Chrissy T Grafton , NH March 11, 2022 The washer's door lock sensor. Super easy - remove screws, door gasket spring and simply remove old put on new. The only issue I had was separating the two connectors as my fingers are not strong. *I have to add how excited I was at how quickly my part came! What a blessing.
