I hope someone can help me. I have a bedroom with a en-suite bathroom. The bathroom light turns on the fan and when the bathroom light goes off, it remains on for 15 mins. I recently replaced the bedroom light next door from a halogen unit, to a 4 way LED spot. Now, if the fan is running in the bathroom and I turn on the bedroom light, it shuts down! This is random it does not always do this. Is it possible my new LED lights are interfering with it in some way? Any help appreciated.
