[Solved] Adjusting DROMA THP-40 Sectional Garage Door: Solutions for Jumping Segments (Video Included)

Savek 4287 10
Best answers

How can I fix a sectional garage door that jumps on one side while opening?

The door was ultimately fixed by adjusting the springs, which had shifted in their mounts over several years of operation [#20188765] Before that, the suggested checks were to inspect and lubricate the roller shafts and hinges, tighten all guide screws, verify the roller axle clamps and hinge pins, and check the horizontal/vertical guide bend connections [#16606004] [#16606038] [#16614015] The owner also confirmed that lubricating and rechecking those parts did not change the behavior, and the jump happened only on one side while manually pushing the middle of the second panel eliminated it [#16613096] [#16618732] In the end, a professional spring adjustment solved the problem and it stayed fixed for years [#20188765]

    Hello,

    Can anyone help me with the adjustment of the DROMA THP-40 4 sectional garage door?

    For some time, she started to jump when opening (the second segment - from the top). I showed it in the attached video.

    From what I can see, something is blocking the treadmill, but lower or on the other side.

    Nothing's blocking it. I have a video of closing and opening (I cut this fragment out of it). It looks like the entire segment is skipping, but only on the side I was filming. The other side moves without jumping.

    Brush the roller shafts.

    Check, buddy, all the screws that are in the guide, lubricate the axles of the rollers in the hinges, besides, check if any clamps of the roller axles have not loosened, additionally check the connections on the bend of the guide, vertical / horizontal. Check that all hinges are tightened or that the connecting pin has not jumped out of them.

    I checked everything and lubricated it. It looks ok.
    I have the middle hinges as shown in the pictures. In some, the lower screws twist a little (they go into the foam), but there are two more under the hinge that they hold.

    I noticed that when manually lifting the gate and pressing in the middle of the second panel from the top (from the outside), there is no such jump.

    All in all, it is possible that the panel jumps over the panel as the gate folds on a bend, so try to feel if the gate folds, sometimes it does not blur the panel or the side flashing of the panel

    Basically nothing more than so far. Ie. the "gills" in the panels are slightly scratched, but that was the case right at the beginning.

    So it remains to check the diagonals on the horizontal guides, and take the rollers out of the sleeves and check if there are any burrs on them and, if necessary, lubricate them.

    I checked and relubricated. All right.
    Anyone have an idea how to deal with this?
    Is it possible to somehow adjust this gate?

    I will write how the topic ended (better late than never).
    A professional came and adjusted the springs.
    For several years of operation, they have shifted in mounting.
    He adjusted and as you can see until today (five years pass) everything is OK.
