Question about Thermador SMW272 Electric Double Oven
As for the display problem, you'll have to replace the Oven relay board and the display head.
As to the won't heat problem, mine is doing the same thing. On mine the Air Switch has malfunctioned. I hear a steady claking sound as the Stalled Fan relay cycles on and off. When it is operating normally, it will send a steady 120V power to the stalled fan relay. When it malunctions, the 120V signal is eratic and will totally shut off after the oven reaches the mid to upper 200 degree area. Once the oven cools off, you can restart it but the same problem will reoccur.
Replace the Air Switch and maybe the Stalled Fan Relay since it has been getting over used due to the constant on and off cycles it has been going through.
Hope this helps
