Product review (1 stars): DO NOT BUY
I love the concept of this oven. It was the perfect answer to my small kitchen & my need for multiple ovens. We have had it a little over 2 years. We had two service calls while it was still under warranty for the warming drawer light (a small thing, but still, it should work). We are now on our 3rd service call for the microwave/convection that makes a horrible sound just before it shuts down completely & will not turn on again. Now out of the manufacturers warranty, we are using the extended warranty which sends repair folks who seem clueless about what to do. Takes them a week to come out & a few weeks for whatever part they think is wrong to arrive. The last time it  broke in the same way within 2 weeks of being repaired. Maybe time for someone to think about what is causing this part to break? Or maybe just replace the microwave? The extended warranty folks seem to be doing everything in their power to avoid that & Thermador has not returned my calls.
So for now, the microwave is broken more then it is fixed. Long periods of time with the microwave out not got good for my busy family.
I understand these now have a 2 yr manufacturers warranty. Unfortunately when we purchased it it had a 1 yr.
Great concept, poor quality & service. Over $5,000; it should actually work. Our last oven was a Jennair & was still working when we replaced it after 17 years.
