LG WM3050CW Rotor Position Sensor Replacement

Difficulty

Moderate

Steps

Time Required

30 - 45 minutes

Introduction

Use this guide to replace the rotor position sensor in your LG WM3050CW Washing Machine.

The rotor position sensor is a Hall effect sensor that detects the primary motor's position, direction, and speed.

Tools

Step 1

Before you begin your repair, perform the following:
Turn off the main water supply
Unplug your washer
Disconnect all water connections at the rear of your washer

DO NOT USE THESE Instructions 🤦‍♂️. It will take you for ever. Go from the back, lie down on the ground take it I’ll put the new one in done. Or do it with someone you leave it a tad side ways and even easier

Step 2

Use a Phillips driver to remove the four 10.7 mm‑long screws securing the rear panel.

Step 3

Lift the rear panel upward to release its bottom clips.
Pull the rear panel away from the chassis to release the remaining clips.

Step 4

Remove the rear panel.

Step 5

Use an impact driver to remove the 17 mm nut securing the rotor.
Alternatively, you can use a wrench and a hammer to loosen the nut.
To secure the rotor, you can insert a screwdriver, or a similar tool, between the rotor and the stator. Make sure to brace the tool against one of the screw bosses on the stator.

Step 6

The rotor is magnetically attracted to the stator.
Pull the rotor straight off the stator and drive shaft splines to remove it.
Wiggle the rotor as you pull to help disconnect it.
This may require significant force.
During reassembly, watch your fingers when aligning the rotor over the stator, as the rotor gets sucked in easily.

Step 7

Use a Phillips driver to remove the three 16.6 mm‑long screws securing the motor harness clamps.

Step 8

Hold the stator up as you unfasten the last few bolts, as it can fall over unexpectedly.
Use a 10 mm socket wrench to remove the six 68 mm-long bolts securing the stator.
During reassembly, refasten the screws in a "star" pattern.

Step 9

Don't pull the stator too far away from the device, as it's still connected by wires.
Pull the stator off of the drum and flip it so its rear is facing upward.
Note the position of the stator before continuing, as you will need it face the proper direction during reassembly.
