I have a bathroom Broan 504/505 vent fan. This model just stopped working. I have power to the unit but for some reason it wont work. I pulled the fan plug from the fan housing & used an extension cord from the fan itself to the wall and it works. I checked the power to the fan housing socket plugin and get 110 volts. I plugged a lamp light into the fan unit socket and it works. For some reason if you plug the fan plug into the fan socket, they won't work together. Any Ideas?

<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> <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> <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> <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> <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> <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> <br> <p>You will now have a nice clean fan again. <br> <p> <br> <p>If you want to <b>replace the fan</B> because it is broken worn out or noisy you can often <b>buy replacement bathroom fan parts</B> or even a new fan that will fit in the same box.
