Question about Broan-NuTone Allure II QS230SS Kitchen Hood

4 Answers

Broan Allure II

I have a Broan Allure range hood. It's 5 years old. Recently the bulbs went out, a few weeks apart. My wife said it made a big flicker and blew, now upon installing the new bulbs, there is no control over the lights - no on/off and no dimming function. Any ideas? Everything else works fine (fan on/off and multiple speeds)

    I have a similar problem, one bulb blew, wife said that was a loud popping when it happend, replaced the bulb, now I can't turn the lights off, and the #3 settting on my fan isn't working.

    Same thing happened to ours--right bulb blew, and now the light is stuck on the highest setting. Fan still works, however....

    I opened it up and banged what I supposed were the relays (the black cubes on the right of the controller), but that didn't wake anything up.

    Same thing happened to mine. The right bulb blew so I replaced it and the light wouldn't work. The left one was usable until that one went as well and now neither work, although; I have never had an issue with the fan. As my hood was still under warranty, the company sent me a new controller and guess what? I replaced the control unit and the lights still don't work. So don't waste your money purchasing a new control unit. I still haven't found out what's wrong with the lights, but I am going to attempt replacing the light sockets (waaay cheaper than purchasing a control unit), and if that doesn't work; I'll be purchasing a new hood and you can bet that it won't be a Broan.

    Same problem on my Allure.

    The lights or Fan go crazy and I have to throw the breaker.

    There is a fault in the design of the controller (null state in the statemachine)

    I have the Allure II also. Mine is less than 2 years old. Within 3 months of install it just died. DOA. So discovering there is a board that basically controls the light and fan I removed it. I called Nutone regarding them sending me a new one on their dime. $154 bucks BTW. They said to cycle the power. Well it worked for about a year and a half.
    It just died again tonight. Cycled the power 3 times to get to come back. Still no go.
    I will be calling Nutone to get them cover the cost of a new one. I would pony up $20-30 for the repair but 154 plus taxes and shipping is a rip off. Stay tuned for the results.

    NO Lights and No Fan - all went out at once - the two halogen lights were less than a month old. Unit is about 7 years old - 3 speed fan type

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.

    Dear Piece o' Junk--

    Both of those lights run off the same line, so it'd be hard to have one go out without the other, unless it's a socket problem. It gets pretty greasy in there, so maybe a little alcohol could clean up the connection.

    I'm currently screwing and unscrewing the lightbulbs when I need light or not, but if you have an extra control board, I'd be happy to buy it off you for $15 if it works (granted the controller costs $100, but an oven mitt to unscrew the searing hot lightbulb only costs $5, so the convenience is worth about $10!). Let me know if you're interested, [email protected]



Had a ghost operating the fan; would start at any time, change speed on its own... So I took the dawm thing apart to see what was underneat, 10 screws to remove quite easy.

Did a "reset": disconnected the electric board connectors (there are 2 connectors located in the front part of the fan right behind the control buttons. Just pull the connectors and reconnect them a few seconds after, though you achieve similar results from the electric box, turning off the braker for a few seconds. So far so good, the exorcism seems to work !

42" Allure II Broan Range Hood I put a new bulb to replace

Get two new bulbs and install them. These bulbs are exposed to a lot of heat above the stove and the filaments get brittle. I suspect that the filament on the bulb that still worked broke when you were screwing it out or back in. good luck. please rate my answer. thanks noreen.

Can not get halogen bulb out of my kennmore elite range hood

You will have to do the following steps.

1. remove filters
2. Unscrew 2 screws retaining metal plate under the filters.
3. Now you must remove the whole light panel. 5 screws in all, three under the front lip and two at both back ends of the same panel.
4.You now unhook the light wires (plastic connector with two wires)

Now you have the whole pnale in your hands. Unclip the socket of "problem side" and unscrew the socket from the bulb. Re-do steps

My broan allure turns on by itself

Isn't it suppose to turn on automatically? The broan has a heat sensor!

Broan Allure QS2 Range Hood

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 II range hood

Did you ever find out what blew the fuse originally? Do the lights have a dimmer feature on them? If so, the reostsat may be bad, or the switch that controls the light intensity, 1,2,3. ect. Something caused the fuse to blow, maybe a wire on the bulb or switch somewhere.
