I need to buy a new MBBS Thermador Microwave

I replaced the defective Thermador MBBS microwave with the Kenmore Elite model 721.66463500. This Kenmore microwave's cabinet has the exact physical dimentions as the Thermador. The controls are also very similar to the Thermador that it replaced. I suspect it was manufactured by the same company that built the Thermador.

Since it was an exact replacement, it fairly easy to adapt the old ducting to the new unit.

I spent the better part of three days trying to find a microwave that will fit and it's hard because so many are on line only. Last night I successfully installed the 2.2 cu. ft. GE profile counter top unit with inverter technology. The unit is an exact match, the Thermador even fits in the GE box with the styrofoam! I installed the venting materials for the side and rear vents and the platform at the bottom. I put the clips and decorative molding on and it's perfect! I found it in stock at Lowe's for $198. I took me about 45 minutes total to install. If I can do it, anyone can - 48 year old mom with 5 kids!

I would contact Thermador customer service ans ask if they have "drop-in" replacement or something close.

Thermador customer service is online here or you can call them at 1-800-735-4328.

amana and frigidaire appear to make microwave the same size as the MBBS.

While the size of the new thermodor microwave MBES is a minor difference from the old one, the new required trim kit is 2" taller. I will bring my thermodor trim kit to the appliance store and try and find a replacement. the Amana AMC2206BAS $299 appears like it may fit. Mine is under the counter, so I am less concerned about the appearance. I now realize buying a $700 microwave and a $250 trim kit was a total waste of money. Microwaves are disposable ****.

there is a replacement thermador that will fit but you will have to buy a new trim kit to receive the new microwave one year ago my microwave started sparking inside i called a repair man from percys in worcester a thermador qualafied tech he told us we needed a new microwave as ours was unrepairable i ordered a new one 800 dollars special order waited 3 weeks for delivery and then attempted install the unit fit in the hole but trim wouldnt go i was told i had to but trim kit 400 dollars i was pissed i returned the microwave and started asking questions one tech i talked to said clean your wave guide shield i did and the micro works. until today now it is humming and wont heat food. why when i took the micro apart were the internal parts labeled LG i thought i was buying a quality brand. good luck
