Product review (4 stars): Amended Review
We purchased Thermador appliances for our remodeled kitchen to the tune of about $18,000.  It is unquestionably one of our worst ever customer service experiences.  The refrigerator came with rust on the handles.  Thermador referred the problem to a locally owned service company to replace the defective handles.  The technician scratched the panels necessitating service calls 2 and 3.  Shortly after the panels were replaced, the ice maker stopped working.  Three additional service visits and we still don't have ice.  In the just over two months that we've owned the appliances, we've had six service calls for the refrigerator, each requiring that we dedicate 3 hours or so. At this point, I don't know if we'll ever get ice.  Numerous phone calls to Thermador's customer service department reveal appalling customer service for supposedly high end products.  If given the chance for a do-over, we would undoubtedly choose products from a different manufacturer.

AMENDED REVIEW

Thermador decided to replace our refrigerator.  During the replacement process, it became apparent that the problem was due to incorrect installation of the product.  The installation was so bad that even after discovering the problem with the ice maker installation, the fridge still required replacement because the feet were damaged beyond repair during the initial installation.  I gave Thermador 1 star in my initial review.  I've raised that to four because they did eventually come through.  The only reason that it's not five is that their customer service department is difficult and unwieldy.  They could improve things a great deal by assigning your case to one person and allowing that individual to oversea the entire process.  Overall, we're now very pleased with Thermador.  The large national retailer that sold and installed our appliances is a different matter entirely.
