We have a neff cooker hood - approx 6 years old, D91T7N0GB

Resolved Question:

Hello - we have a neff cooker hood - approx 6 years old, D91T7N0GB /01 FD 8608 000026###-##-####HBD-FX70-8 and there is something wrong with the internal electronics for the lights. The extractor is working fine, but when we turn on the light - from either side - one light briefly comes on and then turns itself off - we think there might be a faulty dimmer switch or something? Can you advise on how best to proceed as at the moment our only option seems to be a £160 fixed price call out fee which seems expensive to fix a light!

Hi

To be honest if you are having problems with the light on this its more likely the transformer rather then the control board.

As the lights on these are low voltage so they have a transformer which drops the voltage down for the lights to work. If this fails then the lights dont work in there.

So its more then likely the transformer at fault here rather then the control board itself. If you remove the chimney section of the hood you will see the transformer near the control board. Try and replace this first and see how it goes from there. The part is £50 and if you want the part number its 00493608.

If you need anymore info just get back to me.

thanks for the reply :)

My husband says: Given that the light comes briefly on, gets overly bright and then the whole thing shuts itself off, do you still think it is the transformer?

many thanks

Yes it can still be the transformer at fault.

The way to test this is access the transformer and there you will see 2 wires going into it from the control board and 2 wires comming out going to the bulbs.

Check the wires going in with a multi meter and see if theres a constant 230v there when the light is turned on. If there is then the transformer is the fault. But if there isnt the the control board is faulty.

But as the light does come on then there will be the 230v going to it so as i said its more likely to be the transformer then the control board here.
