Question about Broan-NuTone Allure III QS330SS Kitchen Hood

2 Answers

Fan and lights come on and go off all day long on their own

Everything was working fine but all of a sudden the fan started coming 'on" on its own and runs and then shuts off on its own and this keeps happening continuously. The lights will do the same but not as often. They "blink" rather than staying on. When the fan comes on and runs I am not able to turn it off. It has a mind of its own. This has never happened before and started for no apparent reason.

We installed our Broan-Allure range hood about ten years ago. On three seperate occasions since, the fan has randomly turned on and none of the control buttons would turn it off. After a while it turns itself off. During those same times, when you turned the lights on, they would blink before finally staying on. On each occasion, I have removed the screens and metal underpieces to gain access to the circut board. Once you can see the circut board, remove and replace the 3 Amp fuse that is mounted on the board. (Radio Shack part # 270-1054)...even if the fuse looks good, replace it. Each time this has work for about three years, then it acts up again..

    We may have a different model (Braun allure) but I dont see how to remove anything to access a circuit board?

Light button stopped working

Hello Becky,

I Have a lot of questions and it may be easier to call me. Don't worry I won't try to sell you anything!! My name is Jack Jr and I am a ceiling fan tech and troubleshoot / work on fans all day. I can be reached toll-free at Fan Man Lighting (1-866-600-3267). Some things I will ask you though is does the little indicator light on the transmitter come on when you press the light button? I would start by switching off the transmitter (the slide switch you mention), tugging the light pull chain, restoring power (with the slide switch) and then trying the light again. If this does not work I would like to know approximately how old is the fan? How many dipswitches does your wireless system use?. Where is the Receiver located in the fan? Don't worry, I can walk you through each of these questions and make educated guesses if you do not know. Also I will have some trouble shooting tips. Stay warm!
