Many people have been in this position before, where all of a sudden and for no apparent reason their garage door won’t open or close. If this sounds like something you are experiencing then there are a couple of things that could be causing the problem, and the main component is the overactive sensor.
Usually the problem can be remedied without the need for calling out an expert, and you can have your garage door opener working like normal within a few minutes. Below we have outlined some tips if your garage door isn’t functioning correctly.
The first thing you will need to locate is where the sensor is on your garage door opener, and luckily most installations will have the sensor in the same place. Look for a little eye that is by the garage door, it should look something like the image that we have used above.
This is the sensor, and the job that the sensor does is to scan the area where the garage door opens and shuts to make sure that there are no obstacles in the way when the door is activated to either close or open.
Most door sensors are sensitive and this can lead to some simple issues in why your door has stopped operating problem which we are going to look at now.
Firstly you will need to look for anything that the sensor is picking up in the area where the garage door shuts and opens. Now, remember that the sensor is very sensitive so even things like cobwebs can cause the sensor to think that there is something in the way, causing it to stop working.
As your garage is a haven for spiders and cobwebs this could be the main problem you are facing, so start by removing any cobwebs that could be causing the obstruction to see if this remedies the problem.
If it’s not cobwebs then just look for anything other obvious things that could have made the sensor stop working.
Another major problem with garages is that they collect dust over the course of time, and this dust can settle on the sensor, and obstruct the sensors eye from seeing clearly. Sometimes the problem of a non-operational garage door can be solved by simply wiping the sensors eye clean so it doesn’t think that there is something in the way.
Once you have cleaned the sensor give your door another try to see if it closes and opens again.
If none of the above has solved the problem then the issue could be deeper and you will need to do some trial and error to what is causing the problem. Firstly, make sure you check that power is going to the battery and the LED light is showing green. If the garage door is not responding then it could be down to an issue with no power going to it, or a dead battery that isn’t being recharged.
The next thing to look for is if the remote has broken or the batteries need replacing. If you have a keypad entry system then try typing your code into this to see if the garage door opens and closes, if it does then your problem is going to be down to the remote control. If you don’t have a keypad then you will need to try and replace the batteries in your remote to see if that solves the problem of the faulty garage door.
Sometimes it is as simple as popping in a couple of new batteries into the remote to regain control of the door.
If you are connecting the door to a Wi-Fi system then you will also want to double check that everything is working as normal here. The things you want to check for is the connection from the router to the door to make sure that the network hasn’t been erased by accident. If it has then you will need to set up the network again and you should find that this solves the problem for you.
If the battery appears to be ok, the remote isn’t the problem and you have tested the Wi-Fi connections, then the sensors eye may have failed and you will need to get a new one fitted in order to restore full functionality back to your garage door. If this is the case then call an electrician to your house who can advise you of the next steps you will need to take in order to replace the sensor.
Usually a sensor for a garage door opener comes as a replaceable part so you don’t have to worry about getting a whole new garage door/opener unit.
