AJB73816004 Genuine Stator Assembly Including Rotor Position Sensor for LG Direct Drive Washing Machines

AJB73816004 is a genuine LG stator assembly for direct drive washing machines, and it comes with the rotor position sensor (RPS) already included. The stator is the fixed half of the motor, bolted to the outer tub, with the rotor turning around it. LG used several stator numbers across its washer range and no models are on file for this one, so match AJB73816004 against your old stator or LG parts list.

LG washer motor faults linked to the stator

In a direct drive washer the control board feeds current to the stator windings in sequence, and the rotor magnets follow, turning the drum without a belt. The rotor position sensor tells the board where the rotor is so each winding is switched at the right moment. A failed winding, a damaged sensor or a broken stator tooth can make the drum jerk, hum without turning, spin slowly, or stop with a motor or locked rotor error. Burnt windings and loose stator bolts also produce grinding and knocking. Test the windings and sensor before replacing the stator.

Part details

• Genuine LG part AJB73816004
• Stator assembly for direct drive washing machines
• Rotor position sensor (RPS) included
• Model fit not on file, match the number on your old stator

Replacing the stator on an LG washer

Unplug the machine and turn off the taps. Remove the rear or bottom cover to reach the motor, then undo the centre bolt and pull the rotor off its shaft. Unplug the stator and sensor connectors before releasing the stator bolts. Fit the new stator with every bolt tightened evenly, refit the rotor and centre bolt, and run a spin test with a small load.

Questions about this part

Do I need to buy the rotor position sensor separately?

No. This stator assembly is listed with the RPS included. If your old stator came without a sensor or uses a different connector, check the part number on it before ordering AJB73816004, as LG stators vary between models.
