I have a number of ice maker questions but to start, I wanted to show you a question/answer posted at the end of the ice maker parts page for my fridge on this site:

When I posted that question, the ice harvesting fingers were in the "home" position. As I started to troubleshoot this evening, I noticed they were at 6 o'clock (dead bottom of the ice tray) and stopped. So, I started with the first step above and jumpered the T and H pins on the motor control. Drop power to the fridge for 30 seconds and restore. As I opened the freezer door, noticed that the fingers were moving (I could hear the tickety-tick of the motor turning them), then they stopped at around midnight. No water. No more movement. Jumper still in place, I try again with the power down/up. No effect. I am thinking I have a bad motor assembly but I have other questions before I order more parts.

Since I have already replaced the optics and they appear to be working, I was wondering if there are any other "hidden" electronics? I see a plug for the ice maker motor/tray assembly. I know there are also plugs for both the optics boards and there is a connection to the solenoid valve for letting water in. Is that it? Are there any other hidden items that contribute to the function of the ice maker? It seems that the motor assembly controls the solenoid for water, the ice harvesting, the heating of the tray element during harvest, pretty much everything. If the motor is bad, nothing works.

I tested the water valve by swapping the connectors on the two valves. Water flows into the tray and the line is not frozen. I also noticed that the tray heating element was on during my test as my wife was helping me by checking for water and "burnt" her fingers on the tray (I think she was just startled to find something HOT in the freezer).

Seems to me everything checks but the motor assembly. Its function seems haphazard, at best. I am thinking replacing it is the next (hopefully last) logical step. This is what I am ordering if I can get a confirmation on my logic above.

Thanks Gene.

I had no idea there was a cement that's required. But I agree with you on the cost difference between the whole unit vs. two parts when you factor in new unit reliability. I was actually looking at that whole unit a week ago when you put the link in another post. The only reason I didn't do it was the compatibility checker said it was not the right unit for my fridge. Certainly looks like the right one to me and I could not find another whole unit that said it was OK for my model number. I think i will just order this and be done with it. With all the troubleshooting I have done, I am confident this will fix it.

Thanks again,
Steve
