As a last ditch test, before ordering a new icemaker, I tried something I saw on another forum. I took the wires from the door dispenser valve and connected it to the ice maker valve. I then pushed the water dispenser in and I should have gotten water flow to the ice maker. I did not get any flow, so it appeared the problem was not with the ice maker unit and I need to brush up on electrical testing skills. I then disconnected the water line where it feeds into the ice maker near the top/back of the fridge and tried it again - got water! Turns out the fitting was frozen. I had read that this may be a source of the problem, but could see no issues from the front. A hair dryer, a straw to blow into the fitting and 5 minutes later, Bingo, back in business. Apparently the water flow was not as good as I thought it was. Going to replace the water filter before I reinstalling the ice maker. Just a note if you are going to try something similar. I also read that the light switch for the freezer also functions to prevent the ice and water dispenser from working while the door is open, so I taped it over so it thought the door was closed. Live and learn........Thanks for all the help.
