Title: Up and over garage door tensioning
Post by andyl3004 on Sep 19^th, 2018, 9:57pm

Hi

I have an up and over Novoferm garage door - the basic one sold at Selco.

I mounted it. It has never had any tension. It does not raise itself. I can open it but have to lift it dead weight and when lowering it the brakes stop in every hole in the way down and the when lifting it the steel cables are slack. I have tensioned it at least 20 revolutions. I know it is supposed to be 26 revolutions judging by the standard of other up and overs.

But not sure if I'm doing the wrong thing because the opppsite end of the spring there is a pin in the end of the spring. It's not crook pin shaped - it doesn't have a curved section it's just a straight pin. But like Henderson or other up and overs I thought maybe I should have removed it. But the installation instructions said nothing about this pin.

So not sure shall I just keep tensioning or remove the pin? I haven't taken a picture but it feels like the tensioning I have done has caused the spring to stretch and to begin to coil over the tensioning nut.

There are a few videos on YouTube which look like they show you how to fit and tension Novoferm doors. It may be worth Googling your door and add YouTube to see if they cover your exact door.

Thanks. Already did that. Most show a pin being inserted to tension spring but this door already had a pin inserted so trying to see if anyone else mounted one of these. Bought from Selco.

It may be worth getting a specialist garage door repairer round. I imagine, unless there is something else wrong, he can sort this in a few minutes in which case it shouldn't cost too much. I called one out at my last house, the door had never worked properly and he knew exactly how to set it up and I never had a problem with it again.
