I worked for an electrical company for a short while and allcof the dryers we booked in had the same problem... Burnt wires... Must be that the heat, heats them up faster and the electrical current also adds it's own heat..
What I don't get is that no company has ever tried solving the problem on their side.... A bit of heat insulation can go along way!

RE: I was finally able to solve the failure of the dryer, they were some melted cables. / Por fin pude resolver la falla de la secadora, eran unos cables fundidos.
