I ordered a new touch panel, # AP4500584 on Jan. 26 8:59 AM. It was shipped the same day. To my surprise it arrived on the 27th before noon at 11:26. It took me 8min to put back together and test to make sure it was working. So happy I only had to wash my dishes by hand 1 day. It was great knowing if the part did not work that I could send it back, no questions asked. Thanks Appliance Parts Pros.
