Thermador wall ovens use PureConvection with a dedicated third heating element and fan, plus a precise RTD temperature sensor and control board that manage the whole baking cycle. When baking becomes inconsistent or the display shows a fault code like F2 (over-temperature) or F3/F4 (sensor open/shorted), it’s a specific component the control board has already identified — not a reason to assume the oven is failing wholesale.
We also see F7 (stuck touchpad key) and F9 (door latch/switch) faults regularly, especially on ovens that see heavy self-clean use. Our technicians carry the sensors and relay boards that fail most often on Thermador wall ovens for single-visit repairs.
