beko de2542 burning smell and pop?

Unusually running to hottest programme, a burning smell then a pop from the control panel. Switched off, cycle seemed to have completed. Weirdly there is still power to the panel and it will limp through a cycle although not properly. Won't use as surely unsafe, but if it was fuse then why is it still sort of working? Is there a thermostat that could have caused a trip for safety? Thankyou
