Customer Questions and Answers for Rotor Position Sensor by Whirlpool

Hello Ash, the fault code refers to the main control board not detecting a signal from the motor's Rotor Position Sensor, this can occur if the motor is not turning, the sensor is faulty or there is a problem with the wiring to the motor or sensor. For any further help please include the model number.

Aso, You will want to check the hub of the washer as the OL indicates an overload. This means that too much was clothing was put into the unit or that the hub is not releasing to allow the unit to operate properly.

Brandon, That code flashes when the control detects or thinks there is an unbalanced load. So if it flashes with no clothes present it would be a faulty control. W10763749

Michael, the tub bearings and driveshaft will need to be inspected for corrosion. If there is corrosion on the driveshaft or sleeve, the bearing and tub seal kit W10435302 would need to be replaced using the installation tool kit W10447783.

Hello Jim, the rotor position sensor only signals the board for motor speed and direction of rotation. Feedback signals from the motor windings to the board, are interpreted by the board as a balanced/unbalanced load. If the code is showing every load that can be caused by a clothes basket that can no longer center itself or worn spin bearings. You can pull out the basket and check if the center opening that goes over the shaft is worn, if not then its the spin bearings may be binding/dragging.

Cal, Tilt the unit back and access the rotor and stator, check to make sure that there is nothing impeding them and that the RPS sensor is in the correct position and not loose. If this checks ok but the tub will not spin freely then it sounds as though the bearings on the unit have seized up. The bearing part number will be W10435302.

Pro, if the model number for your appliance could be provided in a new inquiry, this will allow for the most accurate information to be presented. However, as a general test, you may want to test each wire on the wiring harness from end to end for continuity. From the information provided, it sounds like there may be a wire issue.

G Thomas, SD is a suds detection, this may signify a load is bunched or twisted around the agitator, there is excessive detergent that was used, even a problem with the basket not turning freely due to friction on the drive mechanism, and not allowing the basket to engage.

Jason, If the tub will spin in the diagnostic mode but will not in the normal cycle then this would be a faulty control board.

Jerry, you will want to check the rps and stator yes. You will also want to check the bearing assembly as you have what is known as a floating basket. Over time, the basket will catch on the drive shaft not allowing it to seat down properly when the water is draining. If the basket is catching on the shaft, it will cause the UL error to occur. If the basket is catching, you will want to use the bearing kit part number [W10435302] along with the tool kit [W10447783].
