Have a u-line ice maker u-clr1215 fills the bin and then won't come back on

SOURCE: Frigidare FRS23KF6CB manufactured 03/07 ice maker water fill wont shut off

There is a float in the icemaker which controls water height. I'm going to bet the float is jammed or the switch it controls is bad.

Mark, your water valve has screwed the pooch. Replace it. The part number is 2199838.

What's happening is this... the valve that fills your ice maker is by-passing a small amount of water. This water has to flow through that tube, right? When very small amounts (drop by drop) go through the IM fill tube, they flash freeze. Eventually they (the frozen drops of water) form a big block of ice inside the fill tube. This ice creates a blockage which creates back-pressure whenever the IM "calls" for water. The back pressure eventually blows the tube off of the connection behind the fridge.

You say that this happened over night... no way. If you look closely at the ice cubes that you IM has been making, you'll see that they are hollow. Hollow cubes means that your IM isn't getting enough water... (because the fill tube is blocked).

I have the same problem -

SOURCE: LG ice maker only making two ice cubes at a time

Colenoid in the ice dispenser may be clogged or have a small amount of trash in it. Is there a filter on before the fridge (just after the ice maker shutoff)?

The Ice Maker Tray had a small plastic piece break off. This piece aids the tray in bending to dislodge the ice from the tray. Bosch does not just sell the tray, you will have to buy the whole ice maker assembly. You will need to order Part # 0422 from Bosch. I was not very happy about having to spend $112.00 for this whole assembly when all I really needed was a simple ice cube tray. 
Save the $112 and remove the ice maker. Buy Ice at the grocery store.
