Tap the display and set the cooking program once more. If it comes back, it needs a visit. ### What should I try first when my Thermador says Humidity Sensor Error? Touch the display and set the cooking program again, which is the only home step in the manual. A second appearance means the oven needs a visit. ### Is Humidity Sensor Error on my Thermador the same as Temperature Sensor Error? No. They are separate messages that name different sensors, even though the manual gives the same first step for both. Tell the technician exactly which wording appeared. --- **[Read on the site: Thermador speed oven showing Humidity Sensor Error](https://ovenrepair.center/error-codes/thermador-humidity-sensor-error/)** **[Book a visit with OvenRepair.center](https://ovenrepair.center/schedule/)**
