Sorry for my late reply but I have had no computer for a few weeks. The developments since my last post are as follows. The oven suppressor https://www.ebay.co.uk/itm/SAMSUNG-...ssor-Filter-for-Oven-Cooker-PCB-/382242309533 is fitted to several different ovens (Samsung & Lamona ) & the problem is that the neutral connection of the coil on the pcb pokes through a hole in the thin plastic mounting & either permanently or temporarily shorts to the oven casing. Trading standards agreed with me that it was a potentially dangerous design, particularly if protective devices failed & they would take up the case with Samsung. I await their replies.
