Thermador MC30WS (Masterpiece Speed Oven)
Owners usually install the MC30WS in a wall stack, where it does the job of a microwave and a second oven at once. It belongs to the Masterpiece tier and runs on a busier control board than a plain microwave, with two heating systems sharing one cavity and one set of touch controls.
That arrangement helps us. The microwave and the convection systems are largely independent, so a unit that browns food but will not microwave, or the reverse, tells us which half to examine before we open anything. If neither heats while the display and fan carry on, we widen the search to the shared control side.
Touch pads deserve their own note. Thermador documents an E11 condition on its microwaves where the keypad stops responding, often after condensation, and the same applies here. Wiping the pad dry and cycling power is worth a try before anyone talks about replacing a keypad.
It tells us the microwave side is working and the convection side is not. Because the two systems are largely independent, we go straight to the convection element and fan instead of the control board.
Yes. Thermador documents an E11 keypad condition often tied to condensation. Dry the panel, switch the power off at the breaker for a minute, and try again before assuming a new keypad is needed.
The exact code and what the oven was doing when it showed. That detail speeds up diagnosis, and it lets us tell whether the code points to the keypad, a heating function or the board.
