al_stu Posted February 23, 2015 Share Posted February 23, 2015 Ok so a while ago a switched on the cooked head and the light went pop, pretty big pop. Fan stopped working as wellAh me thinks, that sounds like a fuse has just gone.Changed the bulb - nothing.Changed the fuse in the plug (looked fine) - nothingNow I've taken the whole damn thing apart looking to see if I've missed a 'hidden' fuse anywhere. Buggered if I can see a problem. Anyone got any ideas? Quote Link to comment Share on other sites More sharing options...
Chrissb6 Posted February 23, 2015 Share Posted February 23, 2015 Hi is it fed from a wall socket? If so, see if there's a supply there first by plugging in another appliance or check it with a test lamp. If there is you can then move on to the hood in question. I've known kitchen fitters pick up a supply from anywhere, there could be another fuse spur hidden in the cupboards which might have a blown fuse supplying the socket supplying the hood. Seldom both the lights and fan fail together Quote Link to comment Share on other sites More sharing options...
Tango Posted February 23, 2015 Share Posted February 23, 2015 Plug something else in to check the socket is still live........or, if it's a fused spur, check that it's not tripped a breaker in the consumer unit...... Quote Link to comment Share on other sites More sharing options...
al_stu Posted February 23, 2015 Author Share Posted February 23, 2015 Yep the wall socket works fine with a lamp plugged in. It's a reasonably new build so although some cheap accessories the wiring is generally done to current building standards.checked the main fuse box and nothings tripped plus it's on same circuit as several other things. all the other things work in the kitchen, and the hood isn't on the main oven isolation switch thingymabobDamn it I might have to replace something else as well. It can go on the list for later in the year... Quote Link to comment Share on other sites More sharing options...

Anyone got any ideas?Can you post a photo of the front of the control unit the switches, not much can go wrong from what l can see Quote Link to comment Share on other sites More sharing options...
fredc Posted February 23, 2015 Share Posted February 23, 2015 the thing circled in red looks like thermal cut-outsome are one shot devices, once they blow they're doneedit: add 2nd pic Quote Link to comment Share on other sites More sharing options...
al_stu Posted February 23, 2015 Author Share Posted February 23, 2015 Thats just a wire you circled, in a clip - the photo makes it look more interesting.The thing you circled on the circuit is - I think - where the grey wire top centre of the photo leads. Which is around the fan unit then off to the plug.I'm wondering if there is one inside the fan (sealed unit as far as I can see) as I couldn't find anything else of note along the wiring.The front of the switches has been taken off with much swearing, but the brown/black connector at the bottom of the photo are the switches, the front is just a fascia to make them look pretty.Thoroughly puzzled, checked online but apart from a couple of people with the same question and no answer there doesnt seem to be much happening.

fredc Posted February 23, 2015 Share Posted February 23, 2015 follow the brown and grey wire and find what's attachedthen you've found the cut-out Quote Link to comment Share on other sites More sharing options...
al_stu Posted February 23, 2015 Author Share Posted February 23, 2015 Ok I'll try again tomorrow and see what I find, cheers Quote Link to comment Share on other sites More sharing options...
al_stu Posted February 24, 2015 Author Share Posted February 24, 2015 ok so the saga continues. The brown wire runs into the main fan.I'm not having much luck at getting into it although I think with the right encouragement (i.e. a smaller screwdriver) I can get these off which may reveal screws. The issue is that it looks totally unserviceable when I peer through the fan blades anyway... The other side looks like this and I have no idea how to get in Now what puzzles me (amongst other things...there are many, women, brakes, how some drivers make it from a to b without killing anyone...I digress) is if you look at the main switch, the grey wire here runs straight to the wall plug. So in my eyes there is nothing between the plug and the lamp. The fan (and orange wire) runs off a different section...so would damage along the orange wire also effect the light?

fredc Posted February 24, 2015 Share Posted February 24, 2015 I found a better diagram , its not a cutout its a microswitch http://www.buyspares.co.uk/images/mediator/3166/2%29%20wiring%20diagram%20%28flange%29.pdf Quote Link to comment Share on other sites More sharing options...
al_stu Posted February 24, 2015 Author Share Posted February 24, 2015 OKI have totally exhausted my DIY skills. I think I did that a while ago actuallyWhere the hell is the micro switch? Is it in the actual control panel? Or is that in main fan unit?I looked on the control panel and couldnt see anything. Quote Link to comment Share on other sites More sharing options...
eastanglianbiker Posted February 25, 2015 Share Posted February 25, 2015 with the amount of stress this is causing you it would of been far healthier and easier to go buy a new one Quote Link to comment Share on other sites More sharing options...
al_stu Posted February 25, 2015 Author Share Posted February 25, 2015 The thought had crossed my mind...as had the current resolution of put it back together and just don't use it hahaI just like to fix stuff rather than replace. Especially if I think it's a 2.99 part over a 100 pound replacement unit. Quote Link to comment Share on other sites More sharing options...
Joeman Posted February 25, 2015 Share Posted February 25, 2015 do you have a multimeter and do you know how to use it with mains voltage?should be pretty easy to trace the fault Quote Link to comment Share on other sites More sharing options...
al_stu Posted February 25, 2015 Author Share Posted February 25, 2015 Somewhere I do yesNo idea only used - rarely I might add - on cars.Might give it a google! Quote Link to comment Share on other sites More sharing options...
Grumpy Old Git Posted February 25, 2015 Share Posted February 25, 2015 It may be a combination of a duff switch and a duff fan.Disconnect all the feeds to the right/hand connector unit (looking at your last picture) and move the yellow and grey wires that feed the left hand stich (to the light) up onto the spare connections. Assuming the bulb is OK, then you should get the light working. If so - This switch is (partially) knafooed.The fans are usually sold as a sealed unit.But.... with a voltmeter (set to 240vac range) you should be able to find where the power gets to and take it from there.Good luck!
