I have had a Thermador oven since 1998. The convection element went out months ago. I had been using the bake mode. Recently, the bake element also went kaput. I am just a housewife trying to keep things cheap so I figured out how to fix it. AppliancePartsPros.com made it easy to find my parts. And it came in less than 2 days!!!!! My husband and I replaced both elements in less than an hour and everything works great! Highly recommend this company for parts. They also have videos on YouTube showing you how to replace the parts. For someone who has no business trying to repair appliances, we did pretty well.
