Ice Maker Quit

Just take it out and purchase a new one at Amazon. Last one I replaced was around $30. I don't think the unit is worth troubleshooting.

Ok I will describe how the thing works starting with when the cubes hit 25 Degrees
A thermostat closes and starts the motor running. and a heater heating.
As the fingers hit the ice cubes the motor stalls.. (I am assuming cresent shaped cubes, there is another type) once the surface of the ice melts the motor agains continus running pushing the ice out of the tray and eventually scraper fingers scrape it off the pushers and it falls into the tray.
Meanwhile as the wheels turn a switch sends power to the solenoid allowing water to flow.

possible issues.
Most common: Ice in the water line.. water can not get past it
Split water hose (Solenoid to ice tray) Water all over outside compartment

After that it gets hard to fix as parts are needed.. You can check for power to the solenoid during cycling by hooking a volt meter or 120 volt test lamp to the leads and force cycling the unit.. You should hear the CLICK when the solenoid engages as well. You can check by disconnecting the solenoid to ice tray line and hooking a short tube on as a temporary and see if water flows during the cycle. If it does the unit is iced or the delivery tube split. If the tube is split water will be seen in the outside compartment where it should not be.

Turns out replacing the line is not as hard as it looks You just need to tilt the Fridge into the RV (Disconnect gas line first)

Finally: How I fixed mine.
Pulled it out and got a counter top ice maker.

First thing I would do, is shut it down and let the refrigerator warm up to room temperature over night. Then turn it back on and see what happens. Mine freezes up from time to time. I leave mine on 24/7, when you don't go in it for a long time, it will get cold soaked, freezing the feed line.

I also do what Hoefler does.

I have also poured warm water into the ice tray when cubes seem to be trapped and cannot be moved.

It could as simple as a clogged valve strainer.

I just completed a total defrost. Will see if that helps. There is no water showing in the rear or bottom of the fridge. Thanks for all the suggestions. I will let you know how I make out.

Does if make any sound at all? Clicks, sound of a small motor running, water flowing?

Ranger Smith, where did you get a replacement ice maker for $30?

I believe it was on Amazon or Appliance Parts Direct. They went up in price and are now 45.00 to 65.00 on Amazon

The ones I am seeing on Amazon are from $222 to $400.
