Bosch Range Error Code F141

F141 means the main control board's master microcontroller has detected that the slave microcontroller is not functioning. Bosch ranges use two processors that work together, and this code fires when the primary processor cannot confirm the secondary one is running correctly. The range will typically shut down or refuse to operate until the fault is resolved.

Start by cutting power to the range at the breaker for 5 minutes and restoring it to see if the fault clears, which rules out a temporary initialization failure. If F141 returns immediately, the most likely fix is replacing the main control board, since the slave micro is integrated onto that board and cannot be replaced separately. Verify your incoming line voltage is correct before condemning the board, as low or unstable power can cause this fault without board failure.

Yes, a power surge is a well-documented trigger for F141. Voltage spikes can damage the slave microcontroller chip or the communication circuitry on the control board, causing the fault to appear immediately after a storm or power grid event. If F141 appeared right after a surge, inspect the control board for visible burn marks or damaged components. In most surge-related cases, the control board will need to be replaced.

No, operating the range with F141 active is not advisable. The slave microcontroller often handles safety-critical functions including temperature monitoring and burner control. With this processor in an unknown state, the range cannot guarantee safe operation, which is exactly why Bosch designed it to shut down when this fault is detected. Do not attempt to bypass the error and use the appliance.

If a control board replacement is required, the board itself typically costs between $150 and $400 depending on the specific Bosch model, with labor adding $100 to $200 for a qualified technician. Total repair cost commonly runs $250 to $600. If the fault is caused by a power supply or wiring issue rather than a failed board, costs can be lower. Get the board part number from your model's wiring diagram before purchasing to ensure compatibility.
