    Bathroom fan power

    Electricians

    I have power (using a mains tester screwdriver ) going to the fan switch in air cupboard. Power showing going to the new fan.
    It has a humidifier sensor. I ran the shower but nothing? And ideas.
    It’s a new fan as the other one never worked when I moved in.

    "Hi Tim,

    If the fan has a humidifier sensor then it will have a separate switch live wire. You should have a 3 core and earth cable running from the isolator in your airing cupboard. Lots of fans are different but terminal inside the fan are usually identified by L - Permanent Live N - Permanent Neutral L1 - Switch Live.

    "Using one of these screw drivers is no use for this job you will have to make sure you have a neutral connection and watch what you are doing as if there is a connection for a timer there will be a permanent LIVE cable at the fan connection you will also have to go and check the connection at the light switch for the fan or the triple pole switch for the fan if there is one.

    Really if you are not sure what you are doing contact a recognised electrician not a handyman and they will carry out the repair to current standards.
    Hope this helps."

    "Hi Tim, you'll need a approved voltage tester to test between live and neutral for 230v. You'll probably need a qualified electrician to check everything over for you."

    "It sounds like you do not have the correct wires you will need a 3 core and cpc cable to make this work"
