We looked on You-Tube and found a video about this problem. The person that made the video showed that a broken switch behind the control panel was the cause of the problem. He stated that he purchased the parts from AppliancePartsPros.com. We ordered the parts online that evening and they were shipped out the next day via FedEx. We did not receive the parts and after contacting AppliancePartsPros.com new parts were shipped and received the next day. We are very happy with our experience with this website/company and blame the issue of not receiving our parts on FedEx.
