Question about Broan-NuTone Allure III QS330SS Kitchen Hood

1 Answer

Broan Allure QS3

Install was easy, but it is not functioning correctly. With no buttons pushed, the fan runs at extreme low speed. I can turn it off only by pushing the boost button, Lights do not work. Pushing button/ speed 1 produces a higher speed, but button 2 slows down fan and button 3 slows the fan down even more. Broan tech support sent me a new control board, but that did not solve problem (same symptoms). I do not have a wiring diagram, so I do not know if the wire harness is misswired. Maybe a transformer is bad. Suggestions?

    The fan won't turn off. I have to press the "1" button to shut it down, but it doesn't entirely shut down--slight fan movement remains. The hood is an Allure QS3. I have pressed the buttons on and off but nothing works except pressing button"1" on.

    I have a similar problem, the right light does not work. I have changed the brand new bulb with another. I took the filters out and I can see 1 wire that has a couple of wires leqading into it, and a black end connected to nothing. I am sure it is supposed to, but cant find where to connect it. Any ideas?

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

Broan Allure range hood fan will not turn off, no matter which button is pushed.
The fan switch contacts are probably welded together or the actuator mechanism is broken. Your best bet is to replace the fan switch, probably with a similar type having a higher current rating so the new one won't also be susceptible to contact welding. If you have an industrial electrical supply dealer or electronic surplus parts store in your area, those would be good places to look for a replacement.

I have QS3 series range hood. Fans are not working though lights are okay. When I click the fan buttons it does turn green, with clicking sound however fan doesn't turn on. Please advice
Hi,
Sometimes they can be cleaned and oiled and they will work again...
Cleaning the grease and dust with out ruining the motor is the tricky part...
Take the unit apart as much as possible...spray down the fan part with a degreaser or strong cleaner...let it soak and they spray it down with water to rinse it off...
Then work a few drops of light motor oil into the motor by proping up the fan so that the oil will run down the shaft and into the motor...

then get it running smoothly by working it by hand...

Put it all back together and it should work again...

Check that you have not accidentaly switched the wall socket off in the cupboard above the rangehood. The slide switch could also be faulty.

Broan Allure II
I called Broan technical support. They said that they had heard of this issue before, but that there was no recall. I suggested that it was a frequent enough problem for it to come up 3 times in 12 mo. on one website. She was underimpressed with this statistic and said that they sell millions of them. She would not disclose the name of their supplier so that I could get some information on the actual controller unit. She did not seemed as pained as I was by having to part with $130 for a new controller.
