🙁 I hope someone out there can help me locate a control button for my old reliable Thorn EMI Tricity Sovereign Cooker Model 4638 Serial No SIH 118600307. There are 2 rows of 4 small plastic buttons, a bit like very small golf tees, under the digital display screen, one of which I managed to snap off when cleaning the hob. These buttons control various functions on each of the ovens. I have broken the temperature control button for the top oven. I fear all spares for this model may now be unobtainable due to the age of the cooker – about 18 years old. Does anyone have one of these little gismos looking for a home or know where I could find one? Anyone? Please.
