Question about Broan-NuTone N-QT9093WH Combination Heater Heater Kitchen Hood

1 Answer

Should I buy a new exhaust fan or try to fix old one?

The fan motor is very loud in this unit. We bought the house six months ago and it seems to be getting worse. We have the same one in the kids' bathroom so I know it isn't supposed to sound this bad. Can I replace just the fan/vent motor or should I just buy a new one? I found one for under $250 in white, ours has the brass ring, but I don't really care about that. I'm thinking if I do replace it I should buy the same one though so I don't need to cut a new whole or do repairs. Any thoughts? I did take off the exterior and look for vibrations, but it seems to be in there sturdy.

    they sell motors for it
    the manual for this vent is clear as day
    what the fan motor p/n is.
    if its blocked or dirty clean the fan
    a fan with junk on one side is imbalanced and will make noise
    a fan blade,,missing cracked or bent will make noise. replace it.
    the motor can be bad. and make noise.

    the vent on top can be blocked making the fan be overloaded and makes noise, clean that.

    here we go, a simple search.

    no lack of fans sold ever.
    buy one put it in, its super easy job.

    in almost every case, no need ever to rip out the whole fan assembly, and pay $300 for the fan and $100 labor.
    just unplug it , unscrew it and replace it.

If the air flow in the duct is restricted, that can cause excess noise also.

NuTone LS100 fan is squiling when it runs. Spinning the fan blade by hand when it isn't running doesn't make any noise. Am I correct in thinking that the motor needs to be replaced?

Sounds like it may actually be the bushing pack inside if the motor. Spinning the blade by hand is not going to spin it fast enough to hear the problem. If the unit is new, I would recommend returning it for exchange of a new unit. If it more than 1yr old, it's out of warranty and will be cheaper to just replace it rather than repairing it.

For less than $100 you can buy a newer, more efficient model. Depending on the size of the room is how should judge what unit to buy. An under sized unit will not pretty much nothing, except make noise and remove some of the steam. Remember to buy a fan with the lowest SONE rating as it will have the highest quality motor housing and best air removal.



Yes and maybe.
If you open unit, usually fan motor is plugged in, and motor is removable with bolts.
The problem is finding new fan that fits same housing without spot-welding and drilling.
I did google image search for "replacement vent fan motors" and results show choices.
For example Nutone:
If you can locate same brand vent at local box store, you can use parts from new one to repair old one without project of replacing fan housing.

20 years ago, motors went to electric repair shop and they rewound the motor.
But today, motors are landfilled or shipped overseas for recycling.
All costs are energy, and right now, cost of re-wind is more than buying new motor, or new vent.

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.

Loud fan noise

The fan noise has two reasons: one is that ice forms around them causing strain on the disk brush in the middle, which wares down the brush causing the fan to go out of balance, this causing the loud whinning and sometimes high pitched squilling. This happens when the unit is six months to a year old. The first thing that is suggested by the manufacturer is to let the unit be unplugged for twenty-four hours, allowing the ice to melt from around the fans. It has been my experience that this is only a short term fix. You can repeat this every other month until the revolutions per minute of the fans is so reduced that they no longer supply enough air ciculation to cool the refrigerator or the freezer. The solution to this problem is to replace these fans about once a year. Unless the noise does not bother you.

Home heating system question

Hello meglong what type of trane model is it? In the service package that was offered to you was one removing the exhaust fan for cleaning and a minor tune up every year? Because normaly the exhuast fans can be cleaned just by blowing out the fan with some air or even a vaccum cleaner.

Loud noise from the freezer side

The problem is a buildup of ice on the plastic housing (the curved plastic bit) in the back of the freezer under the fixed shelf where the icetub goes. The fan behind this plastic housing is hitting the ice when the defrost comes on.

Unplug the fridge, unpack the freezer, remove the four screws in the back, take off the sheetmetal backing and let the fridge thaw. You can remove the plastic piece after a while and get the ice off (be careful not to remove the styrofoam insulation by going too quickly).

Reassemble and you're back in business, for a few months. I'm never buying Samsung again myself.

Loud noise

Got tipped sideways or other in move and the drum is not on the runners.(Felt front and Bogey/rear)... (Some of these you can reposition buy lifting the drum up from the inside and adjust realigning)..

They can make a racket!

QT 100L replacement

Don't worry, you can purchase just the fan from amazon (not entire motor). here: NuTone 0696B000 Motor Assembly for QT100 and QT110 Series Fans. I hope this was helpful. cheers

Noisy fan

We had our house built with the same Nutone fan/light units in all 4 bathrooms. Moved in in 2002. One of the units starting making a loud noise last month. I popped the plasic cover off the light, then carefully pulled out the bulb, then unscrewed the wingnut in the middle. That allowed removal of the light assembly. Then I had access to the blade and motor. I found a lot of dust had collected on the motor and blade. I blew most of it off with compressed air (like what you would use on a computer), then used an electronic cleaner on the motor, then wiped off the blade and motor with a clean cloth.

I then crossed my fingers and turned on the fan.... It worked! It was quiet again. I waited a week before posting this. The fan is used every day. It is still quiet today.

If it ever needs replacing, I saw that Nutone sells the motor alone for about $22, that's a lot better than replacing the whole unit for around $70.
