The Rotor Position Sensor is an OEM part for LG washing machines. This sensor monitors the speed and direction that the washing machine tub is spinning. It ensures the tub rotates properly in both clockwise and counterclockwise motions during cycles.

Causes of a bad rotor position sensor can include wear and tear from extended use agitating heavy loads, breakage from impact or moisture damage, or compromised wiring over time.

Symptoms of a bad rotor position sensor include:

  • Tub failing to spin or agitate clothes during cycles
  • Inability to detect spin cycle direction changes
  • Repeated errors messages related to tub operation
  • Long cycle times as the sensor cannot monitor load movement

This OEM LG part is also compatible with some Kenmore models.

Questions & Answers

For Lg Rotor Position Sensor (Part Number: OEM17920215)

1 Answer

Tommy, The UE error is an off balance load and you will want to make sure that when you reinstalled the tub that the shocks are in place properly and check to make sure that the springs are in place properly. If this checks ok and the motor and stator are good then this would likely be an issue with either the wiring or the control board.

Ashley, We wouldn't expect you to need the control board, but first check the basics, washer properly levelled, loaded properly, using the proper type and amount of detergent, (no sudsing), and the washer drains properly(check the drain hose for kinks and twists. If all's OK then replace the rotor position switch, and check to make sure the wiring connections are clean, tight and proper.

Mitchell for Model Number WM2016CW

My washer spins well going clockwise (as seen from the back of the machine looking at the rotor), with a faint clicking sound, but spinning counter-clockwise, it grinds and shakes violently. I haven't gotten an LE error code. The rotor is not the problem. I even took the tub apart and the bearings appear fine, too (no corrosion or any indication of typical rotor problems). You advise checking the resistance of the sensor, but I'm not sure how to do that or what tool is required. Is there a helpful video or article I can watch?

1 Answer

Hello Mitchell, You will need an ohm meter to read the resistance of the motor from terminal 1 to terminal 2, terminal 2 to terminal 3, and from terminal 3 to terminal 1. You should read about 5 O to 15 O of resistance. To test the Hall Sensor, If measuring voltage from the Main PCB Assembly to the Hall Sensor, use the following steps: 1. Unplug power cord. 2. Remove rear washer panel. 3. Locate Hall sensor connector on the stator behind the rotor. 4. Place meter leads on terminals 5 to 4, white to gray. 5. Plug in power cord, close door, and press power button. DO NOT PRESS START! 6. You should measure 10 to 15 Vdc. If 10 to 15 Vdc is present, control board, white wire, and gray wire are OK! If not follow testing output voltages on control board. 7. To measure output signal voltage from the hall sensor, carefully move test leads to terminals 1 to 4, blue and gray. Slowly rotate motor rotor by hand. You should read a pulsing 10 Vdc. If 10 Vdc is measured from 1 to 4, move lead on blue wire to red wire, terminal 2. Repeat rotating motor rotor by hand. You should read a pulsing 10 Vdc from red to gray. 8. If pulsing 10 Vdc is measured from 1 to 4 and 2 to 4, hall sensor is OK! If either test netted only 9 to 10 Vdc without changing (no pulsing) the hall sensor is likely defective. Disconnect power by unplugging washer and ohm check hall sensor to verify failure of the hall sensor.

Hello Bob. You will need to check the pressure hose and make sure it is still attached and is not damaged.

Paul for Model Number LG WM1814CW Washing Machine

Hi, Our washer fills with water but doesn't tumble properly and stops with an "LE" error code. The drum "judders" and will sometimes turn with a scraping noise from the back. However, with power off turning the drum has no such noise and it moves fine. In test mode, the first three motor tests (tumble clockwise, low speed spin and high speed spin) do nothing and the motor is frozen, drum not turning. In the tumble counterclockwise test, the drum spins with the scraping sound but the display of RPM shows 0. The motor is getting quite hot. Any typical causes for this type of issue? Thanks, Paul.

1 Answer

Paul, The LE error code is a motor locked error. You will want to do the following to determine what part is needed. • The connector (3-pin, male, white) in the MOTOR HARNESS is not connected to the connector (3-pin, female, white) of STATOR ASSEMBLY. • The electric contact between the connectors (3-pin, male, white) in the MOTOR HARNESS and 4-pin, female, white connector in the MAIN PWB ASSEMBLY is bad or unstable. • The MOTOR HARNESS between the STATOR ASSEMBLY and MAIN PWB ASSEMBLY is cut (open circuited). • The hall sensor is out of order/defective

Hello H.N., We can assist with a bit of help from you. First we will need a model number from the units' I.D. tag. Then we will need a description of the problem the unit is giving. Thank you for your understanding and patience in this matter.

Hello Manu. The "tE" error is triggered when the MAIN BOARD fails to receive signal input from the THERMISTOR. You will need to replace the thermistor.

Hello John. They should not travel more than 2 inches during a spin cycle. Also, they should have light resistance. Look for a loose motor also.
