There are several reasons why your roller garage door might stop working. 

First, if you’ve just had your roller garage door installed and you’ve been showing it off it may stop working because the thermal override has overheated. This happens because of excessive use and it usually just takes 20 minutes for it to cool down and start working again. 

However, if you’ve let half an hour pass and the door still won’t respond to your requests for it to open or close, you can troubleshoot by looking at the following settings. 

Check the Power

It seems like an obvious question, but you’d be surprised how many people think their door is broken only to realise someone has accidentally disconnected the power supply. Before you call anyone, double check your roller garage door is still connected to the mains power and that the socket is switched on. 

Sometimes when we’re moving things around in our garage, we’ll take out the plug absentmindedly and forget to put it back on. It’s an easy fix!

Check the Remote Control

Sometimes roller garage doors stop working simply because the remote control has run out of batteries. If you’re finding the door won’t respond to your remote control, it might not be an issue with the actual door, it could just be the remote control. Replace the batteries and double check. 

Try the wall switch if you have one installed and see if that makes the door respond. If it does, then you know the issue is with the remote control. If it’s not working, then it’s an issue with the door itself. 

Make Sure There Are No Obstructions

If your roller garage door is open and refusing to close, look at the sensors and make sure there’s nothing blocking the way. The sensors on an electric garage door are very sensitive, and there to stop the garage door from closing on even the smallest of obstructions. It’s protecting children and pets from having the door close on them. 

Small obstructions include things like leaves, sticks, or stones that might get in the way when you’re moving things around, or blow in on a windy day. Double check and make sure there’s nothing blocking the way and then try again. 

Look for Physical Damage

Roller garage doors have a lot of equipment to function properly, and if something is broken, then the entire garage will stop working. Have a look at the cables, springs, control box, anything for any sort of physical damage. If a spring has broken, you’ll usually know by the noise, they sound like a firecracker or gunshot when they snap. A spring is only going to last so long and will need to be replaced eventually, so if you’ve got a snapped one you’ll need to get an expert out to replace it. 

The same applies to cables. They can snap, break, or even just move out of place and require adjusting. If you’ve got a damaged cable, you should always call a professional for help. 

Reset Sensitivity Settings

Your garage door sensitivity settings can sometimes be too low or too high, which means the door won’t open or close. You can reset them by reading the manual and making the adjustments. Luckily, this fix doesn’t need professional help and you should be able to manage it on your own. 

Adjust Limit Settings

Limit settings tell your garage how long it needs to lower or raise in order to open or close fully. If these are off, then when your garage hits the ground it will think there’s an obstruction and hasn’t closed properly. The slats usually bounce back open and won’t shut. 

You can check the manual, or look at the motor and adjust the limit settings to see if this works. It may take some time to get it exactly right, so be prepared for some trial and error. If the door isn’t closing, you want to lower the setting, and if it won’t open, try increasing it. 

Contact Your Garage Door Provider

If none of the above has worked and you are still having problems with your garage door, the best option is to contact the people who installed it for you. You should have been directed to a team who can support you with any ongoing issues, and if it’s still in warranty, you could even have it replaced. 

They’ll be able to send out an expert who can troubleshoot for you and make any necessary adjustments or repairs.
