Electrolux EOB945 oven; Light on front of appliance is on so power to unit, but no fan, grill, heat nor any noise. Last night after turning oven off i noticed a slight ticking noise for the first time, which i couldnt get rid of without turning off power to the appliance. Presumed this was to with clock/timer which never get used, but today no part of the appliance works, any ideas? Thanks for any help you can give!
