When you have Velux blinds, it's important that they work properly to allow you to control the light and heat in your home. However, sometimes it happens that the blind does not go all the way down, which can be frustrating and inconvenient. In this article, we are going to see the possible causes of this problem and give you some solutions to solve this problem so that you can take full advantage of your Velux blind.
Why does the Velux blind not go all the way down?
There are several possible causes that could explain why your Velux blind does not go all the way down :
- Incorrectly programmed limit switch : It happens that the limit switch of the Velux electric or solar blind is deprogrammed or incorrectly adjusted. In this case the awning no longer recognizes the lower limit switch and can no longer close all the way down.
- Tension problem in the cords : If the lifting cords that connect the blind to the control rod in the trunk are too tight, this may prevent the blind from lowering all the way down.
- Lack of lower attachments : The lower clips holding the cords may be clogged or damaged.
- Rolling mechanism problem : It is possible that the bearings which ensure the rotation of the cords are no longer functional, blocked and/or that the fabric does not unwind badly.
- Manufacturing or installation fault : It is possible that there is a manufacturing defect in the blind itself or an installation defect, which may prevent it from closing completely. If the problem appears soon after installation, you should us Velux assistance for replacement under warranty.
Note that this list is not exhaustive. There may be other possible causes why your Velux blind does not come down all the way. It's better to check each of the causes above and consult a professional if necessary to identify the exact cause of the problem.
How to repair a Velux blind that no longer closes completely?
For repair a Velux blind that does not go all the way down, manipulations are relatively technical. Generally, from a financial point of view, it is better to completely replace the blind than to change part of the mechanism.
Reprogram the limit switch of the Velux electric blind
When your store electric Velux no longer closes completely, the majority of the time, the problem comes from a limit switch incorrectly adjusted at the time of installation or which has become unprogrammed. In this case, you will need the recalibrate. To do this :
- Press the up or down button on the electric blind remote control
- While the blind is moving, turn off the power supply to the window via the circuit breaker or transformer
- wait a minute
- Turn on the power supply
- Select the blind on the remote control
- Push the button stop then immediately on the button fermer
- Let the blind move until it stops by itself
If the procedure worked, your Velux blind should go all the way down again.
Check the lower awning attachments
The manual Velux blind may no longer close all the way down because its lower attachments are clogged, damaged or broken. If the lower attachments are dirty, clean them. If they appear damaged, replace them with new ones. You can find this spare part easily on online merchant sites.
Check and replace lift cords
Check the tension of the lift cords (also called cords). They can be too tense and, in this case, prevent the Velux blind from completely descending to the bottom. If so, you will need to adjust the tension of the cords at the lower ties and/or the upper ties. They may also be faulty and need to be replaced.
These manipulations require you to open the winder box. They therefore require to be particularly handyman. If you still want to try to do it yourself, you can consult video tutorials on the net. For example, Takfonster's video " How to change the cord of the DKL Velux Slim awning?«
Disassemble and reassemble the Velux blind
It may also be that the Velux blind does not go all the way down because it was mounted incorrectly. If the problem occurs very soon after installation, we advise you to uninstall then reinstall the store. To do this, refer to the assembly instructions for your awning model or to a video tutorial like the Velux one :
To find the installation instructions of all Velux awning models, go to their website > customer service > installation service.
Check and replace winding mechanism
It's possible that bearings which ensure the rotation of the cords are no longer functional, blocked and/or the fabric rolls up and unrolls badly around the axis. It may also be that tension spring be too tight. In this case, the spring must be reengaged and relaxed by making fewer turns.
In this case, you will either have to dismantle the box to check the condition of the mechanism and carry out the manipulations, or replace the entire box and therefore buy a Velux blind.
