        Bathroom fan install help Sign In/Join 
        posted
        I'm replacing an older, inexpensive bathroom fan with an upgraded Panasonic model. The old fan had one live, neutral, and ground. Those controlled both fan and light.

        The new Panasonic has one ground. It has a separate live and neutral for the fan, and one live wire each for the light and nightlight. There is only one shared neutral for light and nightlight.

        My incoming wiring from the old fan is one ground, one neutral, and one live, off a single wall switch. That's it.

        If I want my new fan to run just like the old one — all lights and fan on when the switch is on, all lights and fan off when the switch is off — how can I safely depart from the instructions on the installation manual that assume there's an incoming wire to meet each corresponding wire on the fan?

        To control them all by one switch join all the hots together and join all the neutrals together. Now one switch will turn the fan and light on at the same time. I'd probably just leave the night light out of the equation.

        One thing though is the fan controlled automatically by a humidistat? If it is the fan really should be installed with a hot all the time and let the humidistat control it.


        General Disclaimer

        Any advice given here is general in nature and is not necessarily valid for your given area. If in doubt check with your local codes enforcement department for what is required when doing electrical, plumbing or structural work on your house. Permits may or may not be required in your area and home owners may not be able to DIY some tasks. I have no way of knowing if you have the skills needed to complete the tasks you are asking about, when in doubt seek professional assistance.

        My advice may be worth exactly what you pay me for it. :-) For the record I did not stay in a Holiday Inn Express last night.
