Whirlpool Washer Error Code F41

F41 indicates that the motor rotor position sensor (RPS) thermistor has been detected as open or shorted. The thermistor is a temperature-monitoring component built into the motor sensor assembly. This code is stored in the washer's fault memory and only appears when reviewing saved fault codes, meaning it was triggered during a previous cycle.

Since F41 is a stored fault rather than an active error, the washer may still operate, but continuing to run it without addressing the fault is not advisable. The RPS thermistor is a motor protection component, and a non-functioning thermistor means the motor has no thermal protection. Running the washer in this condition could risk motor damage from overheating.

Repair costs vary depending on what component has failed. A replacement RPS sensor typically ranges from around $20 to $60 for the part alone. A control board replacement, if needed, can run from $100 to $300 or more for the part. Adding professional labor, total repair costs generally fall somewhere between $100 and $400 depending on the fault and your location.

Some causes of F41, such as a loose connector or visible wire damage, can be addressed by a confident DIYer with basic electrical knowledge. However, properly diagnosing the fault requires following the specific resistance-check procedure in TEST #3, which involves using a multimeter to test the thermistor and wiring. If the RPS sensor or control board needs replacement, a technician with appliance repair experience is recommended.

Resetting the washer may clear the stored fault code from memory, but it will not fix the underlying problem. If the thermistor or wiring fault still exists, the code will return once the control board detects the abnormal reading again. The fault should be properly diagnosed and repaired, not just cleared.
