Sterling GCT (Glass Cook-Top)
This isn't really an answer; only empathetic communication. I too have this brand with the same problem. It's original 1991 booklet names the appliance model numbers as either GCT 360, 361 or 362. And the address for them was New World Domestic Appliances LTD, New World House, Thelwall Lane, Warrington WA41NL Cheshire, U.K.
