Maytag Washer Error Code F41

F41 on a Maytag washer means the motor rotor position sensor (RPS) thermistor has been detected as open or shorted. The RPS thermistor monitors the motor's temperature as a protective measure, and an open or short condition means the control board cannot get a valid reading. This code is only visible when reviewing saved fault codes in the washer's diagnostic history. Diagnosis involves checking the thermistor's resistance, the wiring harness, and the motor control board.

The F41 code disables the thermistor's ability to monitor motor temperature, which removes a key protection against motor overheating. Continuing to run the washer without resolving this fault could allow the motor to overheat without the control system detecting it, potentially causing further damage. It is advisable to diagnose and repair the fault before resuming regular use.

Because F41 is a saved fault code rather than an active fault that halts the cycle in real time, a power reset may clear the displayed code temporarily. However, if the underlying problem with the RPS thermistor or its wiring still exists, the fault will be logged again the next time the condition is detected. Clearing the code without repairing the root cause does not fix the problem and may allow further damage to occur.

Some aspects of diagnosing F41 are accessible to knowledgeable DIYers, such as inspecting the wiring harness and connectors near the motor for visible damage, corrosion, or loose pins. However, properly testing the RPS thermistor requires a multimeter and comfort working near motor components. If the RPS assembly or motor control board needs replacement, the repair becomes more involved and may be best handled by a qualified technician.

Repair costs vary depending on what component has failed. A replacement RPS assembly typically ranges from around $30 to $80 for the part alone. If the motor control board requires replacement, parts costs are generally higher, often ranging from $100 to $250 or more. Adding professional labor will increase the total cost, typically by $80 to $150 per hour depending on your location.
