Product review (4 stars): Has your machine started to growl during the wash cycle? This is probably the part you need.
Our 7 year old LG front loader was making a low growl during the wash cycle, but the drum was still spinning, for close to a week before the growl turned into a howl and the drum refused to turn. Referencing a youtube tutorial, we replaced this piece with some ease - but from one intrepid DIYer to another, please REMEMBER TO UNPLUG YOUR MACHINE before beginning the repair. While the repair was quick, we accidentally left our washer plugged in until the old part was removed, and when the new part was in, the machine would not power on. No amount of troubleshooting could get it to come on. We ended up having to replace the Noise Filter AND the Power Control Board (we tried it with each separately, it only worked when both had been replaced.) Now, things are going great, and in a family of 8 with 1-3 loads running a day, that is a meaningful thing.
