Automatic window opener on greenhouse

most things are sealed units these days but if you can get in to it you will probly find that the brushes have worn out ,were you would get them from I don't know,or if you can get them near the size and shape you can file them to fit,

I recon you've had your money's worth Volunteer, most things don't last 12-15 years these days.

I thought as much Heron, but it was worth asking, thanks. I'll put it on my Xmas list!

Is it worth a quick sqirt of WD40 Volunteer just incase it shifts it?

Before you remove it just check that the window has not slid sideways a touch therefore causing it to stick,it might sound daft but it happened to mine and I was able to release it, in last weeks wind it did it again and wasn`t closing properly, they are expensive so well worth checking........

Good idea drc726 my hubby said good thing to use wd 40 , it has probably ceased up .Call it old age

Know the feeling!!
