Found a knowledgeable qualified agent at AppliancePartsPros.com that found the upper and lower door bins were not correctly illustrated...In fact, they were opposite...a Whirlpool mistake...The top bin 13 on the drawing was actually the lower bin part number, and the lower bin 4 on the drawing was actually the top bin part number...With that little effort, paying attention to detail of the description of the size of the bin, the agent/tech ordered the correct lower bin for me...When it arrived, it was a simple matter of installing it in the door...I spent several days with Sears Parts, local Sears store, Whirlpool, and a big run around...With a clue from a parts search blog, the AppliancePartsPros.com tech discovered the problem in a short time, and ordered the part for me...Thanks, AppliancePartsPros.com...for doing an excellent job...For further appliance needs, I will definitely contact AppliancePartsPros.com first...
