Check water turned on. check ice button switch turned on in fridge. remove juice storage, ice container in freezer, check ice bucket full white plastic flapper to make sure not stuck on a white peg at top. flapper must hang down and be freely movable to signal ice maker to keep busy. If up high will turn off ice maker. Lots of other parts especially heater circuits involved also: fill tube supply heater not working then frozen supply line then no ice. Look for wiring diagram in ziplock behind compressor grille. can order parts at repairclinic.com. logical design, layout, easy to get to sensors, heaters. makes sense if look at it long enough.

When my repair tech came out, he showed me that the fill tube sometimes retracts toward the rear of the freezer. He simply pulled it forward with a pair of needle nose pliers until it rested in the delivery reservoir. This placement allows the detector to know when the tray is full and shut off; thus not overfilling the freezing tray and/or splashing additional water onto the freezer wall and into the ice cube drawer.

Call the factory at 800-222-7820 for the manual. It souns like you are missing one or two screws. Pull the ice tray out and lift it up about an inch and it should release. Take a look at the ice maker and there are two supports that both need to have screws on them. There is also a third underneath on some models. Insert the screws and you should be fine.

SOURCE: Ice Maker won't work
If your trying to save a service call you have your work cut out for you. The ice maker is a unit that sits by itself attached to the wall or part of the freezer wall.
There are many reasons why you do not get ice and I will list them.
1- Temp of freezer got too cold and has frozen the pipe that feeds the water to fill the icemaker.
check to see if the icemaker has any ice in the area that fills and makes the cubes.
If the pipe is clogged, very gently put a small tipped screw driver in the fill hose that sites over the ice making row in the ice maker. Be careful you do not push your screwdriver out the back of the refer.
Check to see the freezer temp is not too cold and is freezing that pipe. 0-3 degrees F is good.
2.- check to make sure your water feeding the fridge is on. There is an on off valve to allow the water to feed the icemaker when it needs to fill. This could be bad. there are reset proceedures for the fridge, but unplugging the entire frige for 1 minute and plugging it back in you can listen for the the valve to come on and see if it fills the ice maker resevoir.
3. If it fills and freezes the ice resevoir, then the sensor in the ice tray does not sense the frozen ice and will not cycle and kick cubes. At this point, unless you are super tech, you will need to replace the entire icemaker unit.
Hope this helps.

Here is a link to the error codes. If there is a fault condition these should be flashing on the display:
One this to try is a hard reset: unplug and wait for a few minutes and re-plug back in. Sometime this resets the service condition and will then display the error codes.
Ice is displayed when the ice maker is turned on. Press the ice on/off and it should turn off.
