Product review (5 stars): Fixed the problem!
When our washing machine stopped working after about 3 years, we were really concerned that we were going to have to buy another washer/dryer combo.  Every time we tried to start the washing machine, we would get the warning buzz indicating that the door was ajar.

After doing a little research, I found out how to check error code which lead me to this part.  The part was easy to access and replace.  Our washer works again.  This is a bargain compared to buying a new washer!
