pull the appliance out.remove the front top panel.look inside behind the control panel for a torpedo shaped blue bit with 4 wires coming from it somewhere hanging in the wiring loom.2 blue and 2 white coming from 1 end of it.if this bit has a brown burn mark in the middle of it it needs replacing to stop the cooker cutting out.about £30 and very easy to fit
