My tricity bendix cooker is 20yrs old and is a Sovreign IV. The large halogen ring at the front-the one that has been most used, is temperamental and seems to come on only after one or other of the rings has been on for a while. Once on its difficult to get it back off as the knob keeps twisting round. When it finally is off, its not usually in the normal off position! Is any repair going to be cost effective as its in near perfect condition apart from this. Did wonder if there was a huge amount of gunge stuck under the switch-maybe needs to be taken apart and cleaned?

It's just happened to our Tricity Strata cooker; the problem was also with the ring we use the most and I found that the copper contacts in the switch had degenerated and weren't 'breaking' as they should causing the fuse to trip. I think a new switch is needed; hope this helps.

could be it needs cleaning as the discs get stuck with grease over the years
