Kitchen Extractor

telsokari

Hi there,

my kitchen extractor after 3 years of working perfectly has all of a sudden stopped.

we recently had the switch changed from a plastic white one to a chrome one and then 3-4 weeks later when switching on the extractor while cooking it just stopped working.

i changed the fuse in the spur but that made no difference.

the electrics in the flat are only 3 years old and there is a trip switch, but that didnt set when the extractor went.

My question is, is the extractor salvagable or is it dead and need replacing?

Thanks

Have you tried putting the old switch back to see if it works with that one.

Was the fuse blown? Was the new one a dud?

No idea. You don't actually know yet of its the fan that is dead. Think you might need to fault find a little more before float testing the fan TBH.

Does the fan need cleaning perchance after three years useage?

Can you check inside the new switch to see if there are any loose connections? The fact that it stopped working so soon after the switch was changed suggests it might be this

Make sure you switch off the power first before opening the switch!

The new fuse definitely works as i took it from another Spur and put it back.

The old switch was thrown away when it was changed by the electrician

in terms of cleaning, i don't think thats the issue as the light doesn;t work either.

when it went, there was some sort of "pop" type noise

Not sure if this is the same thing or not but one of the lamps blew on our extractor a couple of weeks back. (It was you're description of the 'pop' type noise that made me reply.) Within one day the second lamp started working only intermittently. I went and bought two new lamps (light bulbs) from a local supplier and changed both on the extractor. It all now works fine. Total cost under £3.50.

Others may be able to advise whether extractors commonly have internal 'systems' that will close all down if one part blows?

By the way, the lamp that blew first had obvious black/burn/blow damage on it seen once removed. The second didn't show anything but I changed both anyway.

Hope that may be of some help,

I would isolate the supply at the consumer unit, open up the enclosure that the fan/cooker hood sits in and find the point where its flexible cable is hooked up to the supply lead , and disconnect it

With a length of mains flex, I'd connect one end to the extractor, the other to a standard 3-pin mains plug, then plug it into the mains and try it that way. If it works fine, you know the problem is somewhere between the consumer unit and the fan.

If it blows the fuse in the plug, you know the fan is definitely faulty.

If it doesn't work at all, you know it needs replacement.

I'd also be using a multimeter to check for mains voltage at the cable next to the fan with the power restored and the wall switch on.
