Question about Broan-NuTone Allure III QS330SS Kitchen Hood

1 Answer

I can switch on lights and fan, but then they switch off

The lights and fan work initially, but after a short while everything shuts down.  A few minutes later, it works again.  Seems like a thermal problem.  What part should I replace most likely?  The control panel, or one of the transformers?

It could be either. Usually i would say its the control board, but its very possible that its the transformer. I would start with that, the trans=25$ then control board = 110$
Its the small transformer (blue/yellow/black/white) wires coming out of it.

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...

No power to the fan or lights. Checked the


You're saying fan (singular) and lights (plural)? Does this fan and these lights work off of one switch? If so, then it's probably a bad switch. You can check this by turning off the circuit breaker. Remove the switch from the wall, and put the two wires going to that switch together. Make sure to use a wire nut, or tape to keep these wires together without touching and grounding anything. Make sure these wires are clear of anyone or anything, and then go back and turn on the circuit breaker. If the lights and fan go back on, then it's a bad switch. This is what it sounds like. So now, you can turn the cir. brkr back off - replace the switch, and then after everything is secure and the switch is in the off position - you can turn the cir. brkr back on again. Then go back into the kitchen and turn the switch on again to reaffirm that everything is back in working order. If for some reason this doesn't work, feel free to contact me again. Good Luck!  Jim

30" viking downdraft goes up & down fan runs and will not responed when pushing on touch panel


After 11 years of use, the same problem just happen a few days ago - fan keeps running, doesn't respond to the on/off switch. Also cannot reset filter alert. As far as I can tell the entire switch panel isn't working. Or worse, shorted out. Might have to replace the ribbon and some switches.
For example the switches can be found at AllVikingParts.com For example --> http://www.allvikingparts.com/Button_Switch_Assy_p/pv300182.htm
There's a another thread on this forum: http://www.fixya.com/support/t410261-viking_downdraft_ventilator_electrical
I'll post the exact solution as soon as I have it figured out completely.

Fan turns on and off since turning hood light on a few days ago


If it is a Broan, there is a delay button that was also depressed. It will turn the fans off after a few minutes. If not, then you're shorted out either in the control panel or the wiring in the range hood.
