So I searched and searched for a tear down for the Thermador and found nothing. I did come up with a thread on the Samba that included drilling and brazing and all kinds of sillyness. So I dug in; here you go. The great mysterys of the thermador revealed. Basically the rear cap snaps off ( tap it off with a screwdriver, don't pry it off ), once you get the cap off you need to unscrew the three stainless screws that are covered in tar. Get yourself a knife and heat that bad boy up and use it to cut the tar seal. Cap pops off, cage comes out. Pretty easy. No drilling, no cutting, or welding. Rebuild as needed.
