We had a repair man come out and diagnose the problem. This part was not in stock where he orders his parts. He was nice enough to give me the part number. I had seen the ad for Appliance Parts Inc. and ordered it online it was also cheaper than the part he quoted me. We watched the video of How to install the MCU. So we followed the very easy to comprehend video and installed it ourselves. It works and this morning I'm on my third load of clothes.
