Question

I own a bailey senator California caravan purchased new in 2009, intermittently the omnivent extractor fan will not allow us to extract from the van, the intake starts up first and works after a fashion. When trying to select the extract the lights iliminate but they will not stay on to extract. Occasioanlly we have been lucky in getting it to extract but rarely

Answer

It sounds like it is a fault with the electronics or the switches, this part is available as a complete spare part but there are a few different types, hopefully you will be able to identify the correct one from the drawing on the Omnivent spare parts page.
