Hi bathroom light and fan stopped workimg for no reason changed fan as I thought it could be faulty and visualy could do with upgrade but with no joy so I went on to change the light pull switch still with no joy all connections are sound any ideas help

Have you tested for both power and neutral reachingh the unit? You should be also able to check for power entering the switch box by putting your probe on the incoming black wire and the box, if metal.

Most folks come to the desk for help without hiring a pro. If you read the posts at AMHD and watch for folks who are either an expert or highly rated you will get the help you need.

Check all GFI outlets. Sounds like a GFI tripped some where.

I've got the same problem... the plugs works but I reset the GFCI anyway. The lights and fan still won't turn on. The fan is also connected to the whole house circulation switch but that won't turn it on either.
