The ice dispencer accumulates ice and clogs the opening. also the dispenser only servers crushed ice even when the cube button is pushed

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

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 dispencer does not dispense cube or crush ice. Water comes out, lights work. it is not deactivated.

Not sure what brand you have but I had a similar problem with a dispenser once. The ice dispenser would freeze up and couldn't change over from one to the other and I'd have to take it out and let it thaw occasionally and then it would be fine for several months again. If your ice bin is in the door this may be what you need to do.

If you remove the bin and look on the bottom of it you will see a rod running from front to back,this opens and closes the crusher see if it moves freely, if not dump the ice and rinse the bin out with hot water till it moves freely,if so,with the door open set the dispenser to cubes leave the bin out push the light switch in and hit the  dispenser button you should hear a loud pop and see the actuator by the auger motor move up,and drop down when you release it.

The dispencer my be plugged, take it out and let it thaw for a day and then clean and replace it.

We have had this problem on occasion. The lever up in the ice dispencer gets jammed with frost and ice. If you remove the ice bucket/auger and let it thaw or just rinse it with water and dry it. Give it a try. -Matt

There is a solinoid in the freezer section by the motor that turns the ice auger. Test it by selecting cubes and with the ice bucket out, open the door, hold the door switch so the lights turn out and push the dispenser button. It should make a loud snap and travel upward. If not then I would say you have a bad solinoid. If it does, then I would look at the bucket. the metal rod that runs along the side of the bucket opens a flap in the bucket that is supposed to let the full cubes drop. look for anything that might cause it to be hanging up.

could be a problem with micro switches inside the dispenser. it has small switches that when you press the button outside, you are pressing a switch inside and if they are cross wired or what ever, these things happens. if you are familiar with electrical wiring trouble shooting, then i could guide you but if not, then i suggest you call a qualified tech to help you with this kind of problem.

it is as if the wires were interchange. cube button would dispense crushed ice then the crushed ice button is not working.


tnx 4 using fixya,

drcool

two possibilities, either the gate at the dispenser is clogged or the solenoid valve tht operates the gate is bad
