Discovered during trouble shooting the problem that the activation button was failing if it was pushed by hand and the door closed immediately and start button pressed the door lock would work nearly every time the sequence was tried. the repair youtube showed me how to effect the repair. called for assistance in selecting the correct part (also ordered the door lock along with the button switch). Replaced the switch (same as the youtube) and it now runs correctly. Did not replace the door lock but will keep it for future use.
DYI easy, easy project. total time for repair was about 15 minutes, hardest part was making sure the door gasket was properly reinstalled.
your sales staff were excellent in making sure I was ordering the correct parts!!
