The ordering process and shipment was flawless. Although I did not use the parts which came, my problem was solved after watching a repair video. I will use the parts when needed in the future as necessary. Two comments made in the video triggered me to check the obvious components first: 1) from the door side, press lightly on the left switch white trigger to listen for a click. If there is no click, the switch is most likely bad. My switch clicked. 2) at the end you recommended replacing the switch mounts once you are in the unit. This led me to check the left mount from the door side to see if it moved or was loose. Mine was loose. I ordered the 3 switches and two new mounts, waited for them to come. Once they arrived two days later, I opened up the unit as you clearly showed ready to replace all switches and mounts. Sure enough, I found the left mount totally loose. After tightening down the left mount I tested the unit. It worked!
