Not sure about other peoples, but in my case it was lack of maintence
and cleaning, they were automatic so I just forgot them, next time I
will look after them better.

Possibly leakage of fluid from the operating capsule.

That has always been the reason for failure of mine. Seals go, oil leaks
out, broken.

The seals tend to go. I suspect hard winter frosts cause them some grief
too. Mine lasted longer when the greenhouse was heated.

If the vent window jams, the auto mechanism will destroy itself (the
immovable object meeting the irresistible force! But the latter will
prove to be resistible, I'm afraid). In the end either the seals will
go, or something will distort.

I've only had one auto vent opener fail in over 30 years, and that was
through a jammed window.

By the way, be /very/ careful if you do find the window has jammed. If
the auto opener is still working, and the window suddenly comes loose,
it will be flung open with extreme force. If the opener fixing comes
off the window, the window is likely to pivot all the way back onto the
roof glass, or come loose completely if you are very unlucky.

I take the cylinder in for the winter (not going to need venting, and on a
rare bright day, we open the door from "office" to the greenhouse and get
some free heat), and tie the vent shut so winds won't flap it about. We'll
see how much this helps their longevity.

Thanks for replies. No sign of leakage, so cleaned and greased. Tried
under hot/cold taps....no movement.
