I ordered the infinite switch from AppliancePartsPros.com and my son exchanged the old for the new in a matter of minutes and now it works the way it is supposed to work. AppliancePartsPros.com is a model for other businesses on how to do business. The site is well designed, simple to use, and easy to select the part needed. They responded to my email when I wanted to make sure I was ordering the part I needed and the part was sent out immediately as it was in stock.
