If any of the button on your Hygena extractor don’t work (on/off, light, fan speed 1 and 2) this is the part to replace and fix that issue. This part also replaces the indicator light as well.
To fit this you will need a soldering iron. There are 7 cables to solder in total.
Note this part does not include the buttons that you press on the front of the switches. You can easily remove the buttons from the old part and put them on to this part.
