Fan/Light help please

goldenboy1818
Hi I fitted a new envirovent extractor in a bathroom, they had a 12volt one before but the zone position was ok for mains. Obviously removed the transformer.


However after leaving at night the customer has rang to say the light that operates when switched on with the fan, has a constant dim light. Bulb is a small 3watt led. It must be getting some slight back feed, only when the fan iso is on. Has anyone experienced this before, greatful for any input. Thanks

    As a quick check, see if the light goes out with a small load in parallel with the lamp (anything that consumes a few tens of watts should do)

    If that works, invest in a small capacitor and put it in shunt with the lamp in the back of the holder or in a small box.

    (you can buy one at exorbitant price with a label on it) or without once you know the value needed for far less..
