because they do not typically light up as much as traditional bulbs. This is important if you rely on that light to help you get into your home.
As soon as you have the bulb, climb back up the ladder and install the new bulb by turning it clockwise. Once the bulb is in, turn the switch on before closing up the cover. If the light is working properly, simply go back up the ladder and close the light casing.
If the light is not working, unscrew the bulb. Shake it and make sure that you cannot hear it rattling. If it rattles, the bulb is likely blown. Try a different bulb. If there is no rattle, reinstall the bulb. Make sure that you are screwing the bulb straight into the light bulb holder. Then try turning on the bulb again.
Your bulb should be on and working properly. If you have tried multiple bulbs and you still cannot get the light to turn on, you may have a slight problem. Refer to the instruction manual for assistance, or you can even contact your local electrician to help.
It is not too difficult to change a light bulb in your garage door opener. It may take a little patience, but you can definitely do the job.
