Product review (1 stars): Parts Not Always Available
I own a thermador electric oven, and I have friends who do.  Thermador electronic displays are notorious for failing.  And Thermador does NOT sell replacement display parts!  They have you remove the electronics and mail them to a repair contractor in Illinois for $179.95.  There is NO guarantee that the display can be repaired.  If you doubt this you can  contact Thermador directly or google the subject and you will see for yourself.  Be careful!
