The fan and light switch are not working

Yes it is likely to be the switch. I have one of these as well. Remove the switch and test it with a multimeter.

Question edited for clarity. This appears to Broan rather than Braun. Added full model name.

This answer on Fixya hints that the original boards were faulty. I thought he was from Broan, but it sounds like he is a repairer.

The fan light switch blinks when it is time to clean the filter. Clean the filter, then press and hold the switch for 3 seconds to reset it.

check fan switch if its fine then check motor

It sounds like your switch is getting stuck internally. It most likely needs to be replaced.

Hope this helps you somewhat, please post back if you need more help.

You are tiring to hook up a 3 way switch. It is not that hare. just look at the diagram on link below.

online.com/3waydiagram.htm">http://www.electrical-online.com/3waydiagram.htm

You can remove it and bench test it by applying 120 volts to the fan leads. Do you know how to do this -- it can be dangerous if not done properly.

You can also use a voltmeter to measure resistance and check continuity of the motor coils.

The Black 120vac Line In wire goes into "L". The Black wire goes into "2". The Red Wire goes into "3". When you install the switch, the Red and Black wires will be on top of the switch.

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.

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