Product review (5 stars): Part easy to replace.
For several months it was difficult to get our Samsung Front Load Washer door to lock.  We found that if we leaned on the door when we started the wash that eventually it would lock.  Then it got to the point where even that didn't work.  This video, https://www.youtube.com/watch?v=Y-eAvoBI59Y, showed how to replace the lock and it really was just as easy as it shows it.  We ordered the Lock solenoid, it arrived a couple of days later, and in about 15 minutes I was able to remove and replace the old broken solenoid.  It is so nice to have the washer working properly again - I wish I would have replaced the solenoid months ago.
Amazon had a great price on this solenoid, and our order was filled and delivered promptly.
