Why the Garage Door won’t work


Commercial or residential garage service professionals have much dealt with each issue you may think of at terms of the garage door repair. Still, there are issues keep surprising it, like mall insect nest that is growing right on photo eye sensor and tennis ball that has managed to knock door totally out of the track. Even though it is uncommon issue, they’re nothing door service professionals cannot handle!

Knowing what’s actually wrong with garage door might help you determine if this is the problem you can tackle or if it’s time to call someone or better still, a professional for assistance. To help you to troubleshoot the garage door issues, here’re some reasons the garage door will not work.

This may sound obvious, but your garage door transmitters can’t work without power. If the batteries used by your transmitter are dead, the transmitter would not be able to send a signal to the garage door to open.

First, check to see that the transmitter on the wall inside your garage still opens it when pressed. If it does, then you need to replace the battery for the transmitter in your car. If you have more than one car transmitter in use for your garage door, then your other transmitters would most likely need new batteries soon as well as they may have been installed around the same time.

Changing the battery on your garage door transmitter is easy. At the most, you should simply slide the door open on the back of the transmitter and remove the battery. Others might just be screwed in to keep the battery more secure as this type of transmitter requires a screwdriver to open.
After removing the old batteries, make sure the terminal sides on the batteries are in sync with the terminal signs on the inside of the transmitter. With the battery in place, test the transmitter, and check if it works, then replace the transmitter door.

You may remember a time as a kid when you and your siblings play games by closing the garage door and attempt to run underneath it as fast as you can make it out just before the door closes. Well, on garage doors installed after 1993, that risk is less, thanks to two tiny photo eyes at any side of garage entrance. The photo eyes transmit the invisible beams between one another detecting in case there is anything at garage door’s path while it closes. It is the safety measure in order to prevent the automatic doors from closing at anything as it will cause some serious injury and damage to property.

Over time, these eyes can get dirty, which can block the light from the beam. They also can eventually become misaligned and cause the eyes not to match up on both sides.

When cleaning the photo eye, you should take care not to scratch or damage the eye since it’s made of glass, like in a camera lens. The photo eye itself is quite small and just a few centimeters in diameter but can get dirty rather easily. To clean, you have to get soft & mild cloth, or streak-free cleaner. The gently wipe away dirt and residue that might have built up at eye and stay careful not oversaturate excessive wetness will cause the dirt to stick on eye very quickly.
