dear peter,ours has done exactly the same thing,we suspect the element.ours is a hotpoint double oven.have you got a top one to be going on with? meanwhile,we would also welcome any advice on what is wrong with the blessed thing!
sprayed foam insulation has,apparently been applied (about 10 years ago) to the underside of the roof tiles on the house we are about to buy. we have been told this can cause damp in the roof timbers and wonder the best way to get some ventilation up there,short of re-roofing.
