    Hello guys,

    Avid reader of DIYnot but only just signed up, and i have my very own question that if i may i will put forward to any experts who can help me here.

    Right so my extractor hood is 13 months old (just out of warranty). The fan motor stopped working. So i want to try to wire the fan motor up to the light switch to rule out the fan switch being faulty. Or alternatively which wires do i use to test the fan motor by bypassing the switch?

    Can someone help me out here? i have drawn up a diagram of how its all wired up (please do not laugh hehe).

    Looking at the diagram i am tempted to remove the black cable from the choc block and place it with the brown (live). What do you think?

    Appreciate your help.

    my DIY wiring diagram....

    Thats not the logical way to go about testing/diagnosing the problem. Plus, if you can't figure out how to do what your attempting, with live mains, leave well alone.

    Letme add the other method i have tried with the multimeter

    The light switch terminals BROWN + WHITE (grey) get 240v on the light switch terminal

    WHITE (Grey) doesnt touch the fan switch terminals. Only BLACK, RED, BLUE, BROWN does. SO if i try BROWN + red or brown + other colours it dont get any Voltage.

    If i try BROWN from fan switch to WHITE (grey) on the light switch it gets 240V if i try red, blue or black from fan switch to white(grey) it gets 240v.

    So with this method am i safe to say the motor is dead?

    I want to physically verify this, am i safe to say BLACK, RED AND BLUE are fan speed cabling? and that i could remove any one of them from the choc block and place onto the BROWN and that should bypass the switch and therefore soon as i plug the mains in it should turn the fan on instantly? i just want to test it for a split second......
