Crushed ice only.No cubes.

Several possibilities, but check first for cubes that are too small (means too little water is coming in during ice maker fill) and those cubes fracture into smaller bits when they are dispensed.

Another possibility is the cube/crushed plate inside the dispenser is stuck. This is a curved plastic piece that lies next to the crusher blades inside the dispenser head of the ice storage bin. For cubes this place must be retracted (swing away from) the crushed fingers to allow the cubes to pass without being broken up.

Take out the ice bucket and check the metal arm and make sure it moves freely. Ice may have gotten stuck.

Hello friend, thank you for your post!

I understand that you are receiving crushed ice even when you request cubed ice. It could be an issue within your control panel or solenoid. Since it could be any one of these under lying issues I would recommend having a technician come out to properly diagnose your appliance. Hope this is helpful. -Matt

There is an metal arm that extends out behind the ice bucket that moves up and down when you press the cubed/crushed ice buttons. You need to take the ice bucket out and check the hardware. It's possible that some ice has managed to form in the unit and are blocking the motion. Remove any ice and check if the arm moves freely when you press the buttons on the refrigerator. Similarly, you should check if there is ice blocking the forward and back motion of the plunger in the freezer that bar sits on. This plunger is right next to the auger motor.

You will need to check inside the ice tray for anything that may have fallen in. Sometimes the ice itself with stick into clusters and will not dispense. I would take out the tray, empty it, rinse it and re install it. Good luck!

This answer probably comes too late for you (you posted the question 9 months ago), but I want to record it here for posterity, since I had the same problem, and searching on Google for it brought up your question.
Anyway, I managed to fix this very problem by removing an ice cube that was wedged in the ice dispensing mechanism. The way this unit works is that it pushes the ice cubes through the mechanism, which always rotates the "crushing blades". When you select "cubed" ice, a lever opens up the exit chute wider, which causes the blades to simply push out the ice cubes as they pass through. When you select "crushed" ice, the lever closes the "exit" for the ice cubes to be narrower, so that the ice cubes can't be pushed through by the blades, and instead get crushed by them. I had an ice cube wedged in there that had the same effect of closing the exit to be narrower. Removing it fixed the problem.
You might want to collect all the ice cubes that have accumulated in the ice bucket in a container, empty the ice bucket, clean out the mechanism from any obstructions, and then put the ice cubes back into the ice bucket.

ice maker works. water thru the door works. lock works. light works, alarm works.
when i try to get crushed, ice cubes or quick ice.
nothing happens

You have a solenoid switch which switches the dispenser back and forth from crushed to cube. It could be stuck or not working or the parts connecting it could be disconnected or broken. You will have to observe to see if any parts are moving and if any noise is coming from the solenoid

your model # is incomplete but here it goes.

1.take your ice container out and run hot water thru it. you want to defrost all of the ice build up inside of it's housing.
2. make sure the long lever under the container moves up & down when you press on it.
3.w/the container removed, you will see a fork like object and next to it amn openning w/a small plastic square part inside. make sure that part moves freely up & down. that solenoid is what gives cubed ice.

let's start there first

We've had a similar problem, possibly the same, with our LG in-door ice maker. Whether cubed ice or crushed ice is selected, it crushes the ice.

We found that there is a little lever on the inside of the door, on the lower right behind the ice bin, which freezes in the down position. This is a literal "freeze up", as a block of ice forms in the little well under this switch and eventually freezes the switch in place. Since the switch needs to go up to provide cubed,.. we only get crushed. On 3 separate occassions we've thawed and chipped out (carefully) this little ice dam and gotten cubed ice capability back for a few weeks. At which point it freezes again. I have no idea why water collects there in the first place.
