The extractor on our Starspirit has a problem. It’s an Omnistor Omni-vent.
When I twist the operating knob to open the roof vent sometimes it works but often it just won’t turn no matter how hard you try. Have you had this problem and resolved it? If you have, can you give me some guidance please?
I used to have an Autocruise Stargazer with the same problem. I tried taking it apart and cleaning the mechanism but still the problem persisted. I found the only way was to exert clockwise pressure on the operating knob, as if trying to open the vent, and then leaving it alone still with the pressure on and after about 40 seconds the vent would pop up.

Thanks for your response Keith. That is exactly the problem.
The attached pic shows the mechanism. I think that wear and tear means that the flap is going a bit low and the lifting mechanism can't cope with the initial start up.
Having spent some time thinking about it the only solution I can think of is to put some sort of stop between the flap and the motorhome roof to stop the flap dropping right down. Would need to be careful about leaking though.
Next time I feel brave I will get on the roof and have a shuftie.
Is It possible its the sealing rubber sticking, try some talc on the seal or perhaps some olive oil, but not any wd as this does have a detrimental effect on certain rubber /plastics and does make them expand so they tend to be hard to work
Is it possible to remove the rod and put a light kink in it, so it just takes out the locking action of the arm when it go's down, it sounds as if the arm is going past its resting point, and locking up
The idea of a kink to stop it locking hadn't crossed my mind. The whole problem seems to be that the sliding part goes too far (possibly because of wear and tear) hence your solution.
Thinking on this perhaps a less drastic solution could be to put a short piece of plastic pipe or similar over the rod to stop the slider going quite so far. see pic.
We have the same problem and have cleaned the mechanism and used different recommended lubricants......all to no avail. Sometimes it works easily and other times, nothing at all. Quite random and very frustrating! Very effective when it does work though.
Reckon it's a basic design fault as the angle is too acute to start the lifting process from the closed position.
