reassembling thermador Thermatronic II lower oven door cmt21 Is there a mechanical schematic for thermador Thermatronic II oven model cmt21 lower door? Manufactured 1979. I took it apart because of cracked interior glass window. I can't find where to get a replacement glass. Now I don't know where two of the door parts go. They are two mirror-image aluminum thin plates about 9 3/4 inches by about 3 3/4. They are sort-of L shaped. Four of the six edges are bent parallel to the edge and to 90 degrees, The bent parts extend 1/4 inch perpendicular to the main flat surfaces. One edge (6 inches long) has a screw hole in it. I have trouble finding a place for them where they do not overlap the window. I thought they might have something to do with the shutter but I don't recognize any fit. I remember detaching them, one on each side when I took the inside apart. Everything else seems to fit other than these two pieces. I could also use info about getting replacement glass or replacement door.

I did remove the oven from the wall just before this started to happen (in ordeer to repaor an bad heating element. all the paels are back in place. What is goig on? Where is the exhausts air coming from if not from the oven?

I have a 1983 Thermatronic II model CMT21. It was vented to the exterior through an old clay vent line that had originally been used to vent a gas range through the roof. My roofers removed the clay pipe from the roof and covered up the opening under the belief that the pipe was no longer needed. Does the CMT21 have to be vented? If yes, can I vent it to the kitchen instead of the exterior? Thanks.
I own a Thermadore CMT21 and the microwave side just quit. I'm looking for a schematic for the oven. Does anyone know where I could locate it. Also when the Microwave died it made a loud pop. Any suggestions on what failed in the unit and if parts are available. I also have a New Cross Flow Magnetron tube kit Buttetin CMT-177 for Thermadore which I plan to install at the same time. This came out as a replacement for the discontinued Mag tube in my oven. Thanks, Dean
