I have a Thermador cooktop (second one) and two Thermador ovens. had to replace my first Thermador cooktop because they changed the ignitor and of course the whole cooktop had to be replaced. Purchased new one for $3K a little over three years ago. The bolts that affix the burners to the cooktop are completely rusted and Thermador won't honor replacement. they will pay for parts but not labor (the most costly part) and one of the ignitors has to be replaced which cannot be replaced unless all of the burners are removed! ugh-very frustrated. will change brands when replacing
