I was asked to look at a job late yesterday where double oven has stopped working so called out an oven engineer to look at it and he said nothing wrong with oven there is no power from cooker switch. I had a look and there is power leaving c/u but not arriving at switch. Customer did complain of an electrical burning smell coming from oven but I could neither see or smell evidence of this. Cannot see how the cable is routed he said it was done when kitchen extension was built 20 years ago, having taken plinths off units can see all manner of dodgy wiring so my concern is that thre maybe an inaccessible high resistance joint in the cable that has burnt. But then why would it take this long to manifest itself? Any other theories?
