Lg Washer WT4870CW Will not agitate or doesn't agitate

The Motor Rotor Assembly is an OEM part for LG washing machines. This component is crucial for the washer's motor operation, as it works in conjunction with the stator to create the electromagnetic field that drives the drum. It ensures the drum rotates effectively during the wash and spin cycles, facilitating thorough cleaning and efficient water extraction.

Over time, the motor rotor assembly can wear out or become damaged due to regular use, exposure to water, or excessive loads. Causes of a bad motor rotor assembly include bearing failure, corrosion, physical damage, or electrical issues.

Symptoms of a bad motor rotor assembly include:

• The washer not spinning or agitating
• Unusual noises such as grinding or squealing during operation
• The drum not turning or rotating inconsistently
• Error codes related to motor issues

This OEM LG part is also compatible with Sears/Kenmore.

This washer motor stator assembly is the stationary windings of the direct-drive motor. Replacing a weak or shorted stator restores smooth drum tumbling and strong, consistent spin performance so wash cycles complete properly.

• Creates the rotating magnetic field that drives the rotor and spins the inner basket
• Works with the rotor to provide torque for wash/tumble and high-speed spin
• Common symptoms: drum won't spin or tumble, stops under load, or motor hums without turning
• Burnt odor or visible heat damage on windings can indicate stator failure

• Disconnect power and turn off water; access the motor from the rear panel
• Remove the rotor center bolt and slide off the rotor; strong magnets—handle carefully
• Unbolt and remove the stator; transfer/reconnect the motor position (Hall) sensor and harness if present
• Tighten fasteners evenly; verify drum rotates freely by hand before restoring power

The Lid Switch and Lock Assembly is an OEM component specifically designed for LG washing machines. It contains both the switch that detects when the lid is closed, as well as the metal lock mechanisms that securely engage the lid during active cycles. This switch contains a 47-inch wire harness with 6-pin plugs.

Symptoms of a bad lid switch and lock assembly include:

• The washer not starting or agitating with the lid open
• Inability to fully close or lock the washer lid
• Error codes related to sensed lid position issues

Causes of failure involve wear of lock moving parts combined with mechanical and electrical degradation over thousands of uses. Continuous hinge motions and detergent/cleaner exposure take their toll.

This Lid switch is also compatible with Kenmore units reliant on LG parts.
