How do you change a bathroom exhaust fan?

The ones we currently have turn on but do not suck out the steam. Now there is mildew on the ceiling again!!

    Doing that involves breakers, wiring, wire nuts, sizing new fan to bathroom. Your old exhaust fan could be either old and not working correctly or undersized to your bathroom or needs. If you are not handy or experienced with electrical wiring, find a friend who is or there are some excellent books and videos (places like youtube) out there to show you how. You will need to figure out which breaker controls your exhaust fan and that will need to be off - this step isn't optional, I don't care if the fan is turned off at the wall switch, throw the breaker to the off position so there isn't a chance of getting shocked! You'll need the new exhaust fan, wire nuts, probably a screwdriver (this is for removal and installation of the fan as well as the ground wire). It isn't a hard job but you really need to be comfortable and thorough and safe doing this.

    Sounds like your fans may not be vented outside. That is the first thing to correct. Second is how long do you leave the fan on after your shower? You should not expect the fan to remove all of the moisture if you turn it off at the same time you turn the water off. As for replacement, is the top of the fan accessible? If there is a finished floor above replacement may be a big job.

    It involves taking out the old one and putting in a new one. The problem you will have is the box will be a different size than the new one. Someone will have to remove the box that holds the fan in place and put in the new one. go to Lowe's or Home Depot and talk to them. Hopefully you can find the same fan and just replace the motor.
