Fix my cooker hood!

[Clint]

Hello all,
My cooker hood is playing up! The extractor works fine on all settings but after the light bulbs popping a while back,new bulbs obviously, the lights now don't work!
I've done a Google and a suggestion was to change the control switches which do both fan and lights as the switch could be broken. I did this earlier, just 6 wires in a block connector and a few screws...the fan works but the lights still don't! Tried some new bulbs I had just in case! Also they're halogen type screw in 40w,so not getting an issue with low voltage LED.
What next?

Righto..
Espares list most bits for this, and there doesn't seem to be anything unusual.

Do you have a simple tester or a contactless leccy detector pen even?

Not at home,I can get one in work though not back til Sunday.
Thanks for trying to help.

There is a microswitch listed for it?

Does that work correctly? Probably act's like an interlock when you move it.

This does sound like a wiring thing. I went to one with broken lamp, but it had also melted the wires... A good visual inspection wouldn't go a miss.

I can't see one,perhaps it's up in the chimney section,which is fixed through a section of unit that spans the cupboards either side..typical!
I did check the wires and did cut and restrip an end of one that looked a bit crushed.

With a tester you should be able to follow live, from source, and see where it stops.
