I'm want to replace all 4 of my old noisy Broan bathroom fans. All the ceilings are finished and unfortunately I have no access from above. The existing fans have 8.5"x8.5" frames mounted to 2 x 8 or bigger joists and all ducting probably 3". I've looked at the PDF installation for the Panasonic WhisperFit and the fan seems to be designed for my situation. Just wondering though if you would have other considerations and recommendations. Thanks

<p>One of the most common <b>bathroom fans</b> is the <b>Broan brand ventilation fan</b>. These fans come in many configurations and variations. Because of the environment that these fans are in and the placement of these fans they will get very dirty over a period of time and will need to be cleaned from time to time. <b>Cleaning bathroom fans </b>can be fairly easy if you have a few tips about how to do it.<br />
<p>To clean the fan the inside of the fan must be accessed first. To get to the inside of the fan the cover must be removed. Most of the covers simply will pull downward and away from the ceiling. There are a couple of springs, one on each side the snap the cover up and hold it in place. On some models there can be a screw that holds the cover. It will be visible right in the center of the cover. If no screw is visible then you can assume that it is a spring type cover. If there is a light in the cover you can remove the plug and the light will come right with the cover.<br>
<p>After pulling the cover down simply squeeze the springs together slightly and the cover will come completely out and you can take it to your sink to wash it. Then take a vacuum or a damp rag and clean the inside of the fan compartment. If you look closely you will see that the fan assembly has a plug that can be pulled and the fan assembly can be removed by either removing a couple of screws or by placing a screw driver between the fan assembly and the side of the box and snapping out the fan assembly.<br>
<p>Once you have the fan assembly out you can then use compressed air, like you use on your computer keyboard, or a damp cloth to clean the fan assembly. The compressed air works the best on the blower wheel and in some cases a small screw driver may be needed to remove caked on dust inside the fins of the fan.<br>
<p>With you vacuum, you can now clean out the rest of the box and even into the vent hose a little bit. Be careful not to destroy the flapper, as that is what stops cold air from being pulled back into your home while the fan is off. Wipe down the box to complete the cleaning.<br>
<p>The fan can now be reassembled by reversing everything and placing it all back as it was before you removed it. Be sure to remember to plug the fan motor back into the socket. The light may also need to be plugged in if you have a light in the cover.<br>
<p>You will now have a nice clean fan again. <br>

Hi -- I just spent a couple of days taking out the old assembly, cleaning all the parts (layers of dust coats) and putting the 9093N back in order to fix the noisy fan. The cold air coming back in is from to the heating and I'd guess the heating element is busted. Yes, you can run it in both airflow modes: ceiling air exhaust and hot air blown to the floor. That said, the noise level on mine hasn't gone down. So I'll look for the replacement assembly. Good luck!
First turn the power to the fan OFF. Take it down from the ceiling by removing the screws holding the cover on. Then remove the screws holding it to the ceiling. Then unscrew the screw caps that twist (connect) the wires from fan motor to the house wiring. Do a general clean up on the fan. Use an old paint brush to get in the hard to get at places. Rotate the fan by hand. If it does not rotate freely, put some oil on the shaft where it goes into the motor, and put some on where the shaft comes out the back. If it still does not rotate freely, buy a replacement and install it.
If you have the old Thermador ceiling type of heater that must be mounted on the ceiling surface there aren't many choices. Only the Broan-Nutone 154 & 157 models. The 154 @ $37 didn't seem to last too long but it's 1/3 the price of the radiant 157 model at about $100+ dollars. The radiant model may last longer
If you are not very handy I don't think I'd tackle this project. There's going to be drywall cutting, backing to install, attic crawling, wiring, ducting to attach, proper insulating. As an electrician I've done this sort of thing in between 1 and 2 hours, depending on how smooth things go. If you find somebody you trust that's done it before who is willing do to it on the side for cash you're looking at $25-$60 for labor. Is it worth it to you?
