Kenmore Washer Error Code F41

F41 on a Kenmore washer means the control board has detected an open or shorted circuit in the thermistor portion of the motor rotor position sensor (RPS). This thermistor monitors the drive motor's temperature to protect it from overheating. The code is stored in the washer's fault memory and is only visible when you manually enter the saved fault code viewing mode. It signals that the motor sensor circuit or its wiring needs diagnostic testing.

Because F41 is a saved fault code and not an active stopping fault, the washer may continue to run cycles, but operating it without a functioning motor thermistor means there is no thermal protection monitoring the drive motor. Continued use without repair could risk motor overheating if the underlying fault is causing actual temperature monitoring failure. It is best to diagnose and resolve the fault before running additional loads.

Resetting the washer may temporarily clear the stored F41 fault code from the display, but the code will return if the underlying problem in the RPS thermistor circuit has not been repaired. Because F41 is a saved fault that only shows during fault code review mode, clearing it without fixing the root cause means the problem will continue undetected until the code is checked again. Proper diagnosis using TEST #3 is necessary to resolve the fault permanently.

A knowledgeable DIYer can begin by inspecting the wiring harness and connectors between the motor RPS sensor and the control board for visible damage, loose connections, or corrosion. If the wiring looks intact, further diagnosis following TEST #3 requires a multimeter to measure thermistor resistance at the RPS connector. Replacing the RPS sensor is a mechanical repair many experienced DIYers can handle, but if the control board is at fault, that repair is more complex.

Repair costs depend on what component has failed. A replacement RPS sensor typically costs in the range of $20 to $60 for the part alone. If the wiring harness needs replacement, parts and labor together could range from $80 to $200 depending on the service provider. A machine control board replacement is the most expensive scenario, with parts and labor potentially ranging from $150 to $350 or more.
