The appliance: ============== Hotpoint cooker hood/fan Mod

Customer Question

The appliance:
==============
Hotpoint cooker hood/fan
Mod HXV9K Cod 74094
S/N *********
Indesit Company
The problem:
============
Just stopped working.
No lamps on anywhere, no sign if life, just like a total loss of power.
What I have done:
================
I have checked the power supply is OK.
Instructions, unhelpfully say:
"If the hood has turned off during normal functioning:
Check that:
- The power has not been disconnected.
- the omnipolar disconnection device has not tripped."
I cannot see anything that looks like an "omnipolar disconnection device". There is no mention of it anywhere else in the instructions, nor can I see anything on the tiny internal wiring diagram next to the model info plate.
I expect to find a reset button somewhere along the route of the incoming power cable, but I cannot see anything likely-looking.
Before I start tearing it apart, a job that will involve removing the heavy, hinged black cover, is there something simple I can do to locate the elusive
"omnipolar disconnection device".

Hi I am sorry to hear that. do you have a meter for testing?
You will need that for this task.
I will help you with this.
You will need to access the main control area inside the fan unit.
This may be a loose connection or a fuse but all that would be inside the unit.
If there is no user replaceable fuse you can find please let me know.

I have a multimeter thanks.

I think the main control area looks like a black rectangular box about 6 X 8 in in size - yes?

I will have a look inside, but you won't hear from me again for a while - it's at my step-son's house.

Hi John,
yes thats it;-)
Im here as you need me.
Customer: replied 2 years ago.

Opened the main control unit.
No obvious loose connections.
Verified that mains voltage is arriving OK.
One small, low-value fuse on the board, but it's good.
No other obvious breakers/fuses - not much on the board at all, in fact.
Tried measuring what looked like some of the output pins, but no voltage detected on any of them.
Can send you a picture if that would help.

Do we start suspecting the control panel? It's a touch panel - horrible!

John.

Expert:  Michael replied 2 years ago.
Hi John, make sure your switches work and provide continuity to the board as well.
If thats all ok, then you will unfortunately need a new board ;-(
They don't sell parts for the boards anymore.
Just complete circuit boards I'm afraid.
The best place to get the board is : http://www.hotpoint-spares.co.uk/
Its best to call them on this part. and I have included their phone info for your convenience:Call 01489 782 492
Please rate my service to you, kindly before closing this page you will still have access to me and you can contact me anytime
simply by replying to this message at no additional cost;-)
Thank you John and have a great day!

Hello John, my name is George.. Just one thing to check before ordering your PCB as Michael has diagnosed.

Please disconnect your appliance from the mains and using your multimeter, check the continuity from the cable end or plug to the power input on the PCB for both the Neutral and the Live cables

Don't assume that since there is a live, there is also a completed neutral

regards
Expert:  Michael replied 2 years ago.
Good morning, how did things go with that test?
If that was ok please order that PC board to fix this issue;-)
