Re: NEFF H7871NOGB/03 Combination microwave oven reset code?

Thanks MicroGerry for information – helped in the final diagnosis! Fixed it by replacing lower display/control module (£196!), as suggested, and replacing all (yes, ALL) transistors on the Power Control Module – a couple of £ compared to £123 for replacement PCM. I conclude that, when the track vapourised, it momentarily put 240V on the 12V rail, which promptly took out the (normally indestructable) 12V regulator and all the transistors. For those who haven’t hit this problem yet I would recommend plastic sheet between the two pcbs – should stop this problem, if it occurs, from destroying that really expensive lower D&C module.
