Hormann sectional garage door query

[gtb4]

I have a couple of questions about a wide double insulated Hormann sectional garage door which I had installed about 5 years ago. I've tried Google but it is not much help.

I've noticed that the door is not sealing properly around one of the top corners. There's maybe 1 mm on the top edge and perhaps 2mm on the side. When the door closes it seals properly everywhere but then reverses a small amount which creates this gap. Elsewhere it's fine. I'm wondering whether this reverse is on purpose for some reason (maybe to protect the seals from getting crushed)? I can't remember whether it has always done it.

The second issue is that I've also noticed a gap where the bottom seal seems to have been cut short by about an inch. Not sure how I missed this when it was installed as it's an obvious fault. Does anyone know whether the bottom seals are installed at the factory or by the fitters (who were nice guys but clearly a bit slap dash)? Would help in deciding how to deal with it.

TIA

Could some of the brackets holding the door moved of come loose meaning that gap is present? Have you tried resetting the door? mine has an issue where if it gets hot sometimes it can't close and i have to reset it and it works again.

Thanks for the thoughts. Everything is very solid fixing-wise. So not that. Do you have a Hormann door - if so does it reverse at the end of the closing process?

I can get the manual out and try resetting it but I was hoping to get an opinion of whether it should be doing what it’s doing first!

[richatnort]

Nope mine doesn't reverse it just pushes forwards for the last bit to seal itself.

[gtb4]

OK thanks. That’s helpful to know. I’ll see if I can reset it to stop the reverse from happening.

I don’t suppose you know whether the bottom seal was fitted on site do you?

Mine does not reverse and the seal was on the panel when delivered.

Every now and then I think when it is very hot when Closing it jams slightly and reopens but this is reopen in full not just a bit.

The frame on my Hormann has shifted enough that the seals don’t seal against the door. I basically had to go around undoing all the brackets on the frame and push it back into position before retightening.

[gtb4]

Thanks Jeremy. Good to know.

Crumpet - is yours a sectional or a roller? My front frame is attached to the guide rails for the door. So I would have to move the whole thing which looks like a mammoth operation. Is that what you did?

Ours doesn't reverse at all when it gets to the closed position, but it does sort of "twitch" slightly as it switches off, if that makes any sense.

FWIW ours also has a small gap where it doesn't seal properly on the top panel. I had someone out to service it a few years ago, and they didn't seem to be able to improve it. I think all the possible mechanical adjustments are already right on the limit.

[gtb4]

Thanks. I’m going to have a go at mine over the weekend to try and stop the reversing. That would make it seal properly I think.

I have a fully insulated garage and having paid extra for a super insulated door it’s frustrating that it lets loads of cold air in during winter!

I’ve had a Hormann sectional fitted recently, but with an older supramatic operator that I already had. Mine functions as you describe, it closes then backs off very slightly.

[gtb4]

That’s interesting. How old is “older”? Mine is about 5 years now.

Mine is 5 years old, self installed, on the rear brick face; not the internal access faces.
It seals properly on the garage floor, with the supplied seal which I fitted.
The upper section is on its own separate guide, and drops down after all the other sections have rotated down their guides to the final position, a small thunk is heard as it drops into place.
Mine has the optional Bluetooth module, so once installed I can verify the exact positions of it as it goes up and down..
If yours ain't sealing on the last panel in, I'd suggest the rollers on that panel need to be realigned, and the height/stroke of the motor is adjusted to let it fall properly, then let the system learn where it should go to full/nothing either way.

It’s a supramatic e3, not sure on age as it came with the house. I just ran through the reset and learning cycles and it still does the same backing off at the end of closing.

Edit to say that it has Made in 2013 on the side of it.

OK thanks. Mines an E4 made in 2020. I’m going to give Hormann a ring and see what they say.

Thanks for this. Mine works the same way with the top section being on its own guide. The door slows before that section closes. I’m pretty sure I don’t have a Bluetooth option but I’ll look out the manual.

It’s definitely the reverse which stops the door from sealing. I’ll see if I can reprogram it to improve things.

[gtb4]

I was put on to a local company by Hormann who were very helpful. It’s definitely not supposed to reverse at the end of the closing operation. They’ve suggested some ideas for me to try and see if I can get it to work properly, failing which they will come and sort it out.

Update for anyone interested.

I've found that mine does have the app / bluetooth (thanks Grey_Area). Once that's set up you can see the operator settings which includes one to adjust the reverse function. This can be adjusted in 4 stages from none to long. Mine was on medium. Short is recommended for best thermal outcome. The reverse function is to release the pressure on the gearbox. I guess you can adjust it between summer and winter if that floats your boat.

I also adjusted the frame and inserted some spacers between that and the brickwork which has helped close the gap in the top corner completely as this was still out by a couple mm or so even after adjusting the reverse to short.

The seal at the bottom is still wrong and apparently it's £40/m which is annoying (especially as the door is 5m wide) - will teach me to be more fastidious about checking work. There was a lot going on is my excuse!
