Question about Broan-NuTone Allure III QS330SS Kitchen Hood

3 Answers

Random fan speeds and light levels???

When in operation my Allure III range hood fan will sometimes "toggle" between the selected fan speed and the next/higher fan speed. In addition to this sometimes the light intensity will "toggle" from the selected level to the next/lower light level. This is quite a sight when this starts in the midst of cooking and the fan and the lights start toggling all together. It's like having a ghost in the thing. I have found that by selecting the highest fan speed "B" and the highest light level the toggling will stop.

On rare ocations the light level will toggle if the range lights are left on without the fan in operation, however I,ve only experiance this a couple of times, unlike the previous issue which happens about 25 to 30% of the time the the range hood is used.

I'm thinking that the issue may be related to the "Heat Sentry System" feature of this range hood, however i'm not 100% sure of that. The control assembly (part # R111653) most likely either needs to be completely replaced or and least have some circuit level trouble shooting done and some components replaced.

Would anyone have a solution to this issue or a schematice for the controler assembly (# R111653).

Thanks,

Alan

    I have had a Braun QS3 Range hood since they first came out and it has been nothing but trouble. First it stopped working within the guarantee, so they sent someone out who added a new circuit board to the existing board. Then after the warranty expired, they want $163.88 to replace the board (Part # r111653). The board still works if I open it up and pull it down a bit, but normally the lights and the fan don't work until the stove heats up to a certain temperature, exactly what temperature that is I can't say.

    I have called Braun tech support over the years and they basically say that this happens if you don't ALWAYS use the fan when you are using the stove. Moisture gets up into the board, etc. Sounds like a design flaw to me!

    My hood fan does the same thing. I will buy a new unit before spending money on a new circuit board for this piece of ****.

    Just installed a Broan Allure QS 236SS. The fan will not turn off. The fan came on as soon as I turned the power on. Pressing the fan speed buttons 2 and 3 trun up the fan speed. The fan seems to be running on speed 1. Nothing I do turns the fan off. The lights work properly.

I have the same problem for this piece of ****. Everytime we use the stove without the fan, the lights start turning on and off, even if we haven't turned the lights on.

I have the same issue. Have to reset the breaker to make it stop. Bet it is a bad controller (design fault).

Noisy fan or motor?


HI. The most common issue here will be with a loose motor shaft. This is the part that the fan blades are mounted on. When this occurs, the looseness will cause the motor, and shaft to wobble, thus, causing this noise you here at high speeds. The wobble is less violent during the slower speeds, so it is not loud, in this case.

The second issue will be a warped fan blade. This will cause the fan to rub against the shroud, thus, creating the noise, as well.

If the shaft is loose, or bent, the entire motor will need to be replaced. Now, if the fan blade is warped, you can, simply, unscrew the blade from the shaft, and replace it(on most model)

Range vent damper noise


Check to make sure that the installer completely untaped the damper when he installed it. It needs to be able to move freely.

Changing fuse on Nutone Allure Ws2


Hi Mertl, I sure hope you found the solution since, but I am posting the answer for other people like me (and you) who need to find it !

The service manual says:

To replace the fuse:
1. Disconnect power at service entrance.
2. Remove filters, bottom panel, light wire harness, and air chute.

The fuse is actually right behind the fan controls, so to access it you need to disassemble everything that's in the way.

BTW, for anyone wondering if it's the fuse that's faulty, here's a clue:

If the fuse has opened (blown), the green fan-level indicators
will operate properly when the fan buttons/switches are pressed
- but the fan and lights will not turn on.

The fuse is a 5 x 20 mm, 10 Amp, Fast-Acting, 125V (min.).

Good luck all !

Had same problem & fuse fixed it.
Before buying a new control board (approx $160), check the 3 amp fuse located on the inside of the vent on the control board. You have to take the light/bottom housing & black plastic air chute off to see control board/fuse.

Broan Allure QS3


Hello,

The Problem is the wiring. Take the 2 screws retaining the metal plaque off underneath the filters. You will see the wires leaving the motor going into a "molex" plastic connector which connects two another set of wires going to the control board. Check to see if the wiring colors match from side to side of plastic connector. Ive only seen it happen once but it was exactly that. I do service calls for broan & Nutone
