Thermador MBBS Microwave Oven Questions & Answers
Thermador Microwave Oven Model MBBS Serial No FD
Oh dear, I hope the magnetron still works. That plate you describe is called the Waveguide Cover. This cover must be kept clean otherwise the food particles will carbonize and cause exactly what you have described.
Contact the manufacturers web site for a supplier in your area or look on ebay, espares.co.uk depending on your location.
When it has been changed, I hope the magnetron/aerial is OK.
Thermador Built-In Microwave MBBS/01 Diminished Power
Smell could indicate burnt rectifier or mag. ( Or Both) Even a partially shorting transformer that hasnt yet fully shorted out and blown your fuse. I do not know that unit, but if it would happen to have 2 mag systems you could lose 1 and it still heat but probably only at around half power. It has been a long while since I have had to work on a Thermadore. But last time I did I rememeber most of their parts distributors I used to work with had all closed. Do you still have a manuel for that unit from when you purchased it?? Try to find a contact phone number to see if you can call thermador. Ask them if they have anyone in your area doing service for them. While it may no longer be under warranty, a servicer who represents them will have parts, or acces to parts and service literature that other servicers will not.
I need to buy a new MBBS Thermador Microwave
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!
Replacement or fix
just replaced our 6 year old Thermador MBBS ($750) with a GE JES2051SNSS
from Home Depot ($179). The bottom guide piece from the Thermador
bolted right on the bottom of the GE and positioned the new unit so the
front trim piece fit perfectly.

see the following steps , use the VOM and fix it. God bless you
- Check the power diodeThis
electronic component is responsible for transmitting current in one
direction. If the diode becomes defective it will cause your microwave
to not heat. Test the diode and replace it if necessary.
- High voltage capacitorResponsible
for storing electricity, this part is a key component in any microwave.
Remove, discharge, and test the capacitor to determine if it requires
replacement.
- Damaged magnetronResponsible
for generating waves and producing heat. When your microwave is no
longer heating properly, replacement will be required.
- Thermal CutoffsExamine
the thermal cutoffs on both the magnetron and the oven itself. Take off
one of the leads and using a volt-ohm meter on RX1, check the terminals.
If you get a result other than zero, replace the thermal cutoffs.
