The troubleshooting help from Appliance Parts Pros helped narrow it down to the problem being either the door switch, the belts, or the timer. A quick check showed the door switch was operating correctly. I assumed the belts were good since the other functions worked. That left the timer. I ordered the timer on Wednesday and it was on the doorstep within 24 hours. I had the washing machine operational that afternoon. Thanks for the tips and super service from the Appliance Parts Pros team.
