Last year, I replaced our up-and-over garage door with a roller-shutter version. It wasn’t new; our neighbour converted her garage so I bought her nearly-new door but that means I didn’t have a professional installer to fall back on when it stopped working recently.
The garage door control system is a Somfy Rollixo RTS and last week, we found that the door would come part way down and then stop, as though there was an obstruction. After winding it down manually one morning, Mrs W was not happy and I promised to take a look when I got home. I couldn’t find the problem – what’s more I couldn’t troubleshoot it using the manual either. What I did notice though was that, rather than the two red lights I’d expect to see for a safety-edge transmitter low battery indication, I had one red light on the control box, and one orange light on the safety-edge transmitter (which is fitted to the door curtain).
I found I could over-ride the cut-out by pressing and holding the remote control button, and set off to the Internet to find a replacement 3.6V Lithium AA battery. First mistake was not reading the Google results carefully enough and ordering a 2/3 AA battery from Farnell/Element 14. Now I can’t return it as I can’t find a courier who works with consumers and will carry Lithium batteries! In the meantime, I’ve bought the correct (AA) battery and, this morning, I swapped it over, after which I found the door operated as it should. That was a relief, as I feared that swapping over the battery would wipe some settings and require me to re-programme the door.
So, why blog about something as trivial as changing some batteries? Well, because the instruction manual is wrong and my experience might help someone else!
