Yesterday I decided to self-clean my oven. 4 hours into the 4-1/2 hour cycle it started buzzing and an error code displayed that it was overheating - it stopped the process - cooled down - then died - totally fried the motherboard and blew the oven fuse -costing $700 to fix and am being told to never again use the self-clean /// the repair company said they've had 1000's of ovens fail thus way AND the appliance companies do nothing about it. Research shows it's been reported as happening since 2010!!!' Why do they keep making them this way????
