This gentlemen is a beaut… right hand side rings dont work, ohmic values the same as the left rings so has to be PCB? £190 later, reinstall hob switch on and …nothing. 🙁 turns upside down to see if volts are going to it, and they are glowing hot ????? turn it back the right way and it works for a wee while untill I tried the Duel circuit then nothing… this one has me stumped , it only works upside down for the right hand side. Magnetic pans anybody.
