Extractor fan in bathroom - jumper 1 has been removed

Brevitt · 7 May 2024

Hi,
We have a Manrose Mons 100 extractor fan installed in en-suite. It turns on when we shower but isn’t turning off. I have left it for over 30 minutes with no luck.
The very sparse instructions say that removing jumper 1 removes the timer which should give 15mins over run. I am thinking that the jumper 1 must have been removed.

Can this be replaced? Looking at the diagram in the ‘instructions’ is not helpful. It shows the position of the jumpers but not how to reinstate the timer function.

Grateful for any help offered! Thanks

I cannot make it out in your photo, but possibly the jumpers are of a type commonly used on computer pcb's, disk drives and the like. Have you anything like that, fro which you could 'borrow' such a jumper?

Is it perhaps just the humidity keeping the fan running?

Thanks, They look like 2 small pins sticking up out of a small rectangular base.
I don’t think I have anything like that hanging around, but I can always ferret around and see.

Definitely not the humidity! The room was absolutely clear well before I gave up waiting!! But thanks for the thought,

Yep, they sound the same!
Any computer repairer would have boxes of them, if you are stuck..

I found a friendly chap in a computer repair shop, showed him a close up photo of where I needed to replace the jumper, and he found one for me. It is now fitted. Perfect, thank you for your help.
