What does it mean when your garage door opener starts blinking?
There are a few different things that could be going on when your garage door opener starts blinking. It could be something as simple as a loose wire or something more serious like a malfunctioning sensor. Here are some of the most common reasons why your garage door opener might start blinking:
1. Unplugged door opener
This is one of the most common and lame reasons so always make sure that your garage door opener is plugged into a working outlet.
2. Not receiving power: If your garage door opener is plugged in but still not receiving power, you may have a tripped circuit breaker. Check your home’s main electrical panel to see if the breaker for your garage door opener has been tripped.
3. The opener is not properly grounded
If your garage door opener is not properly grounded, it may start blinking. To fix this, simply ensure that the garage door opener is properly grounded.
4. Sensors are dirty or misaligned
Garage door opener sensors can become dirty or misaligned over time. This can cause the opener to start blinking. To fix this, simply clean or realign the sensors.
5. Faulty remote
If your garage door opener remote is not working, it may be because the batteries are dead or the remote is not properly paired with the opener. Try replacing the batteries in the remote or reprogramming the remote.
If your garage door opener is overheating, it may be because it is working too hard. This can happen if the door is heavy or if there are objects blocking the door from closing. To fix this, simply remove any obstructions and make sure that the door is properly balanced.
How can you troubleshoot and fix the problem yourself?
Here, we will discuss how you can troubleshoot and fix your garage door opener when it starts blinking.
1. Sensors repositioning
The first thing you will want to do is check your garage door opener sensors. If they are misaligned, simply reposition them. Follow the steps given below:
The sending sensor and the receiving sensor are the two sensors you’ll need to find. These sensors are located near the garage door track.
Equip yourself with a measuring tape or a ruler once you’ve discovered these sensors. Your sensors should be 6 inches off the ground in the garage.
Check the distance between the sensors and the floor to see if they’re correctly aligned. If they aren’t, you’ll need to reposition them.
To reset your safety reversing sensors, unscrew the wing nut using a wrench. Adjust the sensors up or down until the LED light stops flickering and produces a constant glow after loosening the wing nut.
Tighten the wing nuts until they’re snug after you’ve adjusted each sensor to its proper place. Make sure you’re not overtightening.
2. Check the door
Next, you will want to check the door itself. Make sure that there are no objects blocking the door from closing. Also, make sure that the door is properly balanced. You can do this by checking to see if the door is level with the ground. If it is not, you will need to adjust the door.
How can you prevent this from happening in the future?
There are a few things you can do to prevent your garage door opener from starting to blink.
1. First, make sure that you are regularly cleaning and inspecting your opener. This will help to ensure that it is in good working condition.
2. Regularly check the door and the sensors to make sure that they are clean and in good working condition.
3. Finally, do not overload the door with too much weight. This can cause the opener to work too hard and eventually start to blink.
If your garage door opener is blinking, it may be because the batteries are dead or the remote is not properly paired with the opener.
To fix this, simply replace the batteries in the remote or reprogram the remote. If the opener is still not working, try repositioning the sensors.
We have mentioned the step-by-step process above. If you have checked all of these things and the opener is still not working, it may be time to call a professional.
We hope that this article was helpful and that you were able to fix the problem yourself.
How do I know if my garage door opener is properly grounded?
There are a few ways to check if your garage door opener is properly grounded. The first is to check the manufacturer’s instructions. Most openers will have a specific section on grounding.
Another way to check is to use a multimeter. Set the multimeter to the “ohms” setting and touch one lead to the ground terminal on the opener. Touch the other lead to a known ground, such as a water pipe. If the multimeter reads “0 ohms,” then the opener is properly grounded.
How often should I lubricate my garage door opener?
It is generally a good idea to lubricate your opener at least once a month. This will help to keep it in good working condition and prevent it from starting to blink.
