My bathroom extractor fan is switching on when lights for other rooms are switched on. The extractor is on a switched live setting with an isolator switch.
It happened after a couple of light fittings and a light switch were changed, so could someone advise if it's something as simple as the live and neutral in the light or the L1/COM in the switch being connected the wrong way round?
Note, when the isolator switch is OFF, the connected light fitting LEDs have a slight glow suggesting there is live leakage from somewhere. Could the wiring between the extractor, light and isolator be wrong?
