Garage Door Opener Troubleshooting: Beginners' Tips
If you are having trouble with your garage door, then you should consider performing a few simple garage door opener troubleshooting techniques. In order to correct any problem that might have happened to your garage door opener, you will have to be aware of all the things that can go wrong. There are a few simple tricks which can help you avoid having to call in a professional.
Replace the Battery
Even if the battery you have put into the garage door opener is not yet dead, you should always replace the battery first. Some batteries just don't seem to work with some devices, so add a new battery, and try the garage door opener again.
Clean the Sensor and Opener
There might also be a problem with the garage door sensor and the connection between it and the opener. Dirt is a common cause of problems for the opener, so consider wiping both it and the sensor down before trying anything else.
Adjust the Sensor
The problem could be with the sensor, rather than the garage door opener. A common problem is that its position has been altered (perhaps by birds knocking into it), which can cause a big problem. Check that the sensor lines up with your garage door opener.
