Bosch Range Error Code F2

The F2 code on a Bosch range means the oven temperature sensor is producing a resistance reading outside the acceptable range during a test or while the oven is in use. The control board monitors the sensor continuously to regulate oven temperature, and this code appears when the sensor signal falls outside expected parameters. The fault typically points to a defective sensor, damaged wiring, or a loose connection.

It is not recommended to use the oven while the F2 code is active. Because the sensor is not reading correctly, the control board cannot accurately regulate oven temperature, which could result in significant overheating or insufficient heat. The cooktop burners may still function normally, but the oven should not be used until the fault is resolved.

Resetting the range by cutting power at the breaker for a few minutes may temporarily clear the F2 code, but the error will return if the underlying problem is not fixed. A reset does not repair a failed sensor or damaged wiring. Persistent or recurring F2 codes require proper diagnosis and component repair or replacement to resolve the fault permanently.

A knowledgeable DIYer can often diagnose and repair an F2 error by testing the oven sensor with a multimeter and replacing it if the resistance reading is out of spec. Checking and reseating wiring connections is also a straightforward task. However, if the control board is at fault, replacement is more involved and some technicians prefer to have a professional handle that repair.

If the repair requires only a new oven temperature sensor, parts typically cost in the range of $20 to $60 depending on the specific model. Professional labor to diagnose and replace the sensor generally adds $100 to $200 or more. If the control board needs replacement, the total repair cost can range from $200 to $500 or higher depending on parts and labor rates in your area.
