Hi
My toilet extractor fan has stopped working - it is a Wickes one with timer and was fitted when we had the bathroom done 18 months ago - I am OK with straight replacement electrics but not the problem tracing bit ! So I want to figure out whether the unit has gone or whether there is a problem in the switch or circuit.
I have taken the cover off the unit to test the circuit. There are 3 contacts on the terminal block feeding the extractor - a red one a blue one and a brown one. If I switch the light on (also normally controls the fan) there is power on the red and blue cicuit but not the red and brown circuit.
There are 2 power cable supplies coming into the unit - from them there is one red supply to the red terminal, one black one to the blue terminal, and one red and one black supplying the brown terminal.
So is the lack of power between the red and brown terminals normal ? Do these symptoms indicate that the unit is faulty and needs replacing - which I can do. Or would you think there may be a problem at the light switch (wire popped out perhaps) ?
I havent looked in the switch because one of the screws seems to be cross threaded and I can't get it out easily - i'm sure if I force it i'll snap the back box connector and need to replace that - so would rather not do that unless I know I have to.
Thanks for any tips.
