Diagnose Any Garage Door Problem Yourself
A garage door opener is a complicated creature. The thing is, your garage door opener is actually a combination of different systems connected together.
So, as you might suspect, there are a lot of things that can go wrong: A door can stop responding to your remote, make a strange noise, or just get stuck in an open or closed position. Best Garage Door Repair in Los Angeles
Many repairs can be done yourself if you have the right tools and are comfortable climbing a ladder, but there are some cases where it is much safer (and smarter) to call in a professional. Follow this step-by-step guide on how to diagnose a garage door problem so you can know for sure whether or not you need to bring some backup.
1. Check all electrical connections.
If your garage door opener is not working, first check that it is getting electricity.. Be sure to take a look at the LED lights, safety sensors, and wall panels on the motor unit to see if they are running.. If not, unplug the motor and check its circuit breaker; Flip the switch on any blown fuses and plug the motor unit back in.
2. Make sure the garage door opener is unlocked.
The lock may be on. This safety feature is easily turned on and off and, when turned on, prevents the remote control or keypad from opening or closing the garage door.
Check the green LED light on the button of the wall-mounted garage door opener. (It may be located under the plastic button, which requires you to release it with a screwdriver.) If the green button is flashing, the garage door is locked. In that case, just hold down the “lock” button for a couple of seconds until the green light stops flashing, then try the remote or keypad again.
3. Test for hypersensitive sensors.
Your garage door safety sensors are designed to prevent the garage door from closing on people, pets, cars, and any equipment that is not fully engaged. There are two: one sends a ray of light and the other receives it. Follow these tips to make sure they all work properly.
• If the LED light on either is not glowing, the sensor may think it detects something in the path of the garage door. Often times this means that the safety function has become misaligned or blocked. Make sure the two sensors are aligned correctly and remove all cobwebs, dust, or other debris from the area.
• Next, follow the wire that runs from each one to the end to make sure it hasn’t been damaged or cut along the way.
• Finally, if your garage door still won’t close and the check engine light blinks, the sensors can still “detect” something blocking the way. You can override this by pressing and holding the button on the wall-mounted garage door. If your garage door closes properly and you are sure nothing blocked the sensors before, the sensor itself may not be working properly.
4. Toy with remote control.
Most of the time, fixing your garage door’s remote operation is as simple as replacing the battery in your handheld device.
In the event that it doesn’t work, you can climb a ladder and hold down the “learn” button on the motor unit. Your garage door opener will search for a new remote signal; Press the button on your remote so the opener can pick it up, and then the opener will store the new code. Note that this will reset all the remotes that work with the garage door opener, so you will have to press the button on each one if you have two or three remotes.
Also, check for radio frequency interference. Sometimes LED lights used in garden lighting or home security lighting, even video game consoles, can create radio interference that will cause the opener to stop working. If you have any of these devices, the garage door remote control may only work when not in use. The solutions are somewhat limited: the installation of special antennas could increase the remote signal or could change the type of bulbs for others that do not cause radio frequency interference.
