Product review (4 stars): Not the easiest part to replace, but the washer works again, and that is what matters.
After accidentally leaving our machine plugged for part of the replacement of the rotor assembly of our LG front load washer, the machine wouldn't turn on. After replacing this part and the noise filter, we are up and running again. The install was a little more complex than some of the other repairs we have tackled, and we didn't find a youtube video to addressed this exact part. Once you get in there, you can figure out where things go. We also ended up having to replace the noise filter, so if you replace this part and your washer still won't turn on, try that part as well. We tested both the noise filter and the PCB separately and in our case, both had failed.
