Bosch Oven Error Code F141

F141 means the slave microcontroller in the oven's control system is not functioning. This secondary processor handles communication between the Power Board and the Display Board. The fault points to one of those two boards as the likely cause, or to the wiring and connectors between them. The oven will typically not operate normally until the issue is resolved.

A power reset, such as turning off the circuit breaker for a few minutes, may temporarily clear the code, but it will return if the underlying hardware fault is not corrected. If the slave microcontroller is not functioning due to a bad board or a wiring connection problem, the error will reappear once the oven powers back up and runs its self-diagnostic routine.

Repair costs depend on which component has failed. Wiring and connector repairs are generally inexpensive, often falling in the range of a standard diagnostic and labor fee. Replacing a Display Board or Power Board typically costs between $150 and $400 or more, including parts and labor, depending on the specific oven model and your location. Getting a diagnostic estimate before authorizing repairs is advisable.

The first diagnostic step, checking connector P1B and its wiring on the Display Board, is something a knowledgeable DIYer can attempt after disconnecting power to the oven. However, if the wiring checks out and a board replacement is needed, working inside the oven's control system carries electrical risk and requires correct part identification. Most homeowners are better served by a qualified appliance technician for board-level repairs.

No, you should not attempt to use the oven while F141 is active. The fault indicates a control system failure, which means the oven may not regulate temperature, respond to commands, or shut off properly. Continuing to operate it in this state could create a safety hazard.
