SOURCE: QT 100L replacement

Forget it. I also had the same problem with the QT100L. Cannot buy this unit and the replacement unit is the LS100L by Nutone/Broan. Good news: it is more powerful 110CFM and the housing is the same size. Bad news, the motor assy is completely different and it cannot be mounted in the existing housing. To install the new unit, you will need to cut the ceiling around the fan housing and install the new housing and wire it as well. Be aware that the wiring comes into the housing 180 degrees from the old QT100L unit. That means I hope you have enough romex to reach the hole. My advice is to get another unit from any other company because the quality sucks. It will be as much work to install any other brand as the LS100L.

SOURCE: Replace motor in Broan 678 bathroom fan

I ran into the same problem, Lowe's carries Broan exhaust vents. They had both a replacement motor for all generations of 678 fans for $18, and they also had the latest generation of the complete unit for $40. I bought the complete unit, which included the fan I needed. Just unbolted it from the new bracket and bolted it to the old one. The new light housing, trim piece, and lens also interchanged. The existing one was old and yellowed, so this made for a huge improvement. All done from in the living space as well.

SOURCE: Problems with exhaust fan NuTone Model LS 100SE

The C-frame motor for LS100SE (P/N 62345) is no longer manufactured, and no replacement is specified. I checked with Nutone customer service if the motor for LS100 (P/N 89169) will work. They said the blower housing is the same between the units, so it should work mechanically, but the plug configuration is different requiring some electrical changes.

SOURCE: We have a Broan/Nutone 763RLN Ceiling Fan/Light in need of cleani

The grille is held in place by the reflector. The reflector is hidden by the the lens. The first step is to remove the lens, then you will remove the light bulb. You will see one wing nut above the light socket. If you unscrew that the reflector and the grille should come down. The replacement motor assembly for the 763 RLN is the S0503B000, if you are looking for a little more power you could also purchase the S0504B000

Our exhaust fan is really noisy. Nutone QT 100N-B model. Where can we purchase a new one?

This model has been discontinued but replacement motor assemblies are available. There is no off the shelf model that will fit in the existing housing. If you do not want to replace the housing then the motor assembly is the way to go.

When it is windy outside the flap on my exhaust fan flaps open and shut. Is there a problem in the way the fan was installed?

Not likely, Just a condition of the location of the vent and the wind direction.Putting a secondary larger hood over the outside exposure will sometimes help alleviate this.
