Hi, I understand what you are saying and agreed it is reaching the end of its life but where in this heater, with resistive loading, is the extra draw of current coming from to cause this sudden problem?
That's what i'm saying ...who knows?? You have 25+ years of dust and debris to start with. Depending on what's happened to that failed heating element, you could even be picking up one portion of that element!!
On units of this size and of this age, you can be just scratching your head getting nowhere fast!! It sounds as if this unit is going to be uneconomical exercise to repair, which leaves replacement, or finding another source of heating energy to replace this unit. I personally wouldn't be wasting anymore time on it. Even if you find further problems with the elements, your not going to be able to fix them, without taking the unit and bricks apart!! It's a dead duck mate!! lol!!!
