I installed a new electrolux electric hob today,and after switching it on to let the plates burn off a bit,I was surprised after about 5 minutes when there was loads more coming from underneath the hob,no nasty electrical burning smells or nothing just the same smell and smoke you get from the plates.
but after 10 minutes it was still smoking like a pipe,but after speaking to my supplier his fitters tell me all of these ones do that for about 20-30 minutes when they install them then they are fine.
I left it for a bit and sure enough seems to have done the trick,so keep in mind if you fit a new electrolux hob,to add an extra half hour to the job while you set the smoke alarms off!!LOL
