I have a old Thermador MCM255 - combo microwave/convection and double oven below.
Recently, my microwave doesn't work, now my convection oven does not work.
I changed out the fuse in the back but still doesn't work. Any suggestions?
Is it worth repairing an 23 year wall oven?
Thanks

Unfortunately the convection heating and air distributing parts, as well as most microwave parts for your oven are no longer available.

Gene, we are replacing the Thermador MCM 255 in my house. Do you have the overall dimensions. We are trying to buy a new unit and we need to know both the inside and outside dimensions. Thanks for any help you can provide. Marc Shaw.

Hi Marc,

I could not find the dimensions of such old oven.

You can measure the out side dimensions, then pull it out for a few inches and measure the cabinet opening.

I'm afraid some cabinet alterations should be necessary.

Best regards.
Gene.

I was able to find a new microwave emitter and the microwave oven works great. My problem now is the plastic shelf guides are burning due to their age and I can keep them going for a little while longer by filing down the rough edges that catch the microwaves. That stops the smell. Also you have to keep the wire shelf away from the back so it doesn't arc. Some thermador service men are good at keeping this going. The shelf guides are discontinued by Bosch because it's a bad design to have a convection oven and a microwave in the same unit. You won't find those in modern replacements and I'm sure I'm not the first person to report these problems. I'm looking to replace the whole oven which measures 24-1/2 x 47-1/2 including the lower oven which is fine. But there are no microwave uppers and conventional lowers available in that width. Only 27" and 30" and that runs into cabinet repair. Would love to find the rack slide kit L & R. but all inventory among the obsolete parts people is gone. Good luck.

Any ideas on why the microwave & the convection do not heat & all other functions on the combo work, panel fans thermostat etc. This happened after a fuse was replaced the 20A 250V. Before everything worked well. Yea the door switches are ok. Thanks
