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.

Сначала выполнить:Do these first:

🧰 Tools

Phillips #2 Screwdriver
Socket Wrench
17mm Socket (3/8in Drive)
10mm Socket

ШагиSteps

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

Unfasten the rear panel

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

Remove the rear panel

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.

Unfasten the rotor

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.

Remove the rotor

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.

Unfasten the motor harness clamps

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

Unfasten the stator

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.

Reposition the stator

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.

Disconnect the rotor position sensor

Pull the rotor position sensor harness connector straight out of its socket to disconnect it.

Remove the rotor position sensor

Use your fingers to unclip the rotor position sensor from the stator.
Pull the sensor away from the stator to completely unclip it.

To reassemble your device, follow these instructions in reverse order. Take your e-waste to an R2 or e-Stewards certified recycler. Repair didn’t go as planned? Ask our Answers community for help.
