Roller Shutter Doors - Again

[puffernutter]

More woes I'm afraid.

This is an "in tube"? (tubular motor?) roller shutter door.

I noticed a few weeks ago when stopping the upward motion, the door would drop back a couple of inches. That seemed to go away.

Now it is worse and dropping back 4-5 inches when stopped going up. However if you then go up again it will only drop back a short distance.

When my van is under the car port, it doesn't fit in all the way and I'm concerned the door will drop on the roof.

So, I am not familiar with the braking mechanism on these door. Is it adjustable, or is my motor drive just worn out and I need to work out how the dickens I'm going to replace it - it was a real pain getting it up there in the first place and I really don't fancy getting it down if I have to repair it.....

Cheers

I havnt taken one apart but I've always assumed it's just a simple gear or latch into a gear to hold them onto place...

Chances are it's just a bit sticky.... put it up and down 6 inches a load of times and see if it free's it off? (Maybe not too fast in case the motor gets hot)

It's generally on the opposite end to the motor, a flat block which on mine is adjustable, it's basically an inertia cam, not sure it stops the roll from moving, more stops it in event of a failure. The motor stops it from creeping, so maybe look there. The guys who install them will come and service them, or at least the guy who did mine does.

I bought this from a supplier in Preston and fitted it myself. So I have very little information regarding what is inside and how it works!

As for servicing, again I have no idea what is serviceable or how to service it! It was a major PITA getting the roller and door up there without any mechanised help and I really do not fancy getting it down to service it and I cannot see how (or what!) to service it up there!

Cheers
