Change the timer on extractor fans?

Question

Hi, I have a 4inch Steeple extractor fan in my bathroom but i still have a mould problem. I need to extend the length the timer on the extractor goes on for. How would I do this... Please help - I am so fed up of cleaning mould off my ceiling...!

Answer 1

Remove the cover,There is a s***w underneath that you turn to adjust the timer.Replace cover.

Answer 2

If your bathroom is below the loft,are you sure your loft insulation is up to scratch?

Answer 3

Increase timer over run as in answer No1,but I'm not sure that will fix your problem. You not only have to extract water vapour you also have to make sure that you have sufficient intake of air i.e. Leave the window slightly open,leave the door slightly open or fit an air brick
