Bosch Oven Error Code E201

E201 on a Bosch oven means the control module has detected an open circuit in the temperature sensor for the second oven cavity. This tells the oven that it cannot get a valid temperature reading from that cavity. As a safety response, the oven shuts off heating in that cavity and runs the cooling fan at high speed until the fault is corrected.

You should not continue using the affected cavity while E201 is active, as the oven has disabled heating there precisely because it cannot monitor the temperature. Attempting to bypass this could pose a safety risk. The cooling fan running at high speed is also a sign the oven is in a fault state, and continued use could potentially worsen an underlying wiring or component issue.

Repair costs vary depending on the root cause. A replacement temperature sensor typically costs in the range of $20 to $80 for the part. If a professional technician is needed for diagnosis and labor, total repair costs can range from $100 to $300 or more. A control module replacement, if required, is the most expensive scenario and can push costs to $200 to $500 or higher depending on the specific model.

In many cases, yes. Start by unplugging the oven and inspecting all wiring connectors leading to the Cavity 2 temperature sensor. If a connector is loose, reseating it may resolve the fault. If the sensor itself fails a resistance test, replacing the sensor is a repair many experienced DIYers can perform. If the wiring and sensor both test correctly, the issue may be a faulty control module, which is more complex to replace and may warrant a professional technician.

A power reset, such as unplugging the oven for a few minutes and plugging it back in, may temporarily clear E201 if the fault was caused by a momentary signal disruption. However, if the underlying cause is a loose connection, a broken wire, or a failed sensor, the error will return. A reset alone is not a repair and should only be used as part of the diagnostic process.
