The knob one turns to set the humidity level was removed. The two screws holding the top on were removed. The top was lifted and swung to the side. After noting which of the two wires went where on the humidistat the wires were removed. Small flat screwdrivers were used to pry back the plastic retainers on one side of the original failed humidistat. The new one was put in place, the two wires were reattached. The knob was replaced. The top was positioned and its two retaining screws replaced. A magnetic phillips screwdriver was handy but not necessary. Piece of cake! Someone with ten thumbs could do it!! Thanks for the prompt courteous attention to the returned erroneous part! Dealing with partselect. Com was a pleasure. . . . . . Thanks!! P. S. The dehumidifier works like new now!!
I was able to pull the old wheel off and then went to google on the computer and put in whirlpool dehumidifier. I was directed to a website where I could put in the model # of the appliancew and then was able to view pictures of repair parts. I was able to view the actual caster and determine that I was ordering the right one. The part came about 3 days later and I was able to snap it on without using any tools. There was alittle plastic guide to hold aside and slide the new caster in place.
