I have a competence B4100-1 under oven.the oven switches on ok and goes on and off with the thermostat,but after about 15-20 mins it cut out and every thing stops.then a while after it has cooled down you can turn it on again and the cycle of events starts again.Also there is no label with a serial number for model reference near the door or anywhere else on the oven,I suspect it has come off when being cleaned,which is making it difficult to reference the part, as I get asked for this number so that the supplier can identify the correct part .Can anyone help with advise on this problem

pull cooker out.remove the smaller top panel behind the control panel.look in there for a torpedo shaped blue thing with 2 white and 2 blue wire attached to it.it usually is cable tied in to the wiring loom.If there is a burn mark on it then this will be the problem.that part makes the cooling fan come on to stop the cooker cutting out.I think they are around £35 so not cheap!!
