Thanks for the reply. Do you mean the thermometer switch needs replacing? If that's the case then do you know why the new thermal cut-out failed to cut the oven when the temps got way too high? Also could it be possible I may have switched the cut-out wires while installing the new thermal cut-out?, as the replacement does look cosmetically different from the original so I couldn't go by the original for reference (the blue dot).
