I have a Thermador oven that after a power outage now blinks the dreaded "22" code on the LEDs
which presumably means the micro-controller on the the control board has a problem accessing the
EEPROM. The problem appears to be with the 00676192 control board and I took it out and checked
it out but there is not visible damage with it.  I wanted to send it to a repair house to get it fixed as a new
one is close to $500 but so far I have not been able to find a place to accept this board for repair.  Although
they haven't told me why they won't accept it, I presume it is the micro-controller part (M30620FACFG)
is bad and hard to find a replacement for it. Not only that I think just replacing the IC may not be sufficient
as you also need to upload some code into it.  Without the knowledge of how to do that it may be impossible
to repair.  My next option is to buy a replacement for ~$500 but I am finding out that there are two versions
of this board even though they are both under the same 00676192 part# and they have different amount of
fast-on terminals on each. If I buy the newer (cheaper) board does anyone know how to connect all the wire
connections from the older board with this newer one ?
I am attaching a couple of pictures to show the connectors and fast-on terminal differences between my existing
board and the one I am trying to get for ~$400.

Thanks in advance,
Wah

Sorry, looks like the pictures never got attached.  Thermador_new.jpg is the new board and thermador1.jpg is my existing control board.

Is your appliance a US made model? I am having trouble finding the model number given.

Yes it is an US model with four burners. Bought it right here in the Boston, MA area.  I have attached here the user manual.

We need the model number directly off the appliance itself. It will be on the appliance data tag.

Good afternoon,

Thank you for the model number. i was able to find the part number 00676192 to be the correct replacement. However, i am not able to find how to install this part into your model. or how the connectors will need to be replaced.
