Well, I finally did it. I cooked my ovens to death. It happened last week. The repairman showed up yesterday and told me it was time to put them out of their misery. I jumped in the car and ran to the appliance store to buy new ones.
They will be installed on Monday and hopefully I will be back up and running. I am in bread making withdrawal. I've promised myself to read the entire instructions manual and to keep it as clean as possible this time. I am bad about reading manuals. I chose to buy another Thermador as the old one worked really well until this last year. I got 12 years out of it. This one has a real clock and knobs and no touch pad which is what did the old ones in. Out with the old, in with the new. The shelter might be happier than I am about the new ovens!
