Hi,

I've got this ice maker, and there are two issues. Firstly, when it was making an abundance of ice, it would just keep making it and not stop when the bin was full. I suspect there is a sensor or something that has failed or that got knocked out of the way. Now the current issue. It seems to be not getting enough water in the reservoir. It makes ice fine, but it sounds like it is getting more air than water at times. If I pour water directly into the reservoir, it draws the water and quiets for a while, makes ice and then starts struggling again. I just replaced the water filter to rule out a clogged filter as an issue. Any thoughts?

Have you tried running the clean cycle? Are there any mineral deposits anywhere?

Did some thorough cleaning over the weekend and the issue persists. I did three or four cycles with white vinegar, than a few with distilled water, and then a few with the whirlpool cleaner solution. It looks like a simple appliance, but its a cramped spot in that box.

I took out the water inlet valve and tested for continuity, and it was fine. I checked water pressure going into valve and it was fine. I reinstalled and attached water in hose, and left out unconnected. I started machine and water trickled out of the valve. So, I suspect the issue is the valve. Is there a way to service these? Inspect and clean? It looks like one solid piece. W10217918

I just installed a new valve, and we have much more water in the reservoir, so I suspect we will be good for making ice. Now the other issue was that it did not stop making ice when the bin was full. Is there a way to test the thermistor to see if it has gone bad?

See if this helps:

The tech sheet will tell you how to enter service mode. The first three tests are the three thermistors.

I'm back...the previous fixes all worked, but this machine just doesn't want to stop throwing curve balls at me.

Current situation. Freeze plate not getting cold, so interior of unit is very warm. It was making ice on Monday, and has since melted it all...on the eve of 20 people coming to my house. I can hear the compressor start relay click, it sounds like the compressor runs for about two seconds, the relay clicks again, and the compressor stops. The copper pipes are cold to the touch. Thoughts?

It could be the overload or relay but that style rarely goes bad. Measure the compressor windings:
