Product review (1 stars): Steer clear of Thermador, poor product, poor warranty, poor customer service
Stay away from Thermador ranges in general.  They have a bad warranty and don't stand by their product.  We purchased a home that was only 1.5 years old with the PRG486JDG range in it.  A few months later we notice issues with this $13k oven.  The rack guide on the oven broke at the weld due to poor welding.  Next we notice that some rows of the control panel are not lighting up.  Lastly the hood makes a horrible noise when the blower is on high.  They will not warranty anything since we are the 'second owners', even though the oven is in the same place that they installed it.  They want $100 to come to my house, $120 per hour to look at the issue and then the cost of parts on top of that.

THIS IS A $13,000 OVEN!!!!  IT SHOULD NOT BREAK WITHIN 2 YEARS!!!
