All lights out on Faber Axia cooker hood

Without the MODEL Number... and the 12v GU4 lamp... I am going to HAZARD A GUESS that your lighting has an internal TRANSFORMER... (most likely)...

But there are less expensive things to check first

Since this is now a GLOBAL SITE you will have to disclose your Line power... (USA: average household range hood = 120V 60 cycle AC current)...

ERGO:
transformer is a 120v to 12volt output (live measurement)

For walk up TROUBLE SHOOTING
"Multi-meters" are a must...

Opening assumption
THAT YOUR NEW BULBS are good... is understandable... but possibly wrong (I'm just saying).

Power OFF
- Verify bulb continuity
- Verify switch operability

Happy hunting

Just look this youtube video, and it can't be more clear.
Don't forget to unplug the hood, or switch it of. Although the halogen lamps are only 12 volt. In the hood are dangerous voltages. How to replace cooker hood halogen bulb or lamp

i need the same part. where did you order it from? thanks.

Here is how I fix this problem in case someon is still looking for an answer: 1. Turn power to hood off at electric panel 2. Remove light diffusers - these are the round glasses under hood covering the light bulbs. Turn the light diffuser counter clock wise to remove 3. Remove the burned out light bulbs 4. Install the new light bulbs

Your voltage regulator is faulty. Alowing too much voltage to blow your bulb, unless the bulb is the wrong voltage of course.

the switch may be Faulty the fan and light are on parallel circuits.

The more I worked with it, the more I discovered that the real problem was that a screw was not all the way screwed in and it was preventing the panel from sliding. Another problem I may have is finding the glass covered halogen bulb.

take the bulb out and bring it with you to store and see if you can find one the same . DIY stores have tons of types.Joe
