Same things for me. Thermador ought to be held responsible for this because it is a flaw for all of these ovens.

Hi, i found out from Thermador customer service that error code F64 means that the lower fan switch (located inside the bottom trim on the right side) is not being detected as closed. In my case, this was because the header (P4) on the Display panel had broken loose from the PC board and was no longer making contact. P4 is where the lower fan switch wires connect to the control boards (actually the display panel).

Make sure you hit the reset switch first... on top of the lower over... behind the panel...they trip easy and "kill" the oven.

Your t-stat or control board could be out on this unit. Can you check your t-stat and see if it's working alright? If it is, it's probably your board. Hope this helps~!

The control switch may be bad on it. If there are 2 elements on the top, they both are not bad at the same time.Check to see if the wires have not burned off the control switch first. Check to see if your breakers are O.K. Turn them both(maybe 3) off and then reset.

I found the lower circuit breaker had been tripped. That didn't fix the problem but upon further inspection whoever had worked on the unit years ago had dropped a screwdriver that had lodged between the oven wall and the rear casing and shorted out the lower heating element. I removed the screwdriver and oven works fine now. I don't think that will solve the cmmclow problem but maybee the curcuit breaker is tripped.
