Thermador Range Error Code F141

F141 indicates that the slave microcontroller is not functioning. Thermador ranges use two control boards that communicate with each other, and F141 means the secondary processor on the Display Board is not responding. The fault is typically traced to a wiring or connector issue at connector P1B, a failed Power Board, or a failed Display Board.

It is generally not recommended to continue using the range while an F141 fault is active. A non-functioning slave microcontroller means part of the range's control system is compromised, which can affect normal operation and safety monitoring. Discontinue use and address the fault before operating the appliance again.

A power cycle or reset may temporarily clear the F141 code, but if the underlying cause is a hardware fault such as a failed board or damaged connector, the error will return. A reset is not a fix for F141 and should only be used as a step to confirm whether the fault is intermittent or persistent. Persistent return of F141 after a reset means the root cause must be diagnosed and repaired.

A knowledgeable DIYer can start by inspecting connector P1B and its wiring for obvious damage, corrosion, or loose seating, as this is the first recommended diagnostic step. However, if the wiring checks out, the repair requires replacing the Power Board or Display Board, which involves working with mains voltage components and should be handled carefully. If you are not comfortable working inside the appliance, a qualified appliance technician is the safer choice.

Repair costs vary depending on which component is at fault. If the issue is a loose connector or wiring repair, labor costs alone may apply, typically in the range of $100 to $200 for a service call. If the Power Board or Display Board needs replacement, parts costs can add $150 to $400 or more depending on the specific model, plus labor.
