Issue with hob extractor fan

zyper

Hi

A few weeks ago the lightbulb went out on our extractor hob with a loud bang. It even short the fuse in the fuse box. Changing the lightbulb didn't work & I quickly found the fan had gone too (have had the light go off once before & it was simply a case of changing the buln but, not this time, the whole thing had stopped working). I checked a few thing myself & got the guy eho fitted it with the rest of the kitchen a coupled of years back to have a look.

We checked the plug fuse, the fuse on the fan, the wiring in plugs & fan &all seems OK. The only issue neither of us had come across before is a little unit within the fan (might be a transformer?) with these details: Lifosa mkp F1M 40040PG, 4mf +/- 5%, 425/475v, EN 60141-1. I've looked on the internet to see the price if it was reasonable to order & change myself & see if that works, otherwise we would have to get an electrician in.

Any thoughts/ideas what it might be?

PS hood was bought from b&q but they do not keep any spare parts for the units!

It looks like this but like I said earlier I'm just guessing this might be faulty as we've exhausted all other possibilities we're familar with (neither of us are proper leccys but we know a decent amount to solve simple to mid level issues)

Is the pcb the image you posted or the one I posted? I assume you can get that (pcb) from a diy store & can replace yourself or would you need an electrician to do the job?

Thanks

I would say the image you posted was a capacitor , they are readily available from Maplins or ebay

Sorry to keep coming back to this, but you think it will be the pcb rather than the capacitor then that might be the issue? if pcb, would i need to get an electrician or is it somget & ethin i can do myself? thanks
