Creda Aspire double oven. 20 yrs old in use until a month ago, no faults ever. Rubber seal on oven could do with replacing as it allows moisture to escape. Cracks across ceramic plate happened when I removed an old adjacent worktop and it flexed the oven. Used it for a year after that with no problems, I did find the replacement on eBay for £50 so I guess you'd be able to do the same.
