If your bathroom exhaust fan is making a weird vibrating noise or just will not turn on and vent out the moisture, then here is how to fix it. When performing bathroom vent fan replacement installation, you do not need to remove the complete vent assembly. You only need to remove the fan motor housing assembly. You can then look online or take the fan housing assembly to your local home improvement store (Lowe’s, Home Depot, ACE) and match it up with a replacement fan motor assembly. These fan replacement motors are inexpensive at about $20 dollars each. They are super easy to replace, you just have to make sure you match it up with the correct replacement motor that will fit in your vent housing assembly.

NOTE: Before replacing the fan motor, make sure the plastic cover is tight and not creating the vibrating noise because it is loose. Also, there may be a weird noise coming from inside the vent because there is so much dust and dirt covering the moving parts. At this point you can simply clean the dust off of the fan blades and surrounding area. Clean everything out using a wand style vacuum cleaner and then test to see if the noise has stopped. You can also remove the fan motor assembly (see below for how to remove) and plug the fan motor into another power outlet in the house. This is to see if it is turning properly. You can also add a few drops of oil on the fan motor shaft if it has seized up. Once you have done everything you possibly can without replacing anything, put everything back together and test to see if it is working properly. If so, it was only dirty and replacing the fan motor is not necessary. If it still does not work properly, then follow the instructions below to replace it.

As many other sites note, fan motors are very similar across a number of brands. You do need to watch for spline length and fan type. I found this unit works with a very old, discontinued vent fan by Air-o Fan – a fan unit from the 1970's and labeled as 605 for a 600 unit. However, one required change – the fan goes CW and not CCW. Happily, this is very easy to change: just remove the 2 long screws holding the motor ends together, move the pieces so it face the opposite direction and reinstall the screws. Voila, CW. Otherwise, it fit perfectly! Agree that the air volume isn't wonderful, but it's decent and saved ripping out the ceiling of the bathroom for our discontinued fan model.

If your bathroom vent fan is making a vibrating noise, stops running or doesn’t turn on, it may be time to replace it. Most of the time the small exhaust fan motor will go bad and need to be replaced. The vent fan in your bathroom works very hard as it has to deal with heavy moisture, cold, heat, chemicals in the air, and dust. These conditions can make the fan blade impeller motor freeze up or short out. Most bathroom venting exhaust fans will last many years depending on moisture conditions. Usually these exhaust vents are installed in the bathroom ceiling and are easy to remove and replace.

If your bathroom fan is dead, here’s some good news: You don’t have to tear out the entire unit. Even if you fan is decades old, chances are you can get a replacement motor. Although a new motor costs about the same as a new fan, replacement saves time and trouble. You don’t have to cut into the ceiling, crawl around your attic or get up on your roof. It usually takes less than an hour.

Bath fans vary in design, but motor replacement requires the same basic steps, no matter which brand or model you have. Turn off the power to the fan at the main breaker panel. Then unplug the fan and remove the motor plate (Photo 2). Some motor plates release by pressing or prying on the side of the fan housing. Others are secured with a screw or two.

Step 6. Take the fan motor assembly to your local home improvement store and match it up. It is recommended to also look online for the company who makes your bathroom vent such as Broan, NuTone, Craftmade, Panasonic, Delta, Air King, Progress, Fan Tech, etc. Search for the exact manufacturer replacement to make sure it is still available. There are Universal bathroom fan replacement motors that will fit in your existing bathroom vent assembly.

Step 5. Turn the motor housing clockwise and pull downward to remove the complete fan motor assembly. NOTE: Some fan motor assemblies will need to be turned, pulled, or completely unscrewed to be removed. Watch out for dust falling in your eyes as the fan will usually be caked with it.

The box at Lowes for this model (BP27) shows that it also fits Broan model #688 – A through E. As you can see from this website above Broan does not list this model. It fits and runs just like the old motor, however, I am not convinced that the fan blades (new in the box) are operating as efficiently as the original fan which is similar but has a sealed top and is a bit thicker. The shaft spline is different so the old fan blade won't fit. It does run as quiet as the original equipment. Gave it three stars as it is worth a try at only $15+/- and may work better in other Broan models. Would have liked to use the old fan blades though.

Before you can remove the motor from the plate, you have to get the blower off the motor’s shaft. This is often the toughest part of the whole project. An older metal blower might be fastened with a screw. Plastic blowers usually aren’t fastened at all, but simply slide off the shaft. Either way, removal may require some hard prying and pulling. If you wreck the blower while removing it, don’t worry. You can order a replacement at little cost. To install the new motor, simply reverse the removal process.

Installation and motor are great. Replacement fan blade moves very little air. Simply put toilet paper infront of grill and it is easy to test the air flow, the TP barely stays up against the grill, really, seriously.

If you don’t have a cap on your roof like the one shown in Photo 2, chances are your bath fan vents into the attic. Running a new duct up through the roof isn’t a complex job, but you will have to work in the attic and on the roof. Since you’re doing all that work anyway, consider replacing the fan.

When there’s an attic above the bathroom, some installers take a shortcut: Instead of running the duct through the roof, they end the duct inside the attic. The result is that the fan fills the attic with moist air. That moisture feeds wood rot. In winter, frost forms in the attic and as the frost melts, water can damage the ceilings below.

When the fan is first powered on, it runs very quiet. After it has been running for 1 minute or 2, it becomes very loud. It is like running a air compressor in the bathroom. This is my second unit. The first unit, I thought it was just a defected unit and I went to store to exchange a new one. The new unit has same problem. I even noticed recently that it stopped for a few seconds, then re-start on its own.

View Heaters It’s quite simple. You may use some rooms only briefly, such as the bathroom, as you get ready for work in the morning. Heating the entire home for this purpose is pointless. Instead, opt for spot heating, which will effectively heat the area you need – when you need it.
