Sometimes, your garage door is not functioning the way it should. For simple problems, you could almost certainly do some of the fixing yourself. Here are some common garage door problems you can repair yourself:
Your garage door goes up and down by itself. No, it's not the bogeyman. The explanation is actually simple - there must be someone in your neighborhood that uses a security or access code similar to the one you are using. This can cause interference with your radio receiver. Radios in police cars and airplanes also have the same effect. How do you make sure this does not happen again? Simply change your code.
The process for changing a security or access code differs from one garage door opener to another. As a general rule, you just need to hold the transmitter close to the opener's box and push a certain transmitter button for thirty seconds (consult your manufacturer's manual to find out what button to hold down). Most openers that are new models are equipped with a rolling code that changes automatically once the transmitter is used.
Your garage door goes halfway down and back up when you try to close it. In this case, you might y be using a garage door that has a safety sensor system that detects if there is any obstruction to the door coming down and tells the machine to pull the door back up. Your door automatically opens up again when it senses any obstruction - a bucket or broom, maybe. Just remove the obstruction and your door should again work perfectly.
This problem may also happen if your sensor's lenses are dirty, dusty or has a condensation built up (sometimes spider's web). The system will think that something is in the way, causing the door not to close. Keep the lenses clean.
Nothing happens when you press the transmitter. If you suspect that your transmitter is not working, you may want to change the battery or look for the power source to see if it is working. If this does not fix it, your transmitter might be damaged and needs to be replaced. Call the service company.
