hi.i have a belling electric cooker.about 9 months ago i had the main oven element replaced.the element had blown but the fan+oven display still worked.on xmas eve we were cooking when there was an almighty bang+flash of light coming from the oven door.i turned off the power+checked the element,it had blown again.this time the display+fan were not working as well.the cooker also as a grill/oven and ceramic hob.these are still working.is there a separate fuse in the cooker for the main oven that could of blown when the element blew????.the cooker is free standing.
